Treating Supraventricular Tachycardia In Hospital

What To Do If Your Heart Rate Spikes When You Start A Run – Should You Be Concerned?

SVT is rarely life threatening. But you may need treatment in hospital if you keep having long episodes.

This may include:

  • medicines to control the episodes of SVT given as tablets or through a vein
  • cardioversion a small electric shock to the heart to help it get back to a normal rhythm
  • catheter ablation a treatment where thin tubes are placed through a vein or artery into your heart to correct the problem with the electrical system; this permanently cures the problem in most patients

What Are The Symptoms Of Arrhythmia

Some patients have no associated symptoms with arrhythmia, while others may notice symptoms but not have a life-threatening arrhythmia.; It is important to have regular check-ups with your GP, especially if you are concerned.

Common symptoms of a heart arrhythmia include:;

  • Fluttering feeling in the chest
  • Racing heartbeat
  • Alternative medicine including yoga, meditation or relaxation techniques;

Treatment for abnormally fast heart rhythms

Generally, patients with abnormally fast heart rhythms can be treated with drugs that slow the heart rate or may be treated with a procedure, known as catheter ablation. This involves passing a catheter up through a vein into the heart and burning away the small regions of the heart that are causing the arrhythmia.

Treatment for abnormally slow heart rhythms

Patients with abnormally slow heart rates are most effectively treated with an electronic pacemaker which sends regular electrical signals to the heart to ensure that it beats at a normal rate.;

How Is Inappropriate Sinus Tachycardia Treated

  • Eliminate potential stimulants in your diet such as caffeine, nicotine, and alcohol
  • Take medicine to slow the heart rate such as ivabradine, beta-blockers, or calcium channel blockers.
  • Exercise to improve quality of life and to maintain a healthy heart

IST is often hard to treat. If you have severe symptoms that dont respond to these treatments, you may need catheter ablation. This procedure uses energy to destroy a very small part of the heart that is triggering the tachycardia. But it doesnt always work because the whole heart can be abnormal. There is also a small risk that destroying too much heart tissue might make a permanent pacemaker necessary.

Normal Resting Heart Rate For Kids

Childrens heart rates are normally faster than those of adults. According to Cleveland Clinic, the normal resting heart rate for a child aged six to 15 is between 70 to 100 beats per minute.

Many factors can affect your resting heart rate, including your level of physical activity. In fact, highly trained athletes can have a resting heart rate of around 40 beats per minute!

Other factors that can affect resting heart rate include:

  • Age. You may find that your resting heart rate decreases as you get older.
  • Temperature. Your heart rate may increase slightly when youre exposed to hot temperatures.
  • Medication side effects. For example, medications such as beta-blockers can lower your resting heart rate.
  • Emotions. If youre anxious or excited, your heart rate may increase.
  • Weight. People who are obese may have a higher resting heart rate. This is because the heart has to work harder to supply the body with blood.
  • Body positioning. Heart rate can increase temporarily when you move from a sitting to a standing position
  • Smoking. Smokers tend to have a higher resting heart rate. Quitting smoking can help bring it back down.

Why Foods Cause Heart Palpitations

Why Does My Heart Rate Spike When Im Asleep?

Feeling palpitations after eating is a relatively common experience, which tends to occur when a substance in your food or drinkor your bodys natural biochemical response to that substancejolts the hearts electrical system and causes fluttering sensations, skipped beats, or a feeling that your heart is beating too hard or too fast.

Coffee drinkers, think about the last time you drank one cup too many. You know what I mean!

If your heart is healthy and you have no history of arrhythmia or heart diseaseand youre not experiencing any other symptomstheres little need to worry about an occasional episode of these irregular beats. For people who do have arrhythmias;or cardiac issues, however, its a different story. Palpitations caused by food can cause an existing disruption in your hearts rhythm to escalate, and potentially lead to a major event.

Changes In Heart Rhythms Are Usually Harmless

Our heart rate adapts to our bodys need for energy throughout the day, whether its for walking up the stairs or a bout of strenuous exercise. These tempo changes based on physical activity are perfectly normal.

Other common situations can trigger changes in heart rhythms too. Mild dehydration can cause the heart to beat more quickly; thats the bodys way of trying to maintain the flow of blood when theres less available for every beat.

A change in medication, or an interaction between medications, can trigger a temporarily abnormal heartbeatanother reason to always share medication and supplement routines with your health care team. And while the resolution can be simple , its sometimes beyond our ability to understand why we feel a change in our heart rhythms or if its the symptom of a more urgent medical situation.

How can I nurture healthy heart rhythms?

The things you can do to support heart-healthy rhythms are the things youd do to support general health and cardiovascular health, says Johns Hopkins expert Mark Anderson, M.D., Ph.D. Live in moderation. Get enough sleep. Control risk factors like hypertension, diabetes and cholesterol. Engage in regular physical activity. Dont smoke or drink too much alcohol. And eat a balanced diet.

Key Points About Inappropriate Sinus Tachycardia

  • In IST, the heart rate sometimes increases abnormally. You may have episodes in which the heart rate increases above 100 beats per minute.
  • Sometimes, the heart rate increases on its own. Other times, the heart rate increases because of a trigger. But it increases more than it should.
  • Some people dont have any symptoms from IST. But others do.
  • Possible treatments vary depending on the severity of your symptoms.
  • It may help to avoid potential triggers, like caffeine and nicotine and any other triggers you know cause IST.

Causes Of Awakening From Sleep With A Racing Heart

Spike in heart rate while exercising. Heart palpitations during cycling, screen shot of high beats.

This is most commonly caused by anxiety that could result from underlying stress or a bad dream, says Morton Tavel, MD, Clinical Professor Emeritus of Medicine, Indiana University School of Medicine, and author of Health Tips, Myths and Tricks: A Physicians Advice.

1;; Side effects of medications like those for cold, or asthma inhalers

2;; High caffeine intake before bedtime

3;; Drop in blood pressure while asleepthe heart speeds up to compensate to make sure theres enough blood circulating throughout your body. Causes are many including pregnancy.

4;; Drop in blood sugaragain, the heart speeds up to compensate. Causes include strenuous exercise with inadequate recovery nutrition.

5;; Hyperthyroidism , though youll likely have additional symptoms like unintentional weight loss or feeling hot when nobody else in the room does.

6;; A less likely cause would a heart rhythm disorder that results in an inappropriately rapid rate, says Dr. Tavel.

In this latter case, the problem is usually benign and often resolves spontaneously.

The condition is called supraventricular tachycardia, of which there are several types.

People who have this are primarily young adults. It can last minutes to hours and be accompanied by a tight chest and feeling breathless.

Dr. Tavel also explains, In some instances, it can be terminated by vigorous coughing or by breath-holding combined with bearing down .

If it doesnt stop within about 20-30 minutes, medical attention should be sought promptly.

What Are The Risk Factors For Paroxysmal Supraventricular Tachycardia

PSVT affects about 1 in every 2,500 children. It is the most frequent abnormal heart rhythm in newborns and infants. Wolff-Parkinson-White syndrome is the most common type of PSVT in children and infants.

PSVT is more common in adults under age 65. Adults over age 65 are more likely to have atrial fibrillation .

In a normal heart, the sinus node directs electrical signals through a specific pathway. This regulates the frequency of your heartbeats. An extra pathway, often present in supraventricular tachycardia, can lead to the abnormally fast heartbeat of PSVT.

There are certain medications that make PSVT more likely. For example, when taken in large doses, the heart medication digitalis can lead to episodes of PSVT. The following actions can also increase your risk of having an episode of PSVT:

  • ingesting caffeine

In more serious cases, PSVT can cause dizziness and even fainting due to poor blood flow to the brain.

Sometimes, a person experiencing symptoms of PSVT may confuse the condition with a heart attack. This is especially true if its their first PSVT episode. If your chest pain is severe you should always go to the emergency room for testing.

If A Racing Heart Is Waking You From Sleep This Can Be Even Scarier Than Pvcs

When youre sleeping, your body is at its lowest energy needs, so why would your heart suddenly start racing?

What awakens you is the sudden racing of your heart, provided that youre not in a deep sleep.

Any deviation from the normal minimal state that your body is in can be enough to pull you out of slumber.

Of course, when that deviation is a racing heart, and youre just lying there in the middle of the night in a dark room, this can be quite alarming.

What Are The Symptoms Of Ventricular Tachycardia

During an episode of ventricular tachycardia, the heart is beating so fast that the blood pressure drops so the heart cannot pump enough oxygen to every part of the body, and this is what causes symptoms. Although some people with ventricular tachycardia do not experience any symptoms, the most common symptoms are dizziness, lightheadedness, palpitations, shortness of breath or chest pain. When the heart rate is extremely high or the ventricular tachycardia persists for more than a few seconds, it can cause fainting, unconsciousness or cardiac arrest and death. If you experience unexplained fainting, dizziness, lightheadedness, shortness of breath or palpitations, you should be evaluated for possible ventricular tachycardia. Chest pain, difficulty breathing and a rapid pulse are urgent symptoms of a potentially fatal ventricular tachycardia, and you must seek emergency help immediately to avoid the risk of cardiac arrest and death.

SVT symptoms heart palpitations, chest pain, shortness of breath, dizziness or lightheadedness can be alarming, but the condition is usually treatable and can often be cured, says Michigan Medicine electrophysiologist Rakesh Latchamsetty, M.D.

First, he says, the type of arrhythmia responsible for the symptoms needs to be determined since different arrhythmias can be treated very differently and some can be more serious than others.

A person experiencing a rapid heartbeat should consult with their physician, and anyone experiencing unrelenting palpitations or severe symptoms should be seen in the emergency room, says Latchamsetty.

Preparing For Your Appointment

To prepare for your appointment, see the topic Making the Most of Your Appointment.

You can help your doctor diagnose and treat your condition by being prepared to answer the following questions:

  • Do you have a history of problems with your heart rate or rhythm? If so:
  • Did you see a doctor?
  • What was the diagnosis?
  • What tests were done?
  • How was it treated?
  • When did you first notice the change in your heart rate or irregular rhythm? What were you doing when it started? Were you walking, standing, sitting, or lying down?
  • Is the change in heart rate or irregular rhythm related to activity, or does it happen when you are resting?
  • How often does the change in heart rate or irregular rhythm occur? How long does it last?
  • Is the change in heart rate or irregular rhythm related to eating?
  • What does the change in heart rate or irregular rhythm feel like?
  • Did you have other symptoms with the change in heart rate or irregular rhythm? What were the other symptoms?
  • What have you tried at home to relieve the change in heart rate or irregular rhythm?
  • Do you have any health risks?
  • If you have kept a record of your heart rate or rhythm changes, be sure to discuss this with your doctor.

    The Hill: Too Exhausted For Bed

    If your RHR increases right after you fall asleep, this could be a sign of exhaustion. Did you go to sleep on time? If its past your regular bedtime, you may start feeling the effects of increased melatonina hormone that aids sleepand lower blood pressure. This communication from your body serves as a warning of sorts, reminding you to get to bed on time.

    If you did go to sleep during your ideal bedtime window, its possible that your heart rate may be increasing at the start of the night for reasons you cant control. For instance, your airways may have relaxed during sleep, causing you to snore, which raises your heart rate.

    Learn The Prevention Measures

    Certain measures can be taken to prevent a sudden increase in heartbeat;or it becoming a health concern.

    Ablation by Radiofrequency Catheter

    Catheters are made to enter the heart through blood vessels. Electrodes are present at the catheter ends; they are heated and used to damage or ablate the small area of heart that is causing the fast heartbeat.


    Anti-arrhythmic drugs, if taken regularly can help in preventing tachycardia. Your physician may prescribe other medicines that should be taken along with anti-arrhythmic drugs including channel blockers, such as Cardizem and Calan , or beta-blockers, such as Inderal and Brevibloc .


    It is a device, which monitors your heartbeat continuously. It is implanted surgically into the chest. It detects any abnormality in heartbeat and gives electric shocks to bring back heart rhythm to normal.


    In some cases surgery is required to remove an area of tissue. This is only done in cases where other therapies are ineffective or if the patient has another disorder of the heart.


    Warfarin makes blood clotting difficult and is generally given to persons who have moderate or high risk of having heart attack or stroke. Though, with warfarin the risk of bleeding is raised, it is given to persons, in whom, the risk of heart attack or stroke is greater in comparison to risk of bleeding.

    Average Sleeping Heart Rate By Age

    Heart attack rates spike in the winter

    The resting heart rate for most healthy adults should fall between the 60-100 beat per minute range, with the scores closer to 60bpm than a 100.

    We highlighted the term adults because, for children, it is a whole different ball game.

    Kids post relatively higher heart rate figures during the early stages of their development, including those for resting heart rate. However, these figures gradually begin to slow down until they reach adolescence, by which their RHR would have typically normalized to the 60-100bpm range.

    Consequently, your age is one of the most substantial factors influencing what healthcare practitioners consider the normal sleeping heart rate for you.

    Based on data from the National Institutes of Health, here is a list of the typical sleeping heart rate by age.

    Age Group
    Over 10 years 60-100

    Note: Seasoned athletes and other people that regularly participate in rigorous exercises and tasks typically post low RHR scores of around 40-60bpm. Although these figures fall below the recommended normal rate, in well-trained athletes, this is a sign of good health.

    In the early stages of their development, healthy children typically have significantly higher heart rates, even at rest.

    This significant skewing from the mean stems from the fact that babies have considerably higher rates of metabolism, which places more strain on the heart and warrants a faster bpm and a more active circulatory system.

    I have noticed an occasional;strange spike in my heart rate late at night when I am asleep. It’s happened a few times now, most recently on Saturday evening.

    It shows on the app as happening around 23:59, and my heart rate jumps up from around 60 to 150, although in one instance it was 170.

    I am assuming it’s a bug/glitch, as it happens at the same time of night;each time;but I’d like to know what is causing this issue.

    I’ve had another one of these spikes this week – anyone know what might be causing them?

    Ah I just posted a similar thread about it…. Maybe it’s a glitch? Or both of us are about to have a stroke / horrible nightmares.;

    Not sure if your graph looks similar?

    My graph looks different, there’s just one spike at roughly the same time at night.

    I think yours looks like a gitch…. Guess I need to investigate mine!

    ;This does seem odd. Have you tried restarting your tracker? If you haven’t then please do the following:

    Also do you have any alarms that may be set at that time? Of something that may wake you up at that time ? I do think it is something related to the tracker or app and not something external but I just wanted to know if there are any external factors.
