Capturing Heart Palpitations In Action
If you are at risk for a heart rhythm problem, or if palpitations are interfering with your life or mental health, a recording of your hearts rhythm for 24 hours or even longer may capture an electrical signature of the problem. Getting visual evidence of this signature can help determine how best to treat your palpitations.
A Holter monitor constantly records your hearts rhythm for 24 hours as you go about your daily activities. Small patches called electrodes are stuck onto your chest and attached to a recorder that you carry in a pocket or wear around your neck or waist. During the test, you keep a diary of what you are doing and how you feel, along with the time of day of each entry. When you return the monitor to your doctor, he or she will look at the recording to see if there have been any irregular heart rhythms.
Twenty-four hours often isnt long enough to detect palpitations. An event recorder can monitor the heart for days or weeks. Theres even an implantable recorder that can invisibly monitor the heart for a year or more.
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
- shortness of breath
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.
Slow Heart Rate Questionnaire
Heart attacks occur because of a decrease in blood flow to the heart. This is caused by a blockage in one of the hearts major blood vessels. In about 15% to 25% of heart attacks, the blood vessel thats blocked also supplies oxygen to your hearts electrical system. When the heart doesnt get enough oxygen, you may experience a slow heart rate.
Call 911 or go to the ER right away if you suspect youre having a heart attack. Treatment depends on the severity of the heart attack. It may include a combination of medications, stents , and surgery.
Treating a heart attack usually restores normal heart rate. However, a small percentage of people may need to get a pacemaker to control their heart rate.

How Is Paroxysmal Supraventricular Tachycardia Diagnosed
If you have an episode of fast heartbeats during an examination, your doctor will be able to measure your heart rate. If its very high, they may suspect PSVT.
To diagnose PSVT, your doctor will order an electrocardiogram . This is an electrical tracing of the heart. It can help determine which type of rhythm problem is causing your fast heart rate. PSVT is only one of many causes of abnormally fast heartbeats. Your doctor will also likely order an echocardiogram, or ultrasound of the heart, to evaluate the size, movement, and structure of your heart.
If you have an abnormal heart rhythm or rate, your doctor may refer you to a specialist who is an expert in electrical problems of the heart. They are known as electrophysiologists or EP cardiologists. They may perform an electrophysiology study . This will involve threading wires through a vein in your groin and up into your heart. This will allow your doctor to evaluate your hearts rhythm by checking the electrical pathways of your heart.
Your doctor may also monitor your heart rate over a period of time. In this case, you may wear a Holter monitor for 24 hours or longer. During that time, youll have sensors attached to your chest and will wear a small device that records your heart rate. Your doctor will assess the recordings to determine if you have PSVT or some other type of abnormal rhythm.
A Elevated Pulse Rate Is Known As Tachycardia Which May Be A Normal Response To Some Stimuli Or Part Of Some Medical Conditions
The heart of a healthy adult beats within the range of 60-100 times per minute at rest. This rate is controlled by electrical signals within the heart. An abnormally high pulse rate above 100 beats per minute is also called tachycardia, and it occurs when the heart tissues produce electrical signals rapidly, affecting the upper or lower chamber of the heart, or both.
Tachycardia, or rapid heart rate, may produce either a regular or an irregular rhythm in the heart. At extremely rapid rates, the heart may not be able to pump oxygen-rich blood efficiently to the rest of the body, and may cause symptoms as well as complications.

Understanding Changes In Resting Heart Rate
Robert J. Myerburg, MD, is a professor at the University of Miami Miller School of Medicine who for 31 years served as chief of the schoolâs division of cardiology. âWe have known for a long time that a higher heart rate is associated with increased risk for heart disease,â he says.
The people in the new study were healthy, he points out. The new study findings may not apply to people with heart disease.
Donât panic about these findings, says Kousik Krishnan, MD. He is director of the Arrhythmia Device Clinic at Rush University Medical Center in Chicago. âPeople who have a heart rate that goes up over time may have some other underlying condition,â he says. âIf you have a resting heart rate that is over 100, ask your doctor to do a physical exam to see if something else is going on.â
Suzanne Steinbaum, DO, says the study provides empowering information. She is a preventive cardiologist at Lenox Hill Hospital in New York City. âResting heart rate gives us an indication about our heart health,â she says. âThe best way to keep your resting heart rate down is aerobic exercise.â
This means that if your resting heart rate is edging up, your activity level has probably taken a dive. âYou are still in control,â she says. âStart exercising more and see a doctor to make sure something else isnât going on.â

Why Does Bradycardia Happen
The most common cause for bradycardia is a malfunction in the hearts natural pacemaker, the sinus node. It controls how quickly the top and bottom heart chambers pump blood through the body. Another cause is atrioventricular block , in which the top and bottom chambers dont communicate well and the heart rate drops as a result.
Its like having virtual electrical cables and wires inside the heart, Dr. Baez-Escudero says. And, they deteriorate as we age. Common medications that are used in older populations can also often make bradycardia more significant.
In fact, age is the most common risk factor for developing bradycardia. The condition is most common among men and women over age 65.
Illness or other conditions also may prompt it. These other causes include:
- Heart attacks due to coronary artery disease.
- Bacterial infection in the blood that attacks the heart.
- Inflammation of the heart muscle.
- Low thyroid function.
- Certain medications, including beta blockers and antiarrhythmics.
Congenital heart defects, diabetes or long-standing high blood pressure all may make bradycardia more likely, Dr. Baez-Escudero says.

How Are Arrhythmias Treated
Many arrhythmias dont need treatment. For those that do, these options might be used:
- Medicines. Many types of prescription anti-arrhythmic medicines are available to treat arrhythmia. Sometimes, these can increase symptoms and cause side effects, so the patient will be closely watched by the doctor.
- Pacemakers. A pacemaker is a small battery-operated device implanted into the body through a surgical procedure. Connected to the heart by a wire, a pacemaker can detect if the heart rate is too slow and send electrical signals to speed up the heartbeat.
- Defibrillators. A small battery-operated implantable cardioverter defibrillator is surgically placed near the left collarbone. Wires run from the defibrillator to the heart. The ICD senses if the heart has a dangerously fast or irregular rhythm and sends an electrical signal to restore a normal heartbeat.
- Catheter ablation. A catheter is guided through a vein in the leg to the heart. Arrhythmias often are caused by microscopic defects in the heart muscle. Once the problem area of the heart is pinpointed, the catheter heats or freezes the defective muscle cells and destroys them.
- Surgery. Surgery is usually the treatment recommended only if all other options have failed. In this case, a person is put under anesthesia and a surgeon removes the tissue causing the arrhythmia.
Fast Heartbeat After Eating
It is common to notice your heart run faster than usual after eating a heavy meal. It may also happen when your meal includes stimulants such as sugar or caffeine. However, your heartbeat should become normal once you have digested your food. You may want to see your doctor in case your heart keeps racing several hours after you have finished your meal. There can be many reasons of having a rapid heartbeat after eating, and knowing the cause helps find the best treatment.

What Makes A Heart Rate Soar
Typically, a normal resting heart rate falls between 60 and 100 beats a minute, according to the Mayo Clinic. An abnormally fast resting heart rate â called tachycardia â happens when the upper or lower chambers of the heart beat more than 100 times a minute, explains Shoshana Ungerleider, MD, an internist who practices hospital medicine at California Pacific Medical Center in San Francisco.
“It is normal for your heart rate to rise during exercise or as a physiological response to stress, trauma or illness,” says Dr. Ungerleider. “This is called sinus tachycardia.” Not all types of tachycardia are benign, however. According to the Mayo Clinic, other types that come with health consequences include:
- âAtrial fibrillation ââ a fast heart rate caused bydisordered, irregular electrical impulses in the heart’s upper chambers, knownas the atria.
- âAtrial flutter ââ when the atria of the heart beat rapidlybut at a steady rate, resulting in weak atrial contractions.
- âSupraventricular tachycardia ââ an abnormally rapid heartbeat originatingsomewhere above the heart’s ventricles, which are the lower chambers.
- âVentricular tachycardia ââ a fast heart rate originating withabnormal electrical signals in the ventricles.
- âVentricular fibrillation ââ when fast, disordered electricalimpulses cause the ventricles to quiver inefficiently instead of pumping bloodthat the body needs.
When To See A Doctor
If you or a loved one notices mild to medium symptoms, go to a doctor quickly.
If you or a loved one faints, has chest pains or trouble breathing, call 911.
Tiredness, trouble concentrating, or breathing harder may just seem like part of growing older. But sometimes itâs more than that.
Be sure to tell your doctor about all your symptoms. If you wear out more easily now than you did a month or year ago, let them know.

Sleep And Coronary Artery Disease
People with obstructive sleep apnea have been shown to have higher rates of coronary artery disease . There are two main reasons why this may occur:
CAD limits the flow of blood due to narrow arteries. This prevents the right amount of oxygen from reaching the heart. Sleep apnea also causes the blood oxygen level to drop during pauses in breathing. This leads to a rise in the heart rate and blood pressure. An extra strain is put on the heart. The amount of oxygen sent to the heart decreases at the time when the heart needs more oxygen. Studies have shown that the presence of OSA increases the risk of death from CAD. But if the sleep apnea is treated, death due to CAD is reduced.
When To Go To The Emergency Department For Heart Palpitations
If you are experiencing a medical emergency, please call 911 or seek care at an emergency room.
Most people barely notice their hearts beating. And thats natural. But any noticeable change in the heartbeat should be concerning. Heart palpitations can be a sign of a serious condition, but some heart palpitations are totally normal.
I describe the feeling of heart palpitations as the heart-pounding sensation you get after running up a flight of stairs. But for people with heart palpitations, that feeling could just show up while theyre sitting on the couch.

Sudden Increased Heart Rate
Normally, an adult’s heart beats 60 to 100 times per minute. You may experience an occasional sudden increase in heart rate that resolves within a few minutes. This is known as a heart palpitation, and it is usually not harmful. If your palpitations are persistent, recurring or if they happen along with other symptoms, you should see your doctor promptly.
Other Causes Of Elevated Heart Rate
Elevated heart rate when sick is actually your heart’s aid in order to quell the sickness. However, there can be other causes as well. Electrical signals produced and sent to the heart tissues are responsible for controlling the heart rate. The occurrence of tachycardia is a result of abnormal heart behavior which causes the heart to produce and send electrical signals at a more rapid rate.
Many things can contribute to malfunction in the heart’s electrical system. For example:
- Heart disease that damage heart tissues
- Sudden stress, such as a fright
- Disease or congenital abnormality of the heart
- High blood pressure
- Excessive alcohol or caffeinated beverages consumption
- Abuse of recreational drugs, such as cocaine

Increase In Resting Heart Rate Is A Signal Worth Watching
- By Howard E. LeWine, MD, Chief Medical Editor, Harvard Health Publishing
When you sit quietly, your heart slips into the slower, steady pace known as your resting heart rate. An increase in your resting heart rate over time may be a signal of heart trouble ahead.
Your heart rate changes from minute to minute. It depends on whether you are standing up or lying down, moving around or sitting still, stressed or relaxed. Your resting heart rate, though, tends to be stable from day to day. The usual range for resting heart rate is anywhere between 60 and 90 beats per minute. Above 90 is considered high.
Many factors influence your resting heart rate. Genes play a role. Aging tends to speed it up. Regular exercise tends to slow your heart rate down. Stress, medications, and medical conditions also influence your resting heart rate.
Results of observational research studies support a link between health and heart rate. Researchers from Norway previously reported the results of a large study looking at changes in resting heart rate over 10 years. They recruited more than 29,000 people without any history or heart disease, high blood pressure, or any other type of cardiovascular disorder, and measured their resting heart rates when they started the study and again 10 years later. This study was published in the Journal of the American Medical Association.

Things You Can Do To Help With Supraventricular Tachycardia
If your episodes of SVT only last a few minutes and do not bother you, you may not need treatment.
You can make changes to your lifestyle to reduce your chances of having episodes, such as:
- cutting down on the amount of caffeine or alcohol you drink
- stopping or cutting back on smoking
- making sure you get enough rest
Your doctor may also be able to recommend some simple techniques to help stop episodes when they happen.
Iii The Effects Of Heart Disease On Sleep
Heart disease can affect your ability to sleep in subtle ways. People with congestive heart failure often have a hard time falling asleep or staying asleep. This is due to the shortness of breath that is caused by CHF. This shortness of breath is often made worse when you lie down. The blood in your legs flows back into the heart. This can bring the heart more blood than it is able to pump.
People who have these symptoms may feel like they have insomnia. Doctors call these symptoms:
- Paroxysmal nocturnal dyspnea
Heart disease also causes people to worry about their health. They are often afraid that they might have a heart attack or stroke. This anxiety can make it very hard to sleep at night. Over time, this sleep problem can develop into chronic insomnia.
