A number of investigations indicate that faster resting heart rate has emerged as a new risk factor for mortality in homeothermic mammals, particularly cardiovascular mortality in human beings. Faster heart rate may accompany increased production of inflammation molecules and increased production of reactive oxygen species in cardiovascular system, in addition to increased mechanical stress to the heart. There is a correlation between increased resting rate and cardiovascular risk. This is not seen to be “using an allotment of heart beats” but rather an increased risk to the system from the increased rate.
Given these data, heart rate should be considered in the assessment of cardiovascular risk, even in apparently healthy individuals. Heart rate has many advantages as a clinical parameter: It is inexpensive and quick to measure and is easily understandable. Although the accepted limits of heart rate are between 60 and 100 beats per minute, this was based for convenience on the scale of the squares on electrocardiogram paper a better definition of normal sinus heart rate may be between 50 and 90 beats per minute.
What Is Considered A Dangerously High Heart Rate
A normal heart rate in a healthy adult range from 60 to 80 beats per minute at rest, Infants and children has higher heart rates than adults in the normal state. The heart rate can rise during exercise, running, high fever, flu, excitement, consumption of nicotine or caffeine, surgical operations, and treatment procedures. When heart rate in adults exceeds 100 beats per minute at rest, then the condition is called tachycardia which has a pathological reason behind. It becomes extremely dangerous for the patient as it may cause heart failure, cardiac arrest, and even death.
What Is Considered Severe Bradycardia
When a Slowed Heart Rate Means Serious Trouble In medical textbooks, bradycardia is usually defined as a resting heart rate that is below 60 beats per minute. However, many healthy people have a resting heart rate between 50-60 beats per minute, particularly athletes or sleeping people.

How Serious Is Having An Irregular Heartbeat
While we may say our heart skips a beat when it comes to falling in love. But when your heart literally skips a beat, its known as an arrhythmia.
Day in and day out, you likely dont notice your heartbeat at all, especially if its functioning normally. However, when you experience stress or youre performing strenuous exercise, you may notice a higher heart rate or even sensations of fluttering in your chest.
However, for individuals living with an arrhythmia, feelings and sensations such as this may occur without any exertion or stress at all.
Put simply, arrhythmia is the medical name for an irregular heartbeat, says Shalabh Chandra, MD, an electrophysiologist at Georgia Heart Institute. There are many different forms of arrhythmias that can cause your heart to beat too quickly, too slowly or irregularly.
If youve been diagnosed with an arrhythmia, is it a serious health issue? Dr. Chandra answers that question and provides key insights about this common heart condition below:
Q: What exactly is an arrhythmia?
Dr. Chandra: The hearts electrical system is what coordinates each heartbeat and coordinates the contracting and pumping between its chambers. However, when that system is disrupted or not functioning correctly due to damage, disease or other factors, this can cause your heartbeat to become abnormal.
In some cases, an abnormal heartbeat may be temporary and will come and go or it can be present all the time .
Q: What are the different types of arrhythmia?
Causes Of Low Heart Rate
Firstly we will discuss things directly affecting the heart tissue and the conduction system called intrinsic disease. Aging is a common cause of slow heart rate, which results from degeneration of the conduction system of the heart. Heart attacks may damage areas of the conduction system also. Conditions that affect many organs of the body such as sarcoid, lupus and others can also affect the conduction system of the heart. Undergoing heart valve surgery such as the TAVR procedure for aortic stenosis, the mitraclip procedure for mitral regurgitation, mitral valve replacement or mitral valve repair, aortic valve replacement, or other complex heart surgeries may also cause trauma to the conduction system of the heart. Sometimes infection of the heart valves can extend in to the conduction system of the heart also.
Next we will discuss outside influences on the heart and conduction system known as extrinsic causes. Certain situations such as coughing, vomiting and others can lead to slow heart rate through the nerve system. Drugs that directly slow the heart rate include beta-blockers, calcium channel blockers and others. Metabolic disorders such as hypothyroidism can lead to a slow heart rate. Levels of electrolytes such as potassium derangement can lead to a slow heart rate.
What Your Heart Rate Says About Your Cardiovascular Health
Your heart is responsible for pumping blood and oxygen throughout your body and if youre having heart troubles, the rest of your body will be impacted too.
A higher resting heart rate can be dangerous because it taxes the heart, making it work harder. This is linked to a higher risk of heart disease and death, just like high blood pressure or high cholesterol. Resting heart rates that near or exceed 100 should be brought to the attention of your doctor.
Causes Of Supraventricular Tachycardia
An episode of supraventricular tachycardia occurs when abnormal electrical impulses suddenly start in the upper chambers of the heart, and override the heart’s natural rhythm.
SVT is sometimes called paroxysmal supraventricular tachycardia . Paroxysm means a sudden temporary disturbance of heart rhythm.
PSVT is usually caused by a short circuit in the electrical system of the heart, which causes an electrical signal to travel rapidly and continuously around in a circle, forcing the heart to beat each time it completes the circuit.
Another type of SVT is called Wolff-Parkinson-White syndrome, where an abnormal electrical connection occurs between the atria and ventricles . People with Wolff-Parkinson-White syndrome are born with a strand of extra muscle tissue between these chambers. This produces a short circuit, which causes the fast heartbeat.

What If My Resting Heart Rate Is High Does The Same Formula Still Apply
Even if your resting heart rate is higher, say 90 beats per minute, the same formula still applies to you. What this means, however, is that you have less room to move in terms of reaching your maximum safe heart rate.
Studies show that a resting heart rate of over 84 may be dangerous and having a medical exam is important to ensure that you dont have any underlying issues causing the accelerated rate.
If you have had a higher heart rate your entire life, then it is likely that you simply have a high heart rate, but it is always best to err on the side of caution and get a medical opinion.
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.

What Causes High Pulse Rate
What causes high pulse rate?
Common causes of high pulse rate include:Heart-related conditions such as high blood pressure, the poor blood supply to the heart muscle due to coronary artery disease, heart valve disease, heart failure, heart muscle disease, tumors, or infections.Other medical conditions such as thyroid disease, certain lung diseases, electrolyte imbalance, and alcohol or drug abuse. Emotional stress or drinking large amounts of alcoholic or caffeinated beverages
what causes low blood pressure and high heart rate?
You may be ecstatic that you finally got your blood pressure lowered, only to notice your heart seems to be racing, all the time. So what gives when you successfully hit the magic number of < 120/< 80 mm, but your heart rate remains high? Heart rhythm specialist, says sometimes this is normal and sometimes its not.When is this combo not a big deal?Sometimes blood pressure and high heart rate occur momentarily.However, that phenomenon is short-lived. When the heart rate stays consistently high while blood pressure is low, there may be something problematic going on.
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 To Check Your Heart Rate
You can check your heart rate by counting the pulse. A pulse can be felt at various sites on the body like over the sides of the neck, the wrist, and the top of the foot. To check your pulse on the wrist with the help of your middle finger and index finger, you need to:
- Keep your middle finger and your index finger over the inner part of the wrist and keep pressing gently until you can feel your pulse. The pulse is felt in your radial artery.
- After you have located your pulse, look at the watch, and start counting the beats for 30 seconds. Doubling this count will give you your heart rate. You can even count the beats for 10 seconds and multiply the number by six to get your heart rate.
If you find the rhythm of your heartbeat slightly irregular, you will have to count the beats completely until 60 seconds. You will have to visit your doctor if you keep getting a fast and irregular heart rate consistently.

Hereof, what is a dangerous heart rate?
Tachycardia refers to a fast resting heart rate, usually over 100 beats per minute. Tachycardia can be dangerous, depending on its underlying cause and on how hard the heart has to work. However, tachycardia significantly increases the risk of stroke, sudden cardiac arrest, and death.
Also Know, is a heart rate of 170 dangerous? Tachycardia is a heart rate higher than 100 beats per minute. Ventricular tachycardia starts in the heart’s lower chambers. Most patients who have ventricular tachycardia have a heart rate that is 170 beats per minute or more.
One may also ask, what is a dangerously high heart rate when exercising?
According to their calculations, maximum heart rate is around 220 beats per minute minus the person’s age. Therefore, a 20-year-old’s maximum heart rate would be around 200 bpm .
Is 200 heart rate dangerous?
Some people mostly younger people can easily push their heart rate to over 200 beats per minute, while others already reach their limit with a heart rate of 170. However, this does not reveal anything about whether the person with a maximum heart rate of 220 is fitter than the one with a maximum heart rate of 180.

How Do I Check My Resting Heart Rate
To check your heart rate:
- Sit down and rest for 5 minutes.
- Turn your wrist so your palm is facing up.
- Feel for a pulse at thumb side of your wrist.
- Once you feel it, count how many times you feel a beat in 30 seconds. Then double it.
If you cant find your pulse at your wrist, put 2 fingers on the side of your neck, next to the windpipe.
If you still cant find a pulse, ask someone else to feel it for you.
What Do My Heart Rate Numbers Mean
Your resting heart rate is the number of times your heart beats each minute when youre not active. The normal range is between 50 and 100 beats per minute. If your resting heart rate is above 100, its called tachycardia below 60, and its called bradycardia. Increasingly, experts pin an ideal resting heart rate at between 50 to 70 beats per minute.
If you want to find out your resting heart rate, pick a time when youre not active, find your pulse, count how many times it beats in 30 seconds, and then double that number. You may want to check it several times throughout the day, or over a week, to average out the number and to look for any irregularities.
Resting heart rates can change from person to person and throughout the day, influenced by everything from your mood to your environment. It rises when youre excited or anxious, and sometimes in response to smoking cigarettes or drinking coffee. More athletic people tend to have lower heart rates.

How Slow Is Too Slow
Doctors consider a heart rate below 60 beats per minute as low, Dr. Baez-Escudero says.
If you have bradycardia, youll have a sustained heart rate below 60 even when youre awake and active. A normal range is from 60 to 100 beats-per-minute while awake. The heart rate can also slow down normally while we are asleep to 40 to 60 beats a minute.
What Are Heart Palpitations
A heart palpitation is when you suddenly become aware of your heart beating, usually in an irregular way. Sometimes you can feel it in your ears or your chest when youre lying down. Your heart beat may feel:
- too fast or slow
- like its fluttering
- like its thudding, or pounding.
It is not unusual to feel heart palpitations occasionally and mostly they are harmless. However if youre experiencing them on a regular basis, see your doctor.
