Does Slow Heart Rate Mean Clogged Arteries

Low Heart Rate – Causes, Symptoms, Dangers

Experts are rediscovering that faster resting heart rates are linked to the development of cholesterol-clogged coronary arteries, chest pain, and shorter lives. This new attention is sparked, in part, by new drugs that slow the heart rate. You neednt and shouldnt wait for them.

Exercise And Your Pulse

If you check your pulse during or immediately after exercise, it may give an indication of your fitness level. A heart rate monitor is also useful for recording your heart rate when resting and during exercise.

Aerobic activities such as walking, running and swimming are good types of exercise because they increase your heart and breathing rates.

If you haven’t exercised before, or haven’t for some time, see our Live Well section to read about the benefits of exercise and how much exercise you should be doing.

Heart Rates And Risk Factors

Heart rates determine our heart healths status. A high heart rate means that our heart might be pumping too much blood and a low heart rate means that it might be pumping less. Whichever the case, both instances may be dangerous to our overall health. However, a low heart rate is slightly more worrying than a high heart rate. You can experience a high heart rate by exercising or getting excited. It means that when your heart is pumping blood too fast, it is more likely to be a natural occurrence. On the other hand, a low-heart rate may have negative implications. Well talk about the risk factors, symptoms, and treatment of a dangerously low heart rate in this article. But before we dive into the details, we highly suggest calling your doctor in a case like this. They are always the best individuals to contact about heart problems.

Measuring Your Heart Rate

Checking your resting heart rate isnt difficult. Start by sitting quietly for five minutes or so. Then, place two fingers on the thumb side of your wrist, between the bone and the tendon over your radial artery. Once you feel a pulse, count the number of beats for 15 seconds. Then multiply that number by four. That will give you your beats per minute.

Its a good idea to do this every so often, just to have a baseline number. If you notice a changeup or downtell your doctor at your next appointment. You should also talk with your doctor about your target heart rate, particularly if you are an older adult or you have risk factor for cardiovascular problems, such as diabetes, family history of heart disease, smoking, obesity, a sedentary lifestyle, or high blood pressure.

Keep in mind that your heart rate should go up when you exercise and then return to a normal resting heart rate soon after you stop. If your heart rate doesnt rise very much or takes a long time to return to normal, tell your doctor. It may be a sign of a heart that isnt working optimally. It may not be serious, but it is worth a discussion with your physician.

What’s A Normal Heart Rate

Heart Rate Training: Everything You Need To Know

Most adults have a resting heart rate between 60 and 100bpm.

The fitter you are, the lower your resting heart rate is likely to be. For example, athletes may have a resting heart rate of 40 to 60bpm, or lower.

See a GP to get checked if you think your heart rate is continuously above 120bpm or below 40bpm, although it may simply be that this is normal for you.

Health risks can develop from a low heart ratea condition called bradycardia.

A low heart rate may be a sign of an efficiently working heart. Or, if the rate becomes too low, it could be a sign of health complications down the road.

A normal or healthy resting heart rate for an adult is between 60 and 100 beats a minute. A heart rate near the lower end of that range is considered a good sign. Your heart isnt working too hard to pump blood effectively throughout the body. Its one indication of cardiovascular fitness. A very rapid heart rate, on the other hand, raises your risk of heart failure, blood clots, and other problems.

If youre not training for a marathon or swimming dozens of laps every day, you should talk with your doctor if you notice a low heart rate.

How Is Bradycardia Diagnosed

Your healthcare provider will ask about your symptoms. Tell him or her when they started and how often they happen. Tell him or her how severe your symptoms usually are, and how long they last. He or she will ask what triggers your symptoms and if anything makes them worse or better. He or she may ask if you have a heart condition or take any medicines. Tell your provider if symptoms happen after you take certain medicines. Tell him or her if you have a family history of heart conditions. You may also need any of the following:

Normal Resting Heart Rate For Kids

Is a Low Heart Rate Dangerous?

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.

Case Report: Remdesivir Induced Dangerously Low Heart Rate In Covid

Prompt recognition of remdesivir-induced hemodynamically unstable sinus bradycardia is crucial during treatment of COVID-19, doctors advise in Heart Rhythm Case Reports

Philadelphia, June 24, 2021 After beginning treatment with remdesivir for COVID-19, a patient experienced significant bradycardia, or low heart rate. Her physicians used a dopamine infusion to stabilize her through the five-day course of remdesivir treatment, and her cardiac condition resolved itself at the end of the treatment. The case is discussed in Heart Rhythm Case Reports, an official journal of the Heart Rhythm Society, published by Elsevier.

Remdesivir has become the standard of care for COVID-19 pneumonia and there is a paucity of data on its cardiac effects, explained lead author Jomel Patrick Jacinto, DO, HCA Healthcare/USF Morsani College of Medicine GME Programs at Regional Medical Center Bayonet Point, Hudson, FL, USA. While it is known to be well tolerated and effective, its critical to note its potential adverse effects on the cardiovascular system. To our knowledge, this is the first reported case of remdesivir-induced hemodynamically unstable sinus bradycardia.

What Causes Or Increases My Risk For Bradycardia

  • Heart damage caused by a heart attack or heart disease
  • A condition such as amyloidosis or hemochromatosis
  • Problems with your heart node
  • Conditions that affect how electrical signals travel between atria and ventricles and cause your heart to beat
  • Sleep apnea
  • Certain infections, such as Lyme disease, diphtheria, or endocarditis
  • Hypothermia , or health problems that cause low oxygen levels
  • Low thyroid hormone levels, low blood sugar levels, or electrolyte balance problems
  • Certain medicines, such as heart or hypertension medicines and some antidepressants
  • Age older than 70

Why Could A Low Heart Rate Be Bad In Some Situations

The heart needs to pump out a certain amount of blood to provide the body with the blood it needs to function. The amount of blood pumped is known as cardiac output and is usually defined as liters per minute. Heart rate of course affects this output. In some patients a low heart rate can lead to a low output and cause symptoms such as dizziness, shortness of breath and fatigue. These symptoms are associated with low output heart failure. In other patients a low heart rate causes no effect whatsoever as the heart simply pumps out more blood with each beat to compensate.

What Is Bradycardia How To Know If Your Heart Rate Is Too Low

Can A Low Heart Rate Make You Tired?
  • Bradycardia is when your resting heart rate is slower than normal.
  • Well-trained athletes can have a resting heart rate as low as 40 or 50 bpm, and when caused by exercise, bradycardia is considered healthy.
  • However, for others with a resting heart rate this low, bradycardia can be dangerous and should be checked out by a doctor.
  • This article was reviewed by John Osborne, MD, PhD, and the Director of Cardiology for Dallas-based State of the Heart Cardiology.
  • This story is part of Insider’s guide to Heart Disease.

Bradycardia, or a heart rate that is too slow, can be a serious condition, especially if the heart is not pumping enough oxygen-rich blood throughout the body.

Here’s what medical experts consider to be a low heart rate, how to know if you have bradycardia, and the most common ways to treat it.

What Is The Heart Rate

Heart rate or pulse rate is the number of times your heart beats in a minute. It is a simple measure to know how much your heart works during rest or activities.

Heart rate is one of the vital signs that are checked regularly whenever you visit your doctor, or when you get admitted to the hospital.

Your heart rate is lower when you are resting and higher when you are doing any kind of activity, or are feeling stressed or anxious.

When you exercise, your heart needs to work harder, which increases your heart rate. As soon as you rest, the heart rate starts decreasing gradually and returns to its normal level, usually within an hour.

What Heart Rate Is Too High

Generally, for adults, a heart rate of more than 100 beats per minute is considered as high.

Your heart rate usually rises when you walk fast, run, or do any strenuous physical activities.

Maximum heart rate and Target Heart Rate

Before doing any vigorous exercise, you should know your maximum heart rate and target heart rate, both of which vary by age.

Going beyond your maximum heart rate is not healthy for you. Your maximum heart rate depends on your age. This is how you can calculate it:

  • Subtracting your age from the number 220 will give you your maximum heart rate. Suppose your age is 35 years, your maximum heart rate is 185 beats per minute. If your heart rate exceeds 185 beats per minute during exercise, it is dangerous for you.
  • Your target heart rate zone is the range of heart rate that you should aim for if you want to become physically fit. It is calculated as 60 to 80 percent of your maximum heart rate.
  • Your target heart rate helps you to know if you are exercising at the right intensity.
  • It is always better to consult your doctor before starting any vigorous exercise. This is especially important if you have diabetes, heart disease, or you are a smoker. Your doctor might advise you to lower your target heart rate by 50 percent or more.

Given below are the table showing the target heart rate zone and maximum heart rate as per age.
