Common Causes
Bradycardia: Slow Heart Rate. Bradycardia is a heart rate that’s too slow. What’s considered too slow can depend on your age and physical condition. Elderly people, for example, are more prone to bradycardia. In general, for adults, a resting heart rate of fewer than 60 beats per minute (BPM) qualifies as bradycardia. But there are exceptions.

Doctors consider a low heart rate to be 60 beats per minute (bpm) and below. In fact, if you have bradycardia, you’ll have a low resting heart rate below 60, even when you’re awake and active. In contrast, a normal range is 60 to 100 bpm while awake.
What is considered a slow heart rate?
Your heart rate may fall below 60 BPM during deep sleep. And physically active adults (and athletes) often have a resting heart rate slower than 60 BPM. View an animation of bradycardia. Causes for bradycardia include: Problems with the sinoatrial (SA) node, sometimes called the heart’s natural pacemaker
What is considered a low resting heart rate?
What is abnormal heart rhythm? There are many kinds of abnormal heart rhythms, which are collectively known as arrhythmias. One of the most common is abnormally slow heartbeats, a condition known as bradycardia.
What does it mean when your heart rate falls below 60 bpm?
What is abnormal heart rhythm?
What does a low resting heart rate mean?
While a low resting heart rate often suggests greater physical fitness, some situations can make your RHR too low, which may cause occasional dizziness or fatigue. "This may be the result of the electrical nodes of the heart aging, or not transmitting electrical signals correctly," says Dr.
What is bradycardia vs tachycardia?
Tachycardia (tak-ih-KAHR-dee-uh) is a fast heart. The resting heart rate is greater than 100 beats a minute. Bradycardia (brad-e-KAHR-dee-uh) is a slow heartbeat. The resting heart rate is less than 60 beats a minute.
What is another name for a slow pulse?
Bradycardia is a slow or irregular heart rhythm, usually fewer than 60 beats per minute.
What causes a slow heart rate?
The most common cause for bradycardia is a malfunction in the heart's natural pacemaker, the sinus node. It controls how quickly the top and bottom heart chambers pump blood through the body.
What are the two types of bradycardia?
There are two main types of bradyarrhythmia: sinus node dysfunction and atrioventricular (AV) blocks.
What means tachycardia?
Tachycardia refers to a heart rate that's too fast. How that's defined may depend on your age and physical condition. Generally speaking, for adults, a heart rate of more than 100 beats per minute (BPM) is considered too fast.
What is the lowest resting heart rate?
The lowest resting heart beat on record is 27 bpm belonging to Martin Brady (UK, b. 24 March 1969) who was tested at the Guernsey Chest and Heart Unit, Channel Islands on 11 August 2005.
Is bradycardia an arrhythmia?
What is bradycardia? Bradycardia is a type of abnormal heart rhythm, or arrhythmia. It occurs when the heart beats very slowly — less than 60 beats per minute.
What affects your resting heart rate?
Be aware of the factors that can affect your heart rate. Other factors that affect your resting heart rate are: air temperature (high temps and humidity can increase pulse), body position (BPMs can go up right when you stand up), and medication, such as beta blockers that block adrenaline and can slow the pulse.
What is a low resting heart rate for an athlete?
An athlete's resting heart rate may be considered low when compared to the general population. A young, healthy athlete may have a heart rate of 30 to 40 bpm. That's likely because exercise strengthens the heart muscle. It allows it to pump a greater amount of blood with each heartbeat.
What are the symptoms of slow heart rate?
Consult your doctor if you are experiencing some of these symptoms and you have an associated slow heart rate: Lack of energy. Low stamina.
What happens if your heart rate drops to 30?
If your heart rate drops into the 30s, you might not get enough oxygen to your brain, making fainting, lightheadedness, and shortness of breath possible. Blood can also pool in your heart chambers, causing congestive heart failure.
Why does bradycardia happen?
The most common cause for bradycardia is a malfunction in the heart’s 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 ( AV Block ), in which the top and bottom chambers don’t communicate well and the heart rate drops as a result.
How low should your heart beat when you are awake?
Doctors consider a heart rate below 60 beats per minute as low, Dr. Baez-Escudero says. If you have bradycardia, you’ll have a sustained heart rate below 60 even when you’re awake and active. A normal range is from 60 to 100 beats-per-minute while awake.
What age is the most likely to develop bradycardia?
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.
Is bradycardia a problem?
A low heart rate, called bradycardia, occurs frequently in older adults, cardiologist Jose Baez-Escudero, MD, says. It’s not always a problem, but it does require treatment in some cases. “As people get older, there is occasional normal wear and tear on the electrical system of the heart,” he says.
Is a 60 heart rate good?
For most young people, highly trained athletes, and people who exercise regularly, a below-60 heart rate is normal and healthy. It is very possible to have a slow heart rate and experience no symptoms. However, if you have symptoms but ignore them, it can sometimes cause more serious problems.
What is the term for a patient's heart rate to be abnormally slow?
an abnormally slow resting heart rate is described as. bradycardia. A bacterial infection of the lining or valves of the heart is known as bacterial.
What is a type of cancer in which there is insufficient production of one or more types of blood cells?

What happens when your heart rate is too slow?
An inappropriately slow heart rate results in insufficient blood flow to organs and tissues, which can ultimately lead to malfunction and organ failure. The one organ most affected by lack of oxygen and proper nutrients – particularly glucose – is the brain.
What causes a ventricular node to pump?
From the AV node, these electrical signals travel along special conduction tissues to reach the walls of the ventricles, causing the ventricles to pump. Bradycardia can result from diseases affecting the SA node, the conduction tissues, and the AV node.
How long does a pacemaker battery last?
Typically, most implantable pacemakers have a battery that can last 10 to 15 years.
Why do older people need pacemakers?
Thus, people are more likely to need a pacemaker as they get older, both as part of the aging process and because older patients tend to have additional medical problems that can cause slow heartbeats.
How does a pacemaker work?
A pacemaker can keep track of the heartbeat and generate electrical signals similar to that of the heart when it is operating normally , thus causing it to beat appropriately.
What causes heart blockage?
Heart blocks of various degrees and heart failure can occur when cellular damage (due to high blood pressure and heart attacks) or age-related degeneration of the conduction system causes an impaired transmission of signals down through the heart muscle (myocardium).
