The most common cause of bradycardia is a malfunction in your heart’s natural pacemaker, the sinus node. It controls how quickly the top and bottom heart chambers pump blood through the body. AV ...
If you have bradycardia, your heart beats fewer than 60 times a minute. Bradycardia can be a serious problem if the heart rate is very slow and the heart can't pump enough oxygen-rich blood to the body. If this happens, you may feel dizzy, very tired or weak, and short of breath. Sometimes bradycardia doesn't cause symptoms or complications.
Overview. An example of bradycardia on an electrocardiogram. What is bradycardia? Bradycardia is a condition where your heart beats fewer than 60 times per minute, which is unusually slow. This condition may be dangerous if it keeps your heart from pumping enough blood to meet your body's needs.
Is your resting heart rate slower than normal? If it is too slow, then it could be a heart rhythm disturbance called bradycardia.
A heart rate that’s too slow can cause insufficient blood flow to the brain. Symptoms of bradycardia include: Fatigue or feeling weak. Dizziness or lightheadedness. Confusion. Fainting (or near-fainting) Shortness of breath. Tiring easily during exercise. Chest pain. Complications of bradycardia.
A heart rate below 60 beats per minute, called bradycardia, is fairly common in people older than 70. People experiencing a low heart rate and symptoms such as feeling dizzy, lightheaded, fatigued, or breathless should seek medical care right away.
Causes of Low Heart Rate. How to Check Your Pulse. Treatment. A low resting heart rate, also known as bradycardia, might or might not be a cause for concern. A heart rate below 60 beats per minute (bpm) is typically considered low, but that doesn’t always mean there’s a problem.
Bradycardia is a type of cardiac arrhythmia where your heart rate is below the healthy average. Specifically, this condition applies to a resting heart rate below 60 bpm. A resting rate below 40 bpm is often considered a threshold for severe bradycardia.
Unchecked and untreated, severe or prolonged bradycardia can cause a number of complications including heart failure, low blood pressure, or hypotension, and high blood pressure,...
