Detailed explanation-1: -Bradycardia (brad-e-KAHR-dee-uh) is a slow heart rate. The hearts of adults at rest usually beat between 60 and 100 times a minute. If you have bradycardia, your heart beats fewer than 60 times a minute.
Detailed explanation-2: -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. A normal heartbeat begins with an electrical impulse from the sinus node, a small area in the heart’s right atrium (right upper chamber).
Detailed explanation-3: -An ECG can show if the heart is beating too slow, too fast or not at all. Because an ECG can’t detect bradycardia unless the slow heartbeat occurs during the test, your health care provider might recommend a portable ECG device.
Detailed explanation-4: -Causes for bradycardia include: Problems with the sinoatrial (SA) node, the heart’s natural pacemaker. Problems in the conduction pathways of the heart that don’t allow electrical impulses to pass properly from the atria to the ventricles. Metabolic problems such as hypothyroidism (low thyroid hormone)
