bradyarrhythmia
Pronunciation: brad-ee-uh-RITH-mee-uh
An abnormally slow heart rhythm, typically below 60 beats per minute, that may require pacemaker intervention.
Full Definition
Bradyarrhythmia refers to any cardiac rhythm disorder characterized by an abnormally slow heart rate, usually defined as less than 60 beats per minute in adults. This condition can result from dysfunction of the sinoatrial node, atrioventricular conduction blocks, or other conduction system abnormalities. Bradyarrhythmias may be symptomatic, causing fatigue, dizziness, or syncope, and often require treatment with pacemaker implantation. The condition is distinct from physiological bradycardia seen in trained athletes.
Usage
Usage note: Distinguish from bradycardia, which refers only to slow heart rate without implying rhythm abnormality.
