bradyarrhythmia
Pronunciation: BRAD-ee-ah-RITH-mee-ah
Any abnormal heart rhythm with a rate below 60 beats per minute that may compromise cardiac output.
Full Definition
Bradyarrhythmia encompasses various abnormal heart rhythms characterized by slow heart rates, typically below 60 beats per minute. These can include sinus bradycardia, heart blocks of varying degrees, and junctional rhythms. In emergency cardiology, bradyarrhythmias are significant when they cause hemodynamic compromise, leading to symptoms such as syncope, hypotension, or altered mental status. Treatment may range from observation to temporary or permanent pacing, depending on the underlying cause and clinical presentation.
Usage
Usage note: Distinguish from simple bradycardia, which refers only to rate; bradyarrhythmia implies abnormal rhythm.
