ventricular arrhythmia
Pronunciation: ven-TRIK-yoo-lar ar-RITH-mee-ah
Abnormal heart rhythm originating from the ventricles, potentially life-threatening during exercise.
Full Definition
Irregular heart rhythms that arise from the ventricles, including premature ventricular contractions, ventricular tachycardia, and ventricular fibrillation. In cardiac rehabilitation settings, ventricular arrhythmias may indicate exercise intolerance, ischemia, or electrolyte imbalances requiring immediate attention. Exercise protocols include specific monitoring guidelines and termination criteria when ventricular arrhythmias occur during training sessions.
Usage
Usage note: Distinguish from atrial arrhythmias; requires different monitoring and response protocols.
In Context
- "Exercise was immediately terminated when ventricular arrhythmia appeared on the monitor." — Emergency response
- "The patient's history of ventricular arrhythmia required continuous ECG monitoring during exercise." — Safety protocol
