dysrhythmia

Pronunciation: dis-RITH-mee-ah

Abnormal heart rhythm, often used interchangeably with arrhythmia in clinical documentation but with subtle editorial distinctions.

Full Definition

An abnormality in the heart's electrical conduction system resulting in irregular, fast, or slow heart rhythms. The term dysrhythmia is often used synonymously with arrhythmia, though some clinicians prefer dysrhythmia to indicate any deviation from normal rhythm. Medical editors encounter this terminology in ECG interpretations, electrophysiology studies, and cardiac monitoring reports. Common types include atrial flutter, ventricular tachycardia, and various forms of heart block. Documentation typically includes specific rhythm identification, hemodynamic significance, and treatment responses. The choice between dysrhythmia and arrhythmia may depend on institutional preference or specific clinical context.

Usage

Usage note: Often interchangeable with arrhythmia; maintain consistency within documents.
