| idioventricular rhythm | A slow independent ventricular rhythm under control of a ventricular centre (which is, by definition, ectopic). Synonym: ventricular rhythm. (05 Mar 2000) |
| accelerated idioventricular rhythm | A transient and intermittent type of arrhythmia with episodes lasting from a few seconds to a minute which usually occurs in patients with acute myocardial infarction or with digitalis toxicity. Suppressive therapy is rarely necessary because the ventricular rate is generally less than 100 beats per minute. (12 Dec 1998) |
