[Disorders of heart rhythm during bicycle ergometry in ischemic heart disease]
Insights
Cardiac rhythm disorders are common in ischemic heart disease patients, particularly those with coronary artery stenosis and impaired left ventricular function. Ventricular extrasystole can be an isolated indicator of myocardial ischemia.
Area of Science:
- Cardiology
- Clinical Medicine
Background:
- Ischemic heart disease (IHD) is a leading cause of mortality worldwide.
- Cardiac rhythm disorders are a known complication of IHD.
Abstract:
During a test on a bicycle ergometer disorders of cardiac rhythm were revealed in 41 (20.5%) out of 240 patients with ischemic heart disease who underwent coronary arteriography. It is concluded that disorders of cardiac rhythm are mostly encountered in patients with ischemic heart disease attended by stenosing changes of the coronary arteries and disorders of left ventricular contractile function as demonstrated by ventriculography. In a few cases ventricular extrasystole may be the only sign of myocardial ischemia in patients with ischemic heart disease.
