[Antiarrhythmic properties of angiotensin converting enzyme inhibitors]

In animal experimental models angiotensin converting enzyme (ACE) inhibitors have been found to reduce arrhythmias. In patients with cardiovascular disorders treated with ACE inhibitors the reduction of incidence and the severity of arrhythmias as well as the decrease mortality have been observed. There is little evidence to prove that ACE inhibitors affect directly the electrophysiological function of a heart. It seems that antiarrhythmic effects of ACE inhibitors are indirect.
