[Circadian variations in the frequency of arrhythmia and quantitative analysis of rhythm disturbances]
Abstract:
In 29 patients with long term ECG monitoring the circadian rhythm of extrasystoles was investigated. A decrease of maximal frequency of extrasystoles was calculated for each hour and an increase of the minima during night was detected. In 77% of the patients also for 6 hour-segments a circadian rhythm could be calculated. The effect of the antiarrhythmic treatment on the frequency of extrasystoles was different depending on the frequency of the sinus rhythm.
