1872年Traube首先介绍脉交替(alte-rans of pulses),指的是正常起搏点发出的规则的心脏搏动,其脉搏为强弱交替。后来Lewwis指出这种交替性搏动可见于心房、左室和右室,并且有R-R间期的长短交替。1908年Hering又提出了电活动的交替(alternative electrical activity)。随着心电图技术的发展,发现了心房的P波和心室QRS波电交替活动。后又发现不少患者出现脉交替的同时,有心电图的电交替。显然,心脏的交替性活动应包括机械性强弱和

Traube first introduced the alte-rans of pulses in 1872, referring to the regular heartbeat pulsations emanating from normal pacemakers whose pulses alternated between strength and weakness. Later Lewwis pointed out that such alternating beats can be seen in the atria, left ventricle and right ventricle, and there is an alternation of the length of the R-R interval. In 1908 Hering proposed alternative electrical activity. With the development of ECG technology, it was found that the atrial P wave and ventricular QRS wave alternating activity. Later found that many patients appear alternating veins at the same time, there is electrocardiogram alternating electricity. Obviously, alternating heart activity should include mechanical strength and
