本文将乌头碱注入犬(22只)心肌内诱发室速,在乌头碱注射点及周围诸点描记心外膜电图。初步证明室速的心外膜电图在乌头碱注射点呈QS波,在外周诸点呈rS(或Rs)波。说明室速发生部位的心外膜电图以QS波为特征。因为连续室早可构成室速,因此上述规律也适用于室性早搏。而且发现结扎犬冠脉前降支诱发室性早搏,其心外膜电图的QS波发生在心肌缺血区。临床21例频发室性早搏病人的胸前导联电图分析表明,15例室早在右侧胸壁上呈QS波;另6例室早在左侧胸壁上呈QS波,皆有器质性病变。 In this paper, aconitine injected into dogs (22) induced ventricular tachycardia in the aconitine injection points and around the epicardial electrogram. Preliminary evidence of ventricular epicardiac electrocardiogram in the aconitine injection point was QS wave, rS (or Rs) waves in the periphery of the points. Description epicardial ventricular tachycardia electrocardiogram to QS wave characteristics. Because of the early successor to ventricular tachycardia, the above rules also apply to premature ventricular contractions. And found ligation of canine anterior descending coronary artery premature ventricular contractions, the epicardial QS wave occurred in the ischemic area. Clinical 21 cases of frequent premature ventricular contractions in chest lead electrogram analysis showed that 15 cases as early as the QS wave in the right chest wall; the other 6 cases as early as QS wave on the left chest wall, all organic Lesions.
