房性早搏(简称房早)位于前一心动的ST段上尚能下传者比较少见,而同时伴有折返途径内的逆转型文氏现象和房室传导中的干扰性文氏现象者更为少见,现报告一例如下。临床及心电图资料患者女性,46岁,临床诊断:风湿性心脏病,二尖瓣狭窄,心功能I-II级。因出现早搏而描记心电图,次日早搏即自行消失。附图为连续描记的II导联.基本心律为窦性,频率为92—109次/分.P波顶峰平坦,略有切迹,似
Atrial premature beats (referred to as room early) is located in the heart of the previous ST segment can still be less than those who can be downloaded, but at the same time with the reversing pathways within the reversal of Wen’s phenomenon and atrioventricular conduction in the phenomenon of disturbing Wen’s more For rare, a report is as follows. Clinical and ECG data Patients Female, 46 years old, clinical diagnosis: rheumatic heart disease, mitral stenosis, cardiac function I-II level. Echocardiogram due to premature beats appear, the next day the spontaneous premature beat disappear. The figure for the continuous tracing of the lead II.The basic rhythm of sinus, the frequency of 92-109 beats / min.P wave peak is flat, slightly notch, may resemble
