患者,男,77岁。临床诊断为充血性心肌病。1989年6月13日作心电图Ⅱ导联连续记录(附图)。心电图分析Ⅱa、Ⅱc、Ⅱd均可见联律间期相等的高位室性早搏,S波升支隐藏有逆行P波,但回转周期不同。图中可见P波直立和倒置的两种心律,QRS波形态正常,但ST段下移,T波倒置。此两种心律在室性早搏前后互相转换。直立P波节律不齐,频率55～64次/分,P-R间期0.16秒,为窦性心律不齐,长P-P间期和短P-P间期间没有最大公约数,且在房室交界区心律转为窦性心律时有明
Patient, male, 77 years old. Clinical diagnosis of congestive cardiomyopathy. June 13, 1989 for continuous recording of ECG Ⅱ lead (with photos). ECG analysis Ⅱ a, Ⅱ c, Ⅱ d can be seen with the law of the same interval between the high premature ventricular contractions, S wave ascending hiding retrograde P wave, but the rotation cycle is different. P wave can be seen upright and inverted two kinds of rhythm, QRS wave morphology is normal, but the ST segment down, T wave inversion. The two kinds of heart rate before and after premature ventricular contractions conversion. Rhythm P wave irregularly, the frequency of 55 to 64 beats / min, PR interval of 0.16 seconds, sinus arrhythmia, long PP interval and short PP between the greatest common divisor, and in the atrioventricular junction arrhythmia When the sinus rhythm Ming
