我院使用多导生理记录仪,经食道直接记录心室晚电位,取得初步成果。 材料和方法 一、病例选择:本院近期住院病人17例(男15例,女2例)。病种分布:心肌梗塞8例,心绞痛3例,房性心律失常2例,心肌病2例,非心脏病患者2例。心肌梗塞8例均伴有室性心律失常。(室性早搏3例,室性心动过速5例)。患者年龄69岁～25岁,平均47.3岁。 Our hospital using multi-channel physiological recorder, trans-esophageal direct recording of ventricular late potential, and achieved initial results. Materials and methods First, the choice of cases: hospital recent inpatient 17 cases (15 males and 2 females). Disease distribution: 8 cases of myocardial infarction, angina in 3 cases, 2 cases of atrial arrhythmia, cardiomyopathy in 2 cases, non-heart disease in 2 cases. Myocardial infarction in 8 cases were associated with ventricular arrhythmias. (3 cases of ventricular premature beats, 5 cases of ventricular tachycardia). Patients aged 69 years to 25 years, an average of 47.3 years old.
