我们对器质性心脏病218例和正常人99例在常规休息时心电图上出现之室早作了比较,出现下列情况者,两组间具有十分显著的统计学意义(P<0.01): 1.室早起源于左室,室早的QRS时间≥0.16秒,QRS电压≤10毫伏,QRS顶端粗钝切迹;2.室早以Q波起始者,仅见于病人组(16.1%);3.室早伴Ptf-V_1≤-0.03毫米·秒者仅见于病人组(45.5%);4.连
We have 218 cases of organic heart disease and normal 99 cases of normal resting electrocardiogram appeared in the room earlier made the following cases, the two groups was statistically significant (P <0.01): 1 .Survival originated in the left ventricular early, QRS time ≥0.16 seconds, QRS voltage ≤10 millivolts, QRS apical blunt notch.2.As early as Q-waves in the ventricle, only seen in the patient group (16.1%), ; 3. Room early with Ptf-V_1≤-0.03mm · sec were only seen in the patient group (45.5%); 4. Even
