患者男性,54岁,长期患冠心病伴室壁瘤。图1为室壁瘤切除前所描记的心电图。示窦性心律伴室性早搏二联律,P-R 间期0.16秒,左房肥大,窦性下传的QRS 波宽大畸形,时限宽达0.16秒,平均额面电轴-150°, 左侧导联(I、aVL、V_4—V_6)QRS 波群主波向下,右胸导联QRS 波群主波向上。左胸导联有深宽的Q 波,QS 波有切迹。额面和横面向量表明窦性下传QRS 波群的除极向量是从左向右。每个窦性激动后均有来自左后的室性早搏形成二联律。早搏的QRS 间期为0.15″,平均(?)面电轴为-90°,右胸前导联QRS 波群主波向上,呈右束支阻滞型。
Male patient, 54 years old, with long-term coronary heart disease with aneurysm. Figure 1 is the electrocardiogram described before the resection of the aneurysm. Show sinus rhythm with premature ventricular premature beats, PR interval of 0.16 seconds, left atrial hypertrophy, sinus QRS wave large deformity, the time width of 0.16 seconds, the average frontal axis -150 °, the left guide Associated (I, aVL, V_4-V_6) QRS wave group down, the right chest lead QRS wave group up wave. Left chest lead has a wide Q wave, QS wave notch. Frontal and transverse vectors indicate that the depolarizing vector of sinusoidally transmitted QRS complex is from left to right. Ventricular premature beats from the left posteriorly form a bicombo after each sinus surge. The QRS interval of premature beats was 0.15 ", and the average (?) Plane electrical axis was -90 °. The main wave of the right anterior thoracic leads QRS wave group was upward with a right bundle branch block.
