众所周知,左室肥厚(LVH)是主动脉瓣狭窄(AS)常见的心电图改变;然而,主动脉瓣狭窄的心电图变化未很好地与症状、狭窄程度以及无症状患者的预测联系起来。本文分析50例16～65岁经尸检证实主动脉瓣狭窄患者的心电图;其中部分患者伴有主动脉瓣关闭不全。临床和尸检资料:50例平均年龄48岁(16～65岁);男36例,女14例。左室-主动脉收缩期压力阶差峰值平均为98毫米汞柱(范围52～180),主动脉瓣面积(AVA)平均为0.53厘米~2(范围0.16～0.89),心脏指数平均为2.7升/分/米~2(范围1.3～4.7),记录到主动脉瓣关闭不全杂音者24例(48%)。13例作血管造影者,4例显示并有主动脉瓣关闭不全。34例(68%)有心绞痛。所有患者的心功能均大于Ⅲ级。尸解心脏重量平均606克(380～880克)。冠状动脉狭窄>75%并累及1个主支以上者占32%,7例左室有疤痕,仅1例左室呈现肉眼所见的坏死。心电图观察:15例心电图示左房异常,7例 P-
It is well known that left ventricular hypertrophy (LVH) is a common electrocardiographic change in aortic stenosis (AS); however, ECG changes of aortic stenosis are not well linked to symptoms, the degree of stenosis, and the prediction of asymptomatic patients. This article analyzes 50 patients aged 16 to 65 years autopsy confirmed aortic stenosis in patients with ECG; some patients with aortic insufficiency. Clinical and autopsy data: The average age of 50 cases was 48 years old (16-65 years old); 36 males and 14 females. The mean LV systolic pressure gradient peak was 98 mmHg (range, 52-180), aortic valve area (AVA) was 0.53 cm -2 (range, 0.16-0.89), and cardiac index was 2.7 L / Min / m ~ 2 (range 1.3 ~ 4.7), recorded aortic valve regurgitation noise in 24 cases (48%). Thirteen patients underwent angiography and 4 patients showed aortic insufficiency. 34 cases (68%) had angina. All patients had greater than grade III cardiac function. An autopsy heart weight average 606 grams (380 ~ 880 grams). Coronary artery stenosis> 75% and involving more than a major branch accounted for 32%, 7 cases of left ventricular scar, only 1 case of left ventricular necrosis showed naked eye. ECG observation: 15 cases of left atrial anomalies ECG, 7 cases of P-
