心前区病理性Q波的标测,可能为判断前壁心肌梗塞病人室壁坏死的实际范围提供一种较精确的非侵入性评价方法。为了检验这一观念的确实性,联系左室血液动力学及造影检查,进行对比研究。方法:48例经临床、心电图及造影证实的前壁心肌梗塞病人,在心插管术后24小时内,以35个心前区电极标测病理性Q波(≥0.04秒)总数,称作Q波指数。所有病例均
The mapping of pathological Q wave in precordial area may provide a more accurate and non-invasive evaluation method for judging the actual range of ventricular wall necrosis in patients with anterior myocardial infarction. In order to test the validity of this concept, contact left ventricular hemodynamics and contrast examination, comparative study. Methods: Forty-eight patients with anterior myocardial infarction confirmed by clinical, electrocardiogram and angiography were enrolled in this study. The total number of pathological Q wave (≥0.04 seconds) was measured by 35 anterior regional electrodes within 24 hours after cardiac catheterization. Wave index. All cases are
