患者女性,52岁,发作性心前区不适半年余,X线胸片、超声心动图和血脂检查等均在正常范围,疑有冠心病作葡萄糖负荷试验。服糖前P-P0.86秒左右,P明显直立,QRS-T正常;服葡萄糖100g4分钟后P-QRS-T无明显改变;服糖后60分钟时P-P0.90秒,PⅡ明显变低、PⅢ倒置、PaVF变为平坦,P极性发生改变,QRS-T仍无改变。aVR导联在服糖前后始终倒置,P-R固定不变;至服糖后120分钟仍未恢复至服糖前图形,P-P0.84—0.90秒,仍有P极性改变(附图)。持续至服糖后2小时30分始恢复至服糖
Female patient, 52 years old, episodes of precordial discomfort more than six months, X-ray, echocardiography and blood lipids were in the normal range of examination, suspected coronary heart disease for glucose load test. P-P0.86 seconds before serving the sugar, P was significantly upright, QRS-T normal; taking glucose 100g 4 minutes after P-QRS-T no significant change; 60 minutes after taking sugar P-P0.90 seconds, P Ⅱ significantly change Low, P Ⅲ inversion, PaVF becomes flat, P polarity changes, QRS-T still no change. The aVR lead was always inverted before and after the oral administration of sugar, and the P-R was unchanged. After 120 minutes of taking the sugar, the aVR lead was still not restored to the figure before serving the sugar. P-P0.84-0.90 seconds, there was still a P-polarity change (with photos). Continue to serve 2 hours and 30 hours after the start of recovery to sugar
