为探讨U波倒置时变化的临床意义 ,对 18例变异型心绞痛发作时一过性U波倒置与 30例伴冠心病的原发性高血压患者的U波倒置特点 ,进行比较观察 ,同时 ,对 12例变异型心绞痛患者症状控制后进行冷加压试验 ,观察血压升高时的U波倒置情况 ,并与心绞痛发作时的一过性U波倒置进行比较。结果发现两者U波倒置的时相明显不同 ,变异型心绞痛患者U波呈正负双相 ,原发性高血压患者则负正双相 ,认为U波倒置的时相变化具有鉴别诊断意义。
In order to explore the clinical significance of the U wave inversion, the echocardiographic U-wave inversion of 18 patients with variant angina pectoris and 30 patients with essential hypertension with essential hypertension were compared and observed. At the same time, Twelve patients with variant angina pectoris were subjected to cold compression test after symptoms were controlled, and the U wave inversion was observed when the blood pressure was elevated. The U wave inversion was compared with the transient U wave inversion at the onset of angina pectoris. The results showed that the phases of U wave inversion were significantly different between the two groups. U wave in patients with variant angina presented positive and negative biphasic and patients with essential hypertension were negatively biphasic. It was considered that phase inversion of U wave was of differential diagnostic significance.
