摘要
为探讨U波倒置时相变化的临床意义 ,对18例变异型心绞痛发作时的一过性U波倒置与30例不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呈负正双相 。
In order to study clinical significance of phasic chages in inverted U wave was studied by comparing and observing temporary inverted U wave produced by angina pectoris attack in 18 cases of variant angina and inverted U wave in 30 cases of hypertension without CAD.Meanwhile,a comparison was made between inverted U wave during rising BP caused by cool pressor test in 12 cases of variant angina after calcium antagonist therapy resulting in symptomatic relief,and temporary inverted U wave during angina pectoris attack.Results showed significant difference in phasic pattern between two types of inverted U wave,U wave in variant angina presented positive _ negative phase while that of original hypertention presented negative _ positive phase.It suggests that phasic changes in inverted U wave are valuable in differential dignosis.
