目的探讨阵发性室上性心动过速(PSVT)发作时伴发胸痛或/和心电图改变的临床意义。方法回顾分析发作PSVT时存在胸痛或/和心电图的ST-T改变的患者17例。男性14人,女性3人,年龄为(55.6±16.2)岁(52～79岁)。行射频消融术(RFCA)同时给予冠状动脉造影(CAG)检查。结果先予CAG 16例,先予RFCA1例。17例中CAG成功率100%,4例患者发现血管病变,仅1例狭窄大于50%;17例RFCA成功率100%,其中旁道者7例,双径者10例,无一例出现严重并发症。结论老年伴有冠心病危险因素的PSVT患者易出现伴发表现,存在伴发表现者冠状动脉造影阳性率很低,对是否存在冠脉病变预测价值不大;RFCA联合CAG可以局麻下一次性完成,手术安全,无并发症。
Objective To investigate the clinical significance of chest pain and / or electrocardiogram (ECG) changes in episodes of paroxysmal supraventricular tachycardia (PSVT). Methods 17 patients with chest pain and / or ST-T changes in electrocardiogram were retrospectively analyzed. 14 males and 3 females, with an age of (55.6 ± 16.2) years (52-79 years). Radiofrequency ablation (RFCA) was given concurrent coronary angiography (CAG). Results CAG 16 cases first, give RFCA 1 case. In 17 cases, the success rate of CAG was 100%. In 4 cases, vascular lesion was found, only 1 case had stenosis greater than 50%. The success rate of RFCA in 17 cases was 100%, including 7 cases of bypass and 10 cases of double diameter. disease. Conclusions PSVT patients with risk factors of coronary heart disease in the elderly are prone to have concurrent manifestations. There is a low positive rate of coronary angiography in those with accompanying manifestations, and the value of predicting the presence or absence of coronary artery lesion is not significant. RFCA combined with CAG can be administered once under local anesthesia Complete, safe operation, no complications.
