| 摘 要： | 目的比较公式计算出的左室射血分数(LVEF)与超声心动图LVEF的结果,探讨不稳定型心绞痛患者心电图判断射血分数的作用,并进行危险分层。方法2003年1月至2004年12月住院的不稳定型心绞痛患者65例,扩张型心肌病患者66例,对照组为我院行射频消融术的阵发性室上性心动过速患者69例,根据入院时心电图,采用公式LVEF=β1aVR(R波和S波振幅之和,mV)+β2年龄(β1=0.264,β2=0.645),计算LVEF值并与其超声心动图LVEF进行比较。三组患者年龄与性别之间无统计学差异。结果不稳定型心绞痛组患者公式计算的LVEF与超声心动图LVEF无统计学差异,而扩张型心肌病组,二者有显著差异,有统计学意义(p<0.01)。结论应用公式LVEF=β1aVR(R波和S波振幅之和,mV)+β2年龄(β1=0.264,β2=0.645),从体表心电图计算LVEF,早期评估不稳定型心绞痛或NSTEMI患者的心功能状态,并进行危险分层,力争短时间内进行冠脉血运重建治疗,使患者获益最大。

| Abstract: | Objective To compare LVEF derived from Electrocardiogram (ECC)with LVEF measured frome-chocardiography (UCG). Methods A retrospective study was done to compare LVEF from ECG and UCG in 65 patients with unstable angina and 66 patients with idiopathic dilated myocardiopathy, 69 patients with parosysmal supraventricular tachycardia(PSVT). Results LVEF values between ECG measurements and echocardiography showed significant difference in DCM dilated myocardiopathy) group, there is no significant difference in un... |
