动态心电图对心肌缺血诊断的评价

AMBULATORY ECG IN THE DIAGNOSIS OF MYOCARDIAL ISCHEMIA

76例经核素心室造影证实有室壁运动异常的心绞痛患者,进行24h动态心电图检查。结果58例有缺血型ST段异常(76.3%),22例有三级以上室性早搏(28.9%),室壁运动异常区域多者ST段异常发生率、频率、持续时间及偏移程度均较大,室早检出率也明显增高。EF正常组和异常组之间ST段缺血性异常发生率也有显著差异。

Twenty-four hour ambulatory ECG monitoring was used in 76 patients with angina pectoris and abnormal regional wall motion documented by radionuclide. The results showed ST segment abnormality in 58 (76.3%) and severe ventricular arrhythmias in 22 patients (28.9%). In patients with multiple wall motion abnormalities, severer abnormal changes of ST segment in frequency, duration and magnitude with more occurrence of ventricular arrhythmias were found.
