摘要
对164例病人进行心脏电生理检查,共检出15例潜在性束支阻滞,其中右束支阻滞11例(73.3％),左束支阻滞2例(13.3％),检出左右束支阻滞2例(13.3％)。对13例右束支有效不应期和4例左束支有效不应期进行了比较,其结果无显著差异。同时又用S_1-S_2及P-S_2二种方法对束支阻滞有效不应期(ERP_(BB))检出结果进行了比较,结果一致,提示二者都是程控刺激,故方法可靠。
Electrocardiophysiological study was made in 164 cases of the patients. Potential bundle branch block was found in 15 cases, 11(78.3%) right bundle branch block,2(13.3%) left bundle branch block and 2(13.3%) bibundle branch block. There was no significant difference between effective refractoy preriods of right (13Cases) and left (4Cases) bundle branches. The effective refractory periods of bundle branch block measured by S1-S2 and P-S2 were quite similar, suggesting both of the programmed methods were reliable.
