导管法希氏束电图(简称HBE)在描记的同时,如有必要还可进行其他电生理检查,包括了解窦房结的空能,测定房室传导系统各部位的反拗期,以及通过心房起搏发现隐匿性房室传导阻滞和推测预激综合征中旁路的位置等,从而提供更多有价值的资料,有助于心脏传导系统疾病的及时诊断、正确处理和判断预后,故在心血管临床上有较广泛的应用。 Catheterization of Hischs beam electrogram (referred to as HBE) in the tracing at the same time, if necessary, but also for other electrophysiological examination, including the understanding of the energy of the sinoatrial node, atrioventricular conduction system to determine the various parts of the anti-staging, and through Atrial pacing found occult block atrioventricular block and predict the location of the pre-excitation syndrome in the bypass, etc., to provide more valuable information to help timely diagnosis of heart disease conduction system to correctly handle and determine the prognosis, Therefore, the clinical application of cardiovascular more widely.
