A method for signal enhancement of electrograms of the specialized atrioventricular conduction system is presented. This method allows a single electrogram to replace the tracings of bipolar electrograms previously required to ensure recognition of the specialezed conduction system and yet maintains the safety afforded by use of three pairs of recording electrodes. In addition, this new signal is enhanced in magnitude and is always unidirectional (positive). These features are desirable for automated signal recognition. This method therefore provides an important step toward future automation and signal recognition of specialized conduction system electrograms during open-heart surgery.
本文提出了一种用于增强特殊房室传导系统心电图信号的方法。该方法允许用单个心电图来替代先前为确保识别特殊传导系统而所需的双极心电图描记，同时仍保持使用三对记录电极所提供的安全性。此外，这种新信号在幅度上得到增强，并且始终是单向的（正向）。这些特性对于自动信号识别是理想的。因此，该方法为心脏直视手术期间特殊传导系统心电图的未来自动化和信号识别迈出了重要一步。
