[Recording the bundle of His potential using an esophageal electrode].
A noninvasive method for recording His bundle potential is reported that includes amplification of ECG in bipolar esophagosternal leads. A total of 106 patients were examined, with the His potential recorded in 78 (73.6%) of those. The method was validated by simultaneously recorded intracardiac electrograms in 6 patients and by atrial pacing in 3 patients. The advantages and limitations of this method are discussed.
