[Recording the bundle of His potential from the chest surface].
An attempt was made to record the bundle of His potential from the chest surface in 38 persons by means of definite filtration, intensification, and averaging of the ECG. Three electrode leads were used for each person examined: transthoracic, horizontal, and on the longitudinal heart axis. In 34 persons (89%) the potential was recorded in the P--Q interval, its width and distance from the QRS complex corresponded to the parameters of the bundle of His potential. The potential was recorded most frequently in the transthoracic lead (50%).
