His bundle recording is a simple, low-morbidity technique that can be reliably performed in most cardiac laboratories to better understand cardiac conduction.
, Scherlag and coworkers reported the recording of bundle of His electro- grams in man.1 The technique consists of passing an electrode catheter into the right heart and positioning the electrodes in the area of the tricuspid valve. With proper catheter positioning, amplffication and fre- quency filtering, the His bundle (H) potential can reliably be recorded as a bi-or triphasic deflection between the atrial and ventricular electrograms. The procedure is simple and has a low morbidity. With a little experience, recording of His bundle electrograms could be accomplished in most cardiac laboratories. Careful attention must be given to elimination of electrical hazards before attempting this procedure.
