title: Indications for His bundle recordings.
abstract: While the extrapolation of data derived from His bundle studies performed over the past 10 years has lessened the need to apply the technique for diagnostic clinical purposes, His bundle recordings remain a useful clinical research tool for better understanding of cardiac electrophysiology. Some of the areas of continued research to which the technique will most certainly be applied are: (1) study of reentrant phenomena involving the atrial, junctional, and ventricular regions of the heart, (2) investigation of the mechanisms of action of new and old drugs on the heart, (3) evaluation of effectiveness of drug treatment in resistant cardiac arrhythmias, and (4) understanding of complex arrhythmias.
