New information on cardiac rhythm disorders has accumulated at a prodigious rate. This information has derived largely from two electrophysiologic techniques, often used together. One measures the impulse formation at the His bundle, which permits close examination of events occurring in and around the atrioventricular (AV) node. The other utilizes various forms of pacing, often in several locations within the heart. Together these techniques allow the cardiac physiologist to "map" a variety of conduction disturbances and tachyarrhythmias.
Although intracardiac recording techniques have proved a sophisticated research tool, they have created in their wake a series of questions. Are these techniques
