Atrioventricular block (first of two parts).
The development of His-bundle (H) electrocardiography and the concept of hemiblocks have prompted a re-examination of conventional thinking about the indications for treatment of atrioventricular (AV) block.

The problem for this review is what these recent developments have contributed to deciding when and if a pacemaker should be installed.
