Abstract:
His bundle recordings enable us to diagnose conduction disturbances not discernable in the standard leads, and to localize conduction block in the subdivisions of the conduction system. Cases of intra-His bundle block were first reported in 1970 by Narula and Samet. Thereafter many additional reports and studies were made. We report a case of 3degrees A-V block due to conduction block at the His bundle level. A 71-year-old woman was admitted because of dizziness. Surface ECG showed 3degrees A-V block. His bundle electrogram revealed typical split His potential. A-H intervals were 80 msec and H'-V intervals 50~70 msec. And there found no relation between AH and H'A. Atrial pacing resulted only prolongation of A-H to 90 msec but dissociation between h and H' was consistent. We implanted a permanent endocardial pacemaker in her chest.
