Sudden cardiac death is a major cause of mortality in patients with chronic bifascicular block and is strongly associated with underlying coronary disease and ventricular dysrhythmias.
Prospective follow-up studies of 277 patients with chronic bifascicular block showed that 30 patients developed sudden cardiac death (SCD). Cumulative one-, two-, and three-year SCD mortality was computed. The patients that developed SCD were compared with the remaining patients (209 alive and 38 dead). The groups were similar in regard to age, sex, AH, and HV intervals. The following were more frequent in the SCD group (PArch Intern Med137:1005-1010, 1977)
