Description : Progressive familial heart block type II (PFHB2) is an autosomal dominant disorder,
similar to type I progressive familial heart block (PFHB1; see 113900). The pattern
of PFHB2, however, tends to develop along the lines of a sinus bradycardia with a
left posterior hemiblock, presenting clinically as syncopal episodes, Stokes-Adams
seizures, or sudden death when complete heart block supervenes (Brink and Torrington,
1977).;
