Key result
Pacemaker insertion for trifascicular block reveals ~15% of patients eventually develop complete heart block.

Does programmed chest-wall stimulation safely evaluate the progression of A-V block in patients with trifascicular disease and a pacemaker?
Programmed chest-wall stimulation is a useful technique to evaluate underlying rhythm in pacemaker patients, revealing that complete A-V block can develop after a long paroxysmal phase in patients with trifascicular disease.
Marinato et al. (1982) conducted a cohort in Trifascicular block with syncope and/or dizzy attacks (n=26). Pacemaker insertion was evaluated on Development of complete heart block. Following pacemaker insertion for trifascicular block, 15% of patients developed complete heart block, indicating a long paroxysmal phase may precede chronic complete A-V block.
