Key result
The presence of a supernormal period in the excitability of conduction tissues can explain cases of interference dissociation and paroxysmal heart block.

May explain rare paroxysmal blocks via supernormal excitability; hypothesis-generating without practice implications.
Case Report
The supernormal period of excitability in conduction tissues can play a role in maintaining normal sinus rhythm in rare cases of paroxysmal heart block.
Howard B. Burchell (1942) conducted a case report in Interference dissociation and paroxysmal heart block. Supernormal period in excitability of conduction tissues was evaluated. The presence of a supernormal period in the excitability of conduction tissues can explain cases of interference dissociation and paroxysmal heart block.
