Research output: Contribution to journalArticlepeer-review


A case is presented in which left anterior hemiblock (LAH) appeared transiently after the pause terminating atrial pacing, after atrial premature beats and during the slowing of sinus rhythm induced by carotid sinus massage. The transient LAH is attributed to phase-4 block, and is reported in order to add weight to the hypothesis that phase-4 block is a significant factor in the genesis of discrete conduction blocks in the human heart.
