Induction and termination of triggered activity by pacing in isolated canine Purkinje fibers.

Abstract

The clinical importance of delayed afterdepolarizations and resultant triggered activity as a cause of cardiac arrhythmias is uncertain. We studied the response of ouabain-induced delayed afterdepolarizations and triggered activity to a pacing protocol similar to those used clinically in an effort to quantify the types of responses to pacing that occur as a… (More)
