Abstract:
High-density electroanatomical mapping during orthodromic tachycardia with alternating short- and long-VA conduction patterns demonstrated an identical earliest atrial breakthrough. Although this supports a common atrial insertion, it cannot distinguish functional longitudinal dissociation within a single accessory pathway from closely adjacent ventricular pathway components converging into a common atrial insertion.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
