The Loss of p21-Activated Kinase (Pak1) Promotes Atrial Arrhythmic Activity The Role of Pak1 in Atrial Arrhythmia

Atrial fibrillation (AF) is initiated through arrhythmic atrial excitation from outside the sinus node or remodeling of atrial tissue that allows reentry of excitation. Angiotensin II (AngII) has been implicated in initiation and maintenance of AF through changes in Ca2+ handling and production of reactive oxygen species (ROS).
