Overview
- Intrinsic paroxysmal AV block is characterized by atrial premature beats/ventricular premature beats prior to and during the period of asystole.
- Extrinsic vagal paroxysmal AV block is characterized by sinus rate slowing, increasing PP interval/PR interval prior to the period or asystole.
- Extrinsic idiopathic paroxysmal AV block is characterized by narrowing of QRS complexes and sinus rate increase prior to the period of asystole.
ECG examples
Classic ECG Findings seen in the different types of paroxysmal AV Block are as follows :
