Overview
Based on the cause, paroxysmal AV block maybe classified into Intrinsic AV Block, Extrinsic Vagal AV block and Extrinsic Idiopathic AV Block.
Classification
- Paroxysmal AV Block may be classified according to the cause into three types :
- Intrinsic AV Block (I-AVB)
- Extrinsic Vagal AV Block (EV- AVB)
- Extrinsic Idiopathic AV Block (EI- AVB) "Syncope and paroxysmal atrioventricular block - Aste - 2017 - Journal of Arrhythmia - Wiley Online Library".
| Paroxysmal AV Block classification based on cause | |||||||||||||||||||||||||||||||||||
| Intrinsic AV Block (I-AVB): Due to innate structural/ conduction defect | Extrinsic Vagal AV Block (EV- AVB): Due to vagal surge/reflex | Extrinsic Idiopathic AV Block (EI- AVB) : Due to innately low adenosine plasma levels | |||||||||||||||||||||||||||||||||
| Tachycardia Dependent AV Block (TD- AVB) | Bradcardia/Pause Dependent AV Block (BD- AVB/PD-AVB) | ||||||||||||||||||||||||||||||||||
