Classification Atrial Premature Atrial Contractions (PACs) Wandering Atrial Pacemaker Multifocal atrial tachycardia Atrial flutter Atrial fibrillation (Afib) Junctional arrhythmias Supraventricular tachycardia (SVT) AV nodal reentrant tachycardia is the most common cause of Paroxysmal Supra-ventricular Tachycardia (PSVT) Junctional rhythm Junctional tachycardia Premature junctional contraction Ventricular Premature Ventricular Contractions (PVC) sometimes called Ventricular Extra Beats (VEBs) Premature Ventricular beats occurring after every normal beat are termed "ventricular bigeminy" PVCs that occur at intervals of 2 normal beats to 1 PVC are termed "PVCs in trigeminy" Three premature ventricular grouped together is termed a "run of PVCs"; runs lasting longer than three beats are generally referred to as ventricular tachycardia Accelerated idioventricular rhythm Monomorphic Ventricular tachycardia Polymorphic ventricular tachycardia Ventricular fibrillation Heart blocks These are also known as AV blocks, because the vast majority of them arise from pathology at the atrioventricular node. They are the most common causes of bradycardia: First degree heart block, which manifests as PR prolongation Second degree heart block
Type 2 Second degree heart block, also known as Mobitz II Here are further guidelines. |
