Arrhythmias and arrhythmology ECG Aberrant ventricular conduction (aberrancy, aberration) Aberrant conduction is not a mechanism of arrhythmia; it is a ventricular conduction disturbance . It is…

…AVRT (Pre excitation, Wolff Parkinson White syndrome) and ectopic atrial tachycardia have traditionally been referred to as paroxysmal supraventricular tachycardias , because these tachyarrhythmias originate in…

…depolarization (i.e they display automaticity) and can therefore act as latent pacemakers (which become active when atrial impulses do not reach the atrioventricular node)…

…The impulse discharged from an ectopic focus in the ventricles will spread abnormally (because the impulse did not enter the ventricles through the bundle of…

…sinoatrial pause (sinus pause/arrest): ECG characteristics & clinical implications A sinoatrial arrest occurs when the sinoatrial node does not discharge an impulse for ≥2 seconds…
