AV Block: 2nd degree, Mobitz I (Wenckebach Phenomenon)
A review of the basic ECG features, causes and pathophysiology of Mobitz I AV Block (Wenckebach Phenomenon) with some example ECGs.
Focal Atrial Tachycardia (FAT)
Atrial tachycardia is a form of supraventricular tachycardia, originating within the atria but outside of the sinus node
Premature Atrial Complex (PAC)
Review of the atrial ectopics and premature atrial contractions (PACs) with ectopic pacemaking tissue within the atria
Arrhythmogenic Right Ventricular Dysplasia (ARVD)
A review of the ECG features of arrhythmogenic right ventricular cardiomyopathy (ARVC) AKA: arrhythmogenic right ventricular dysplasia (ARVD)
Anterior Myocardial Infarction
Anterior STEMI usually results from occlusion of the left anterior descending (LAD) artery and carries the poorest prognosis of all infarct territories
Accelerated Junctional Rhythm (AJR)
AJR occurs when the rate of an AV junctional pacemaker exceeds that of the sinus node. Seen in digoxin toxicity and myocarditis
Accelerated Idioventricular Rhythm (AIVR)
AIVR -- benign rhythm that occurs when rate of an ectopic ventricular pacemaker exceeds sinus node. Often seen in reperfusion phase following anterior STEMI
