Bradycardia
DESCRIPTION Just like sinus rhythm, but slower; it is defined as sinus rhythm (every QRS preceded by a proper P wave) with a rate under 60. HABITAT Boring lectures, a…
Atrial Pacemaker
DESCRIPTION A sort of poetic description, suggestive of a thoughtful atrial pacemaker, pipe in hand, strolling around the campus, perhaps bumping into an occasional tree. Actually, the label suggests that…
Preexcitation
DESCRIPTION Technically this isn’t an arrhythmia (actually, even non-technically it isn’t!) but this condition provides the substrate for some crazy arrhythmias, so I thought I’d include it. Your attendings always…

DESCRIPTION This, technically, isn’t an arrhythmia at all, but needs to be included simply because it’s very important to be able to call something “normal” if it really is! The…
Tachycardia
DESCRIPTION The same as sinus rhythm, only faster: by definition, sinus rhythm with a rate over 100. Each QRS is preceded by a proper P wave. If you are seeing…
