Shape of complex | Diagnosis |
---|---|
Irregular narrow complex | Atrial fibrillation Atrial flutter (sawtooth pattern) Multifocal atrial tachycardia (distinct P waves, but with different morphologies) |
Regular narrow complex | Sinus tachycardia Atrial flutter with constant AV block AVNRT Accessory pathway re-entrant tachycardia |
Irregular broad complex | Atrial fibrillation + LBBB/RBBB Atrial fibrillation + other aberrant conduction |
Regular broad complex | Sinus tachycardia + LBBB/RBBB Atrial flutter with constant AV block + LBBB/RBBB Ventricular tachycardia |
AV: atrioventricular; AVNRT: atrioventricular nodal re-entrant tachycardia; LBBB: left bundle branch block; RBBB: right bundle branch block.
