ECG rhythms

I. Supraventricular

• Normal sinus
• Sinus dysrhythmia
• Sinus bradycardia (<60)
• Sinus tachycardia (100-160)
• Premature atrial contractions
• Wandering atrial pacemaker
• Multifocal atrial tachycardia (100-180)
• Atrial flutter (250-350)
• Atrial fibrillation
• Paroxysmal supraventricular tachycardia

II. Junctional

• Narrow complex, rate 40-60
• DDx: CHF, myocarditis, hyperkalemia, Digoxen Toxicity

III. Ventricular

• Accelerated Idioventricular Rhythms (AIVR)
• Premature ventricular contraction
• Torsades de pointes
