            • Supraventricular tachycardia (SVT)
              • Any tachycardia with its origin above ventricles
              • Rates typically > 200
              • May have 1:1 atrioventricular (AV) conduction or variable degree of heart block (e.g., 2:1)

                • Automatic rhythms
                  • Sinus tachycardia

                • Reentrant rhythms
                  • AV reentry
                  • Atrial flutter
            • Ventricular tachycardia
              • Ventricular rate exceeds atrial rate
