A number of conditions may be associated with a persistent tachycardia sufficient to cause tachycardia-induced cardiomyopathy.


Endocrine disorders:

(1) thyrotoxicosis

(2) glucagonoma

(3) ? pheochromocytoma


Supraventricular tachyarrhythmia:

(1) atrial fibrillation

(2) atrial flutter

(3) atrial tachycardia

(4) AVRT (AV reciprocating tachycardia)

(5) AVNRT (AV nodal re-entrant tachycardia)


Permanent form of junctional tachyarrhythmia:

(1) persistent junctional reciprocating tachycardia (PJRT)

(2) atrial pacing at high rates


Ventricular tachyarrhythmia:

(1) premature ventricular complexes (PVCs)

(2) right ventricular outflow tract ventricular tachycardia

(3) idiopathic left ventricular tachycardia

(4) bundle-branch re-entry ventricular tachycardia

(5) myocarditis

(6) ventricular pacing at high rates
