Tachycardia induced cardiomyopathy

Tachycardia induced cardiomyopathy (TIC) (or tachycardiomyopathy) is considered a reversible form of acquired cardiomyopathy where there is impaired left ventricular systolic dysfunction precipitated by a tachycardia or a tachyarrhythmia.

Typically there is an impairment left ventricular systolic function measured by an impairment left ventricular ejection fraction (LVEF) precipitated in a context of a tachycardia or tachyarrhythmia. The LVEF would return to normal limits in the absence of any other possible diagnosis once the tachycardia is corrected for the diagnosis to be made.

Usually there is marked improvement in systolic function after normalisation of heart rate.

It is thought to have been first described by G H Whipple in 1967.
