Tachycardia-induced cardiomyopathy (TIC) is characterized by reversible left ventricular (LV) dysfunction caused by long-standing tachycardia.

Advanced imaging and endomyocardial biopsy should be taken into consideration in the future as contributors in the diagnostic process. https://www.foldlyers.shop/product-category/tactile-switches/
