Wearable cardioverter-defibrillator (WCD) is an excellent treatment option for patients with temporary increased arrhythmic risk. In presented case, 68-year-old patient was treated with WCD due to acute myocarditis. Telemonitoring revealed recurrent wide-QRS complex tachycardia which led to urgent hospitalization and clinical reevaluation. In electrophysiological study, orthodromic atrio-ventricular reentrant tachycardia with aberrancy

Although certain group of patients can benefit from cardiac resynchronization therapy, many patients do not fulfil criteria for such treatment. Cardiac contractility modulation (CCM) could be an option for them. CCM, by delivering of non-excitable impulses can improve cardiac contractility with concomitant HF symptoms reduction. In presented case, patient benefited from
