A 76 year-old patient after the implantable cardioverter-defibrillator (ICD) implantation as a primary prevention of sudden cardiac death was admitted to the hospital because of the electrical storm which presented in ECG as a variety ventricular arrhythmia. Because of patients' resistance for pharmacological treatment and antiarrhythmic therapies delivered from ICD, we performed an ablation and implemented the resynchronisation therapy of the heart.
