[Ventricular bigeminy as a cause of CRT inefficacy and inappropriate cardioverter-defibrillator intervention].
Double counting of ventricular beats is not only one of the cause of an inappropriate detection of ventricular arrhythmias but a reason of lost of resynchronisation therapy. Sensing disturbances often creates the need for reprogramming of the device or additional pharmacotherapy and procedures. We present a case of 76-year-old man with CRT-D and inappropriate detection and intervention due to ventricular bigeminy. Fortunately, change of device program, potassium and magnesium supplementation was successful, without necessity of RF ablation of the ventricular ectopic beats.
