During routine cardiac resynchronization pacemaker or implantable defibrillator (ICD) implantation (including de-novo and upgrade from standard device, additional pacing within 3 different coronary veins will be performed in combination with a previously implanted right ventricular pacing or ICD lead. The resulting electrocardiogram signal will be analyzed afterwards. A time-frequency analysis (TFA) of several ECG leads at each paced site will be performed and compared. The results of the TFA analysis will not be used to select pacing lead location in this study. The patient will then receive the left ventricular pacing lead in the standard manner.
