[Passive-fixation ventricular lead of DDD pacing system implantation through left superior vena cava].

Passive-fixation of ventricular lead was implanted through left superior vena cava (LSVC) and DDD pacing system replaced AAI in a young patient with II degree A-V block. Good mechanical stability and proper bioelectrical parameters obtained in short-lasting, uncomplicated procedure does not stay in line with world-wide approach. It is preferential for active fixation of leads in the right ventricle through the LSVC.
