Long-Term Technical Performance of the Osypka QT-5 Ventricular Pacemaker Lead.

Background: Lead-associated complications and technical issues in patients with cardiac implantable electronic devices are common but underreported in the literature.

Methods: All patients undergoing implantation of the Osypka QT-5 ventricular lead at the University Clinic St. Pölten between 1 January 2006 and 31 December 2012 were retrospectively analyzed ( = 211).

Long-term performance of an atrial lead capable of accelerometer based detection of cardiac contractility in patients receiving cardiac resynchronisation therapy.

Objectives: To evaluate the long-term performance of the SonRtip atrial lead.

Background: To optimize atrioventricular and interventricular timing and thereby potentially improving cardiac resynchronization therapy (CRT) responder rates, a lead integrated technology and a cardioverter/defibrillator-based algorithm measuring peak endocardial acceleration have been introduced. Long-term performance of the atrial lead (SonRtip PS55D, Sorin/MicroPort CRM, Italy) embedded with such a sensor has not been reported so far.
