Physical Adjustment

Effective cardiac resynchronization therapy (CRT) requires an accurate atrio-biventricular pacing system. The innovative Quartet lead is a quadripolar, over-the-wire left ventricular lead with four electrodes and has recently been designed to provide more options and greater control in pacing vector selection. A lead with multiple pacing electrodes is a potential alternative to physical adjustment of the lead and may help to overcome high thresholds and phrenic nerve stimulation (PNS).

Resynchronisation Therapy

Troubleshooting of left ventricular (LV) lead fractures in cardiac resynchronisation therapy patients is important, especially for those with limited and problematic transvenous LV lead placement. In this case, surgical epicardial LV lead implantation was employed.
