چکیده
Figure 1 Changes in the 12-lead electrocardiograms (ECGs) during biventricular pacing with different left ventricular (LV) pacing configurations. A: Extended bipolar pacing between LV1 and right ventricular coil. B: Extended bipolar pacing between LV4 and right ventricular coil. C: LV bipolar pacing between LV1 (anode) and LV4 (cathode) with an output of 4.0 V/0.4 ms. The similar morphology to ECG A indicates anodal capture. D:LV bipolar pacing between LV1 (anode) and LV4 (cathode) with an output of the anodal capture threshold of 3.5 V/0.4 ms. An alternative appearance of ECGs B and C is shown. The morphology identical to ECG B (asterisks) indicates a loss of anodal capture.

Quadripolar Leads in Cardiac€Resynchronization Therapy
Ma Despite the benefit of cardiac resynchronization therapy (CRT) in patients with heart failure and conduction delay, a considerable number of patients do not respond substantially. Left ventricular lead position is an important factor in response, restricted by the patient’s specific anatomy and local pathophysiology. Quadripolar leads could enhance response to CRT, offering 4 pacing location...
متن کاملUse of a quadripolar left ventricular lead to achieve successful implantation in patients with previous failed attempts at cardiac resynchronization therapy
AIMS Problems with implanting a left ventricular (LV) lead during cardiac resynchronization therapy (CRT) procedures are not uncommon and may occur for a variety of reasons including phrenic nerve stimulation (PNS) and high capture thresholds. We aimed to perform successful CRT in patients with previous LV lead problems using the multiple pacing configurations available with the St Jude Quartet...
متن کاملQuadripolar Left Ventricular Lead in a Patient with CRT-D Does Not Overcome Phrenic Nerve Stimulation
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 adjustm...
متن کاملCardiac Resynchronization Therapy Delivered Via a Multipolar Left Ventricular Lead is Associated with Reduced Mortality and Elimination of Phrenic Nerve Stimulation: Long‐Term Follow‐Up from a Multicenter Registry
INTRODUCTION Cardiac resynchronization therapy (CRT) using quadripolar left ventricular (LV) leads provides more pacing vectors compared to bipolar leads. This may avoid phrenic nerve stimulation (PNS) and allow optimal lead placement to maximize biventricular pacing. However, a long-term improvement in patient outcome has yet to be demonstrated. METHODS A total of 721 consecutive patients wi...
متن کاملAnodal Stimulation: An Underrecognized Cause of Nonresponders to Cardiac Resynchronization Therapy
OBJECTIVE The purpose of this study was to determine if anodal stimulation accounts for failure to benefit from cardiac resynchronization therapy (CRT) in some patients. BACKGROUND Approximately 30-40% of patients with moderate to severe heart failure do not have symptomatic nor echocardiographic improvement in cardiac function following CRT. Modern CRT devices allow the option of programming...
