Objective The purpose of this study was to observe the effect of anodal capture at the ring electrode of the right ventricular ( RV) lead in cardiac resynchronization therapy. Methods Left and right ventricular capture threshold in the 16 consecutive patients who have been underwent CRT were measured. In these patients, left ventricular capture threshold in the mode of unipolar and LVtip-RVring were measured. Meanwhile, 12 lead ECG was simultaneously recorded. The pulse width of threshold test is fixed on 0.4 ms and the voltage scan from 7. 5 V to threshold of capture. We compared the morphology and duration of the QRS complex in several situation, then determined whether this phenomena was existed. QRS morphology varying the VV interval from 80,60,40to 20 and 4 ms in these patients whose anodal capture were recorded were investigated to study the effect of anodal capture to VV optimization. Results RV anodal capture during LV pacing was found in 4/16 patients. The threshold of anodal capture is (4.75±0.00) V, however, the threshold of LV is (1. 19±0. 01) V. The function of VVoptimization was lost in these patients who had such phenomena. Anodal RV capture threshold was affected by changes in pulse width duration, pacing pole and output voltage of LV. Conclusions There are anodal capture in some patients underwent CRT. This may affect the clinical response to alternative resynchronization methods using single LV stimulation or interventricular delay programming. So, we must pay more attention for this phenomena and deal with it in time.
