Pacing the left ventricle (LV) from multiple sites simultaneously may result in a better response to cardiac resynchronization therapy (CRT). We sought to assess whether multisite pacing using a quadripolar LV lead improves acute hemodynamic response (AHR) to CRT. We paced four ventricular sites simultaneously using two vectors of a Quartet lead, a right ventricular apical lead, and an additional LV lead temporarily placed in an anterior branch of the coronary sinus. Multisite pacing using the Quartet lead alone did not improve the AHR but "quad-site" pacing using an additional temporary LV lead did increase dP/dt(max).
同时从多个部位对左心室（LV）进行起搏可能会使心脏再同步治疗（CRT）产生更好的反应。我们试图评估使用四极左心室导线进行多部位起搏是否能改善CRT的急性血流动力学反应（AHR）。我们使用Quartet导线的两个向量、一个右心室心尖导线以及一根临时置于冠状窦前支的额外左心室导线同时对四个心室部位进行起搏。单独使用Quartet导线进行多部位起搏并未改善AHR，但使用额外的临时左心室导线进行“四部位”起搏确实增加了最大dp/dt。
