Abstract:
Objective To investigate the methodology and feasibility of bedside temporary cardiac pacing with balloon-tipped floating catheter by femoral vein approach.Methods 86 patients in this study were treated with bedside temporary cardiac pacing by femoral vein for arrhythmias.A balloon-tipped floating catheter was inserted through the femoral vein in right ventricle,guided by the length of catheter in body and the QRS morphology of pacing electrocardiogram(ECG).After that,the pacing site was identified by X-ray fluoroscopy.Then,the feasibility and successful rate of this bedside temporary cardiac pacing,and the causes for failure were analyzed.Results Guided by the length of catheter and the QRS morphology of pacing ECG,the succesful rate of balloon-tipped floating catheter putted into right ventricle was 98.8%.The most successful pacing sites were located at the right ventricular apex(RVA) and right ventricular out-flow tract(RVOT).The lengths of catheter from the puncture sites to RVA and RVOT were (57.2?3.2)cm and (54.3?3.1)cm,respectively.Incidence of undersensing in RVOT pacing group was significantly higher than that in RVA pacing group(P
