Abstract: Objective To explore the safety,feasibility and efficacy of emergency bedside temporary pacing wire electrodes implanted via femoral veins.Methods Forty patients with severe bradycardia(26 men,14 women) aged(67±18.7) years(range,36-79 years) were selected from March 2005 to February 2010 in departments of cardiology and emergency,and emergency bedside temporary pacing wires were introduced via femoral veins in these patients under non-perspective conditions.After pacing,routine chest X-ray was performed to observe the location of pacemaker electrode tip,which was determined by perspective view in higher level hospitals.Results Temporary pacing was successful in all patients,with a success rate of 100%.The time spent in placing temporary pacing wires averaged(11.5±4.3) minutes(range,5-18 minutes).None of these patients had venous thrombosis,myocardial perforation,puncture site infection or other local complications.Conclusion Under non-perspective conditions,temporary pacing wire electrodes implanted via femoral veins is safe,convenient and feasible with a high success rate for emergency bedside temporary pacing,which can avoid life-threatening because of transportation,protect the puncture site and the approach to permanent pacemaker implantation and create the advantage conditions to save lives of transfer patients.
