Abstract: Objective To investigate the safety and efficacy of electrocautery in hemorrhagic tendency patients(being treated with anti-coagulant and anti-platelet) during permanent pacemaker implantation.Methods We Compared the hemostasis effectiveness,and complications during and after operation within four groupsgroup A(hemorrhagic tendency patients with electocautery,n=47),group B(hemorrhagic tendency patients without eclectrocautery,n=42),group C(non-hemorrhagic tendency patients with eclectrocautery,n=95) and group B(non-hemorrhagic tendency patients without eclectrocautery,n=91).Results Regardless patients with hemorrhagic tendency or without hemorrhagictendency the incidence of hemorrhage and hematoma was lower in the electrocautery groups.Especially,the electrocautery therapy proved more benefit in the hemorrhagic tendency patients(P=0.04).There were no complications of myocardial perforation,hemorrhoea,electrode dislodge and pacemaker system failure.There were no pocket erosion and the pacing parameters were coincident with program parameters during 1 year follow-up.Conclusion The electrocautery is safe and effective in permanent pacemaker implantation.
