Impact of diabetes mellitus on pacing parameters and complications in patients with implantation of ;permanent artificial cardiac pacemaker / 心血管康复医学杂志

ABSTRACT

Objective:To observe the impact of diabetes mellitus (DM)on pacing parameters and postoperative com-plications in patients With implantation of permanent artificial cardiac pacemaker.Methods:A total of 80 patients With sick sinus syndrome,Who received implantation of permanent artificial cardiac pacemaker from Jun 2008 to Jun 2011,Were enrolled.According to complicated With DM or not,they Were divided into DM group (n=40)and non-DM control group (n=40).Pacing parameters and postoperative complications Were compared betWeen tWo groups.Results:There Were no significant difference in atrial and ventricular pacing threshold,sensing and of pace-maker impedance in baseline betWeen tWo groups (P>0.05).All parameters of pacemaker increased in tWo groups after implantation 12 months;compared With non-DM control group,there Were significant increase in pacing threshold [atrial(0.59±0.23)V vs.(0.67±0.25)V,ventricular(0.47±0.28)V vs.(0.54±0.35)V],sens-ing [atrial(2.33±1.16)mV vs.(2.92±1.36)mV,ventricular(12.21±4.82)mV vs.(12.77±5.36)mV], impedance [atrial(537.12±115.32)Ωvs.(662.48±235.26)Ω,ventricular(602.48±222.46)Ωvs.(762.41± 235.38)Ω]of pacemaker in DM group,P<0.05 or <0.01;and incidence rate of postoperative complications (12.5%)in DM group Was significantly higher than that of non-DM control group (5%),P<0.05.Conclusion:Electrocardiographic reconstruction is more severe in SSS patients complicated DM,in these patients postoperative complication incidence significantly elevates.
