Abstract:
OBJECTIVETo compare the safety and efficiency of pacing at right ventricular outflow versus right ventricular apex.
METHODPatients were divided into two groups: pacing at ventricular cardiac apex (common pacing group, n = 22) and pacing at right ventricular outflow tract (uncommon pacing group, n = 18).
RESULTSImpedance and amplitude of R-wave were similar during implantation between the two groups (all P > 0.05). The pacing threshold and electric current were significant higher in uncommon group than those in common pacing group (all P < 0.05), however, these differences disappeared at 1 month post pacemaker implantation (all P > 0.05). The mean QRS duration tended to be shorter in uncommon pacing group compared to that in common pacing group (P > 0.05). There was no pacemaker associated adverse effect in both groups.
CONCLUSIONThe safety and efficiency of pacing at right ventricular outflow was similar as those of pacing at right ventricular apex.
