ABSTRACT
OBJECTIVE@#To evaluate the electrocardiographic characterizations of atrial contractions(AC) triggering paroxysmal atrial fibrillation(AF), and to explore the effects of AF prevention pacing on their electrocardiographic characterizations.@*METHODS@#Twenty-four patients with the implantation of AF therapy pacemaker(Vitatron 900E) were analyzed by AC triggering paroxysmal AF with Holter monitoring in the study. AC compluing interval, compensatory pause and frequency 2 minutes before the AF or during the AC were compared between the induced paroxysmal AF group and noinduced paroxysmal AF group, and the preventive effect of AF on the post-PAC response program was investigated.@*RESULTS@#There was significant difference in the AC compluing interval [(352.3 +/-30.4) vs (421.8 42.5)ms], compensatory pause [(963 +/-109) vs (733 +/-124) ms], and frequency [(34.8 +/-18.9) vs (12.7 +/-8.7)/min] 2 minutes before the AF or during the AC in the induced paroxysmal AF group, compared with those in the noinduced paroxysmal AF group (all P<0.05). The AF of 7 patients were controlled by atrial overdrive pacing therapy, 17 patients by post-AC-response or/and post-exercise control therapy, 6 patients by the above therapy combining with cordarone (0.2g/d).@*CONCLUSION@#AC triggering paroxysmal AF is related to the compluing interval, compensatory pause and frequency 2 minutes before the paroxysmal AF or during the AC, AF prevention pacing may be helpful for the paroxysmal AF induced by AC.
