Özet
The acute or chronic effect of VVI pacing on P wave duration in the same patient with dual chamber pacemaker has not been studied before. Hence, with the purpose of determining whether VVI pacing increases dispersion of atrial refractoriness. we undertook a comparative study with the aid of a simple noninvasive approach. namely P wave dispersion (PWD) determined from surface electrocardiogram in the same patients who were implanted with dual chamber pacemakers. Pmax duration calculated in VVI paced mode was significantly higher than in VDD paced mode (121+/-21 vs. 111+/-17 ins, P=0.021). PWD (33+/-15 vs. 40 23 tris, P=0.062) did not demonstrate any significant difference between VDD and VVI paced modes, respectively. In conclusion. the findings of our study suggest that short-term VVI pacing itself does not have any direct effect on PWD in patients with dual chamber pacemakers. Different pacing modes in the long term might be responsible for altering PWD and the occurrence of atrial fibrillation while affecting the autonomic nervous system. (C) 2002 Elsevier Science B.V.
