Abstract:
Objective To apply 12-leads HOLTER monitoring and analysis to observe paroxysmal atrial fibrillation (PAF) and its related atrial arrhythmias so as to explore the triggering factors of PAF. Methods 47 patients with PAF, including 20 male patients and 27 female patients, were given 12-HOLTER monitoring and analysis. Their average age was 64.89 ±12.70 years-old.PAF patients were subdivided into 2 subgroups: the triggered PAF subgroup and the untriggered PAF subgroup. Patients with atrial premature beats but without PAF were selected into the control group. The PAF and its related atrial arrhythmias were detected and analyzed by 12-HOLTER.Results (1) 9 events of PAF were found in 47 patients by 12-HOLTER monitoring and analysis, among them 72 events of PAF were triggered by atrial premature (AP) (91.1%, 72/79), 6 events of PAF occurred automatically and suddenly (7.6%, 6/79);and only 1 events of PAF was triggered by atrial flutter (1.3%,1/79) . (2) The coupling interval of AP in the triggered PAF subgroup was significantly shorter than that of the untriggered PAF subgroup and control group (490 ±90ms vs. 590 ±140 ms and 630 ±90ms, <0.05);The index of AP was smaller significantly in the PAF group than that of the untriggered PAF subgroup and controll group (0.52±0.12 vs. 0.62±0.09 and 0.71±0.06, <0.05);TheP' on Tof AP was significantly higher in the PAF group than that of the untriggered PAF subgroup and control group (84.72%vs. 26.73%and 2.78%, <0.017);The interval before the AP in PAF group was prolonged more significantly than that of controlled group (990±280 ms vs. 940±210 ms, <0.05) . (3) During 2 min~30 s before the PAF occurrence control as total times,the AP appeared more frequently (from 0.43 beats/min to 3.5~6.00 beats/min, <0.017) . (4) Most of the AP which triggered PAF was originated from the upper part of the left atrium (61/72,84.7%) .Conclusions Most events of PAF are triggered by AP, the AP which can trigger PAF may be of some of the features such as a shorter coupling interval,a smaller AP index,P' on Tand a longer interval before the AP,PAF more occurrence while the AP may take place more frequently.Most of the AP which triggered PAF are originated from the upper part of left atrium.
