Abstract ObjectiveTo investigate the clinical significance of
MVP ECG risk score in patients with paroxysmal atrial fibrillation (PAF). MethodsSeventy patients with PAF(PAF group) and 83 subjects without atrial fibrillation (non-PAF group) were selected while 63 healthy subjects who had taken physical examination were enrolled as control group. The three groups of research subjects all underwent routine 12-lead synchronous ECG exami-nation. P-wave morphology and duration in inferior wall leads, and P-wave voltage in lead Ⅰ were measured and analyzed. MVP scores were compared between the PAF group and non-PAF group. ROC curve analysis was used to determine the critical value of MVP score in predicting PAF. Results(ⅰ) Compared with the non-PAF group, the age and the left atrium diameter (LAD) values of patients in the PAF group significantly increased \[age: (53.40±11.57) years old vs. (62.70±10.70) years old, P<0.01; LAD: (36.90±4.50) mm vs. (41.80±5.73) mm, P<0.01\] while left ventricular ejection fraction values of the PAF group decreased significantly \[(65.20±5.40)% vs. (61.70±11.77)%, P<0.01\]. Other clinical indexes do not vary significantly between the PAF group and non-PAF group (P>0.05). (ⅱ) The MVP scores in the PAF group are significantly higher than those in the non-PAF group in the same age subgroup of ≤ and > 60 years old [≤60 years old: (2.40±1.07) scores vs. (1.80±0.58) scores, P<0.05; >60 years old: (2.30±0.82) scores vs. (1.70±0.56) scores, P<0.05]. (ⅲ) The area under curve of MVP scores for PAF prediction is 0.65 (P<0.05). When MVP score of 2.5 is taken as the critical value, its sensitivity and specificity in predicting PAF are separately 35.7% and 97.3%. ConclusionThe MVP score of patients with PAF is significantly increased, and the MVP score of 2.5 may be of certain value in predicting the onset of PAF.
