P波时限、P波离散度对特发性心房颤动的预测价值初探

Objective:To assess the sensitivity and the specifity of predicting idiopathic AF with P wave dura-tion and P wave dispersion. Methods: The maximum P wave duration and P wave dispersion in 36 patients with idio-pathic AF were measured and compared with those of sex-and age-matched healthy subjects. Results:The maxi-mum P wave duration and P wave dispersion were higher in patients with idiopathic Af than in control group. Themaximum P wave duration >110ms or P wave dispersion >40ms was used to differentiate patients from healthy

THE FEASIBILITY OF PREDICTING IDIOPATHIC ATRIAL FIBRILLATION ( AF) WITH P WAVE DURATION AND P WAVE DISPERSION

Objective:To assess the sensitivity and the specifity of predicting idiopathic AF with P wave duration and P wave dispersion. Methods:The maximum P wave duration and P wave dispersion in 36 patients with idiopathic AF were measured and compared with those of sex - and age - matched healthy subjects. Results:The maximum P wave duration and P wave dispersion were higher in patients with idiopathic Af than in control group. The maximum P wave duration > 110ms or P wave dispersion >40ms was used to differentiate patients from healthy subjects, the sensitivity and the specifity value were 88% vs 82% and 75% vs 86% respectively. When the above two parameters were integrated, the sensitivity was 76 % , the specifity 88 %. Conclusion: The maximum P.wave duration and P wave dispersion are simple and practical ECG indexes for idiopathic AF patients.
