[Significance of atrial signal-averaged electrocardiogram analysis in diagnosis of paroxysmal atrial fibrillation in patients with mitral valve prolapse syndrome].
The aim of this study was to assess the clinical usage of recording time-domain parameters of atrial signal-averaged electrocardiogram (ASAECG) in diagnosis of paroxysmal atrial fibrillation (PAF) of patients with mitral valve prolapse (MVP). 85 patients with MVP recognized by echocardiography were divided into two groups: group I (MVP-PAG/+/) 41 pts (15 male and 26 female) mean age 37.1 +/- 8.9 with previously electrocardiographically documented episode of PAF, group II (MVP-PAF/-/) 44 pts (20 male, 24 female) mean age 39.1 +/- 14.3 without PAF. The control group III consisted of 35 persons: 24 male and 11 female in mean age 37.7 +/- 6.2 without any cardiovascular diseases. All patients underwent additional investigations included: T3, T4, electrocardiography, exercise-test with moving "running track", 24-hours monitoring ECG with Holter's method and ASAECG recording. The following time-domain parameters of ASAECG were calculated: the root mean square voltage of the terminal 10, 20, 30 ms of the filtered P-wave (RMS 10, 20, 30) and total time duration of filtered P-wave (PWD). The adaptation of time-domain parameters of atrial signal-average in differential diagnostics of PAF during MVP has appeared as useless from clinical point of view.
