“…The delays in inter-atrial conduction time and intra-atrial conduction time and, prolonged P dis have been shown to be related to AF recurrence [12,13]. Ermis et al [14] reported increased risk of persitent AF development in pre-hypertensive patients who had prolonged P-wave duration.…”

“…Stepwise logistic regression analysis was performed to identify the independent predictors of AF recurrence. The independent variables include: clinical and electrocardiographic features that have been identified as predictors of AF (age, LA diameter, LVEF and PWD) (6)(7)(8)(9)(10)(11). Receiver operating characteristic (ROC) curve analysis was used to identify optimal cut-off values of PWD level to identify maximum sensitivity and specificity for detection of recurrent AFs.…”

ÖZETAmaç: P dalga dispersiyonu (PWD) atriyal iletimdeki farklılığı gösteren elektrokardiyografik bir ölçümdür. Bu çalışmanın amacı, eksternal kardiyoversiyon sonrası sinüs ritminde olan hastalarda PWD'nin atriyal fibrilasyon (AF) rekürrenslerini öngörmedeki tanısal değerini göstermektir. Yöntemler: Bu prospektif gözlemsel çalışmaya, başarılı eksternal kardiyoversiyonla sinüs ritmi sağlanmış, kapak hastalığı dışı persistan AF'si olan 26 hasta dâhil edildi (13 erkek, yaş ortalaması 58.1±11 yıl). Eksternal kardiyoversiyondan hemen sonra, P dalga süresini ölçmek için tüm hastaların 12 derivasyonlu yüzeysel elektrokardiyografileri çekildi. Sinüs ritmi sağlandıktan sonraki 12 aylık takip süresinde tüm hastaların tekrar eden AF'leri değerlendirildi. Hastalar AF rekürrens gelişimine göre 2 gruba ayrıldı (AF rekürrens grubu (n=19) ve sinüs ritim grubu (n=7)) ve bu gruplar, AF rekür-renslerini etkileyebilecek değişkenler açısından karşılaştırıldı. Atriyal fibrilasyon rekürrensinin bağımsız öngördürücülerinin belirlenmesinde basamaklı lojistik regresyon analizi ve bağımsız öngördürücülerin kestirim değerinin belirlenmesinde ROC eğrisi analizi kullanıldı. Bulgular: Her iki grubun demografik, klinik ve ekokardiyografik özellikleri benzerdi. Atriyal fibrilasyonu tekrarlayan hastaların PWD değerleri sinüs ritmi devam eden hastalara göre anlamlı olarak daha yüksekti (sırasıyla 80±21 msn ve 53±11 msn, p=0.001). P dalga dispersiyonundaki artış ile AF'nin tekrarlama riski arasında pozitif korelasyon izlendi (r=0.643; p<0.001).Lojistik regresyon analizinde PWD AF rekürrensinin bağımsız ABSTRACT Objective: P-wave dispersion (PWD) is an electrocardiographic measurement, which reflects a disparity in an atrial conduction. In this study, we aim to demonstrate the diagnostic accuracy of PWD in predicting recurrence of atrial fibrillation (AF) in patients with sinus rhythm restoration after external cardioversion. Methods: This prospective, observational study consists of 26 patients, who underwent external cardioversion for non-valvular persistent AF and successfully cardioverted to sinus rhythm (13 men, mean age 58.1±11 years). Twelve-lead surface electrocardiogram of each patient was recorded immediately after the external cardioversion process to measure the P-wave duration. Recurrent AF was assessed for each patient during the 12-month follow-up after restoring the sinus rhythm. Patients were divided into the 2 groups with respect to the AF recurrence (recurrent AF group, (n=19), and sinus rhythm group, (n=7)) and variables that can affect AF development were compared between the two groups.Stepwise logistic regression analysis was used to identify the independent predictors of AF recurrence and ROC curve analysis was performed to determine the cut-off value of independent factors. Results: The two groups have similar demographic, clinical and echocardiographic features. Patients with recurrent AF had significantly higher PWD than those who continued to have a sinus rhythm (80±21 msec vs 53±11 msec, p=0.001, respectively). There is ...

SummaryThe objective of the study was to determine the effects of nasal continuous positive airway pressure (nCPAP) therapy on left ventricular (LV) function and electrocardiographic parameters in newly diagnosed moderate/severe obstructive sleep apnea (OSA) patients without cardiovascular comorbidities and medical treatments. We examined 44 patients who underwent overnight polysomnography together with 24-hour Holter electrocardiography, cardiopulmonary exercise testing including heart rate recovery at 1 minute (HRR-1), echocardiography, surface electrocardiography, and those who were diagnosed with moderate/severe OSA apnea-hypopnea index ≥ 15. After 3 months of nCPAP treatment, the above-mentioned examinations were repeated. Forty-four patients completed the treatment period. Twelve weeks on effective nCPAP induced a significant increase in the mitral E/A ratio (P = 0.001), as well as reductions in isovolumic relaxation time (P = 0.001) and mitral deceleration time (DT) (P = 0.002). There were no significant differences in LV ejection fraction, LV mass index, and pulsed wave Doppler parameters. Mean heart rate was 79.2 ± 12.5 pulses/minute, maximum P-wave duration 117.5 ± 8.6 msec, P-wave dispersion (PWd) 54.6 ± 10.2 msec, corrected QT interval (QTc) 436.5 ± 40.5 msec, and QT dispersion (QTd) 46.3 ± 7.1 msec, which significantly decreased to 70.4 ± 9.6 pulses/minute (P < 0.001), 111.5 ± 8.7 msec (P < 0.001), 51.6 ± 8.9 msec (P < 0.001), 418.4 ± 31.2 msec (P < 0.001), and 33.8 ± 3.4 msec (P < 0.001), respectively. Exercise capacity at baseline determined as 10.5 ± 2.2 metabolic equivalents (METS) and HRR-1 (20.6 ± 11.7 bpm) significantly increased (12.1 ±1.5 METS and 27.4 ± 8.6 bpm). There was no significant difference in aortic root parameters. Three-month nCPAP therapy significantly increased LV shortening fraction, with no effect on systolic function or aortic root diameters and a positive effect on heart rate, PWd, HRR-1, QTc and QTd time following nCPAP therapy.
