AbstractPatients with atrial septal defect have an increased risk for atrial fibrillation. Increased P-wave dispersion predicts the development of atrial fibrillation. The aim of this study was to determine difference in P dispersion between transcatheter closure with Amplatzer septal occluder and surgical closure in childhood. A total of 68 children (the mean age was 7.2 plus or minus 3.3 years; the mean secundum atrial septal defects diameter was 17.3 plus or minus 5.4 millimetres) were evaluated in this study. Transcatheter closure was attempted in 41 children with secundum atrial septal defects, and the defect in 27 patients was closed by surgical techniques. P maximum, P minimum and P dispersion were measured by the 12-lead surface electrocardiography. P maximum, P minimum and P dispersion were found to be similar in patients with pre- and post-procedure (98.0 plus or minus 19.3 versus 95.1 plus or minus 23.0 milliseconds; 68.0 plus or minus 20.8 versus 67.6 plus or minus 24.3 milliseconds, 29.9 plus or minus 11.0 versus 27.1 plus or minus 12.1 milliseconds, respectively). There was no statistical significance in the comparison of P dispersion between the two groups. But in the surgical group, P-wave dispersion was decreased more significantly compared with baseline values (p-value equal to 0.03). In conclusion, there is no P dispersion between transcatheter closure with Amplatzer septal occluder and surgical closure of secundum atrial septal defect.

AbstractAtrial dysrhythmia is an important cause of mortality and morbidity in patients with atrial septal defect. Increased P wave duration can predict the risk of atrial dysrhythmia. The aim of this study is to evaluate the risk of atrial dysrhythmia by measuring P wave dispersion, and to observe the effect of surgical and transcatheter closure. Sixty-one patients and 30 controls were investigated. In patient group, before and after closure and in control group at the time of presentation, 12-lead electrocardiography records were evaluated. P wave duration and amplitude, P wave axis, PR interval, P wave dispersion, QRS axis, corrected QT interval, and QT dispersion were calculated. The measurements in patient and control groups, measurements before and after closure, and measurements of surgical and transcatheter group were compared. There were 27 patients in surgical group and 34 patients in transcatheter group. In patient group, signs of right heart volume overload were apparent but there was no significant difference in terms of P wave dispersion between two groups. We compared patient group in itself and found that while the use of medication, cardiothoracic index, ratio of right ventricular dilation, and paradoxical movement in interventricular septum were increased, mean age of closure was younger in surgical group. While P wave dispersion decreased in transcatheter group after closure, it increased in surgical group (p = 0.021). In conclusion, atrial septal defects may cause atrial repolarisation abnormalities and this effect persists even after surgical closure. Transcatheter closure in childhood may decrease dysrhythmia risk in long-term follow-up.

Introduction: P-wave dispersion (PWD) obtained from the standard 12-lead electrocardiography (ECG) is considered to reflect the homogeneity of the atrial electrical activity. The aim of this investigation was to evaluate the effect of percutaneous chronic total occlusion (CTO) revascularization on the parameters of P wave duration and PWD on ECG in cases before and after procedure at 12th months. Methods: We analyzed 90 consecutive CTO cases who were on sinus rhythm and underwent percutaneous coronary intervention (PCI). P-wave maximum (P-max) and P-wave minimum (P-min), P-wave time, and PWD were determined before and twelve months after the CTO intervention. The study population was categorized into two groups as successful and unsuccessful CTO PCI groups. Results: The CTO PCI was successful in 71% of cases (n=64) and it was unsuccessful in 29% of cases (n=26). Both groups, except for age and hypertension, were similar in terms of demographic and clinical aspects. CRP levels were significantly elevated in the unsuccessful CTO PCI group. Pre-PCI ECG parameters showed no significant difference. Irrespective of the target vessel revascularization, we observed that PWD and P-max values were significantly lower in the 12th months follow-up. In all Rentrop classes, PWD values were significantly decreased at 12th months follow-up in comparison to the pre-CTO PCI values. Conclusion: This study has determined that PWD and P-max, which are both risk factors for atrial arrhythmias, are significantly reduced within 12th months after successful CTO PCI regardless of the target vessel.

Backgrounds: The right insular cortical stroke is believed to have arrhythmogenic potential such as secondary atrial fibrillation (AF). The P wave-triggered signal-averaged electrocardiogram (SA-ECG) can reveal the P wave dispersion which is associated with the risk of AF in the future. However, there has been no relevant clinical study and we investigated the P wave dispersion after stroke involving right insula. Methods: We recruited acute stroke patients consecutively, who admitted from February 2012 to October 2013 and took routine work-up with SA-ECG. Patients who had AF on admission were excluded. SA-ECG was followed up two years after stroke onset. Significant P-wave dispersion was defined as ‘P-wave duration (PWD) >125ms for the predictor of future AF risk. We analyzed the difference of SA-ECG between the right insular cortex lesion and other stroke. Results: A total of 252 subjects were enrolled and 49 among them had right insular involvement. Follow up SA-ECG were available in 69 patients. In acute stroke period, the patients with right insular lesion had longer P wave duration than the other stroke patients (154.0+29.6 vs. 133.5+26.5 ms, p<0.001). In the patients with right insular involvement, prolonged P wave duration in acute period was shortened in follow up SA-ECG after two years (n=17, 164.5+35.2 vs. 131.7+22.3 ms, p=0.003). However, patients with other stroke lesion did not show such interval change. During observation period, AF occurred more frequently in the subjects with right insular lesion than other stroke patients (33% vs 17%, p=0.01). Conclusion: Our data suggest that the right insular lesion is associated with increased P wave dispersion transiently in acute stroke period and this might explain the development of secondary AF shortly after right insular cortex stroke.

Background/Aims: The P-wave parameters that are measured using a 12-lead electrocardiogram are commonly used as noninvasive tools for assessing left atrial enlargement. This study was designed to assess whether P-wave dispersion is associated with overall and cardiovascular mortality in hemodialysis patients. Methods: This study enrolled 209 hemodialysis patients. We measured the P-wave dispersion corrected by heart rate, that is, the corrected P-wave dispersion (PWdisperC), and assessed its correlation with overall and cardiovascular mortalities. Results: The mean PWdisperC of all the patients was 93.3 ± 21.1 ms. During the follow-up period (mean 5.4 years), 58 deaths and 37 cardiovascular deaths were recorded. The adjusted value of PWdisperC was also associated with overall (hazards ratio (HR) 1.018, 95% CI 1.004-1.033, p = 0.014) and cardiovascular (HR 1.032, 95% CI 1.012-1.053, p = 0.002) mortalities. Multivariate Cox regression analysis identified tertile 3 of PWdisperC (vs. tertile 1) to be associated with overall (HR 2.472, 95% CI 1.181-5.174, p = 0.016) and cardiovascular (HR 3.896, 95% CI 1.463-10.376, p = 0.007) mortalities, after adjustment for demographic, clinical and biochemical parameters. Adding PWdisperC to a model of clinical features could significantly improve the predictive value for overall (p = 0.044) and cardiovascular (p = 0.002) mortalities. Conclusions: We concluded that PWdisperC was positively associated with overall and cardiovascular mortalities in hemodialysis patients and could provide additional prognostic values. Screening hemodialysis patients by using PWdisperC may facilitate identifying a group of patients with poor prognosis.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Prolonged screening of AF in patients (pts) with cryptogenic stroke (CS) is recommended and electrocardiographic markers of atrial remodeling, like p-wave dispersion, have been described in literature. Electrocardiographic changes in pts with CS to predict AF in the follow up are not well-established. Purpose To identify ECG predictors of AF in a subset of pts with cryptogenic stroke. Methods We prospectively included consecutive pts admitted with CS. A surface 12-lead ECG was performed at admission, recorded at 25 mm/second and 10 mV/cm with commercially available imaging system. P-wave analysis of maximum (P max) and minimum (P min) duration, p-wave dispersion (PWD, defined as the difference between the P max and P min, being abnormal if &gt; 40 msec) and amplitude were evaluated by a two independent operator. P-wave axis was determined by an automated mode available in the equipment. ROC curve was analyzed to determine the optimal cut-off values. Results We enrolled 105 pts (55.2% males), with mean age of 68.18 ± 8.83 years, 79% had hypertension, 18.1% had diabetes, 44.8% with dyslipidemia, 21% current smokers. During follow up period, 18 pts (17.1%) developed AF. We found that only PWD (AUC 0.706, IC95%: 0.564-0.848, p = 0.006) and P-wave axis (AUC 0.715, IC95%: 0.870-0.860, p = 0.004) were strong predictors of AF. PWD cut-off of 47.50 presented a sensitivity of 77.8% and specificity of 59.8% and P-wave axis cut off value of 75.50 had a specificity of 95.4%. Age (p = 0.032) and current smoking (p = 0.014) were associated with occurrence of AF during the follow up.   Conclusion: PWD and P-wave axis predicted incident AF in this subset of pts with cryptogenic stroke. The ECG may be a toll to identify pts at risk of developing AF, although larger studies are needed to confirm these results. Abstract Figure.

Introduction: Rising evidence suggests that statins have a positive effect on the prevention of occurrence of atrial fibrillation (AF) in hypertensive patients. P-wave dispersion (PWD) has been known to be an electrocardiographic predictor for the development of AF. We therefore aimed to investigate on the possible effects of statins on p-wave dispersion in hypertensive patients. Method: A total of 27 patients (22 females; mean age, 45±11 years) with hypertension and without history of AF were included in this prospective study. P wave durations and PWD, left ventricular mass (LVMI), left atrial volume index (LAVI), and ratio of early diastolic transmitral flow velocity (E) to early diastolic mitral annular velocity (e) (E/e’) were measured and compared before and after statin therapy (simvastatin 40mg/day for 3 months). Results: After 3 months of statin therapy, there was no significant change in PWD (pre-statin 39.7 ±10.7, post-statin 33 ± 8.8, p-value 0.30). Baseline and follow up blood pressure, heart rate, LVMI, LAVI and E/e’ ratio were not significantly different before and after simvastatin therapy. No patient developed AF during follow up. Conclusion: Simvastatin (40mg/day) therapy for 3 months did not show significant change on PWD, LVMI, LAVI and E/e’ ratio in hypertensive patients.
