Key result
In patients with secundum atrial septal defect, P-wave peak time in lead DII (PWPTDII) was significantly correlated with P-wave dispersion (r=0.355, p<0.001), PR interval, and interatrial block.
Why the study?
Multiple electrocardiographic parameters are useful in predicting AF in secundum ASD, but whether PWPT correlates with other P wave indicators in ASD patients without right heart failure was unknown.
Does P-wave peak time duration correlate with established indicators of atrial fibrillation risk in patients with secundum atrial septal defect?
Observational (n=96)
No
Does P-wave peak time duration correlate with established indicators of atrial fibrillation risk in patients with secundum atrial septal defect?
Effect estimate: r=0.355
p-value: p=<0.001
P-wave peak time in lead II correlates significantly with established electrocardiographic and echocardiographic markers of atrial remodeling, suggesting it may serve as a novel indicator for atrial fibrillation risk in patients with secundum atrial septal defect.
May aid AF risk stratification in secundum ASD; hypothesis-generating, requires prospective validation.
Aim: It has been determined that many electrocardiographic parameters reflecting atrial remodeling and electrical heterogenity such as p wave dispersion (PWDis), p wave maximum duration (PWDmax), interatrial block (IAB), PR interval are useful tool in predicting the development of atrial fibrillation (AF) in patients with secundum atrial septal defect (ASD). We aimed to investigate whether P-wave peak time duration (PWPT), a new electrocardiographic parameter that reflects atrial remodeling and electrical heterogeneity, correlates with other P wave indicators in ASD patients without right heart failure.

Gül et al. (2021) conducted an observational in Secundum Atrial Septal Defect (n=96). Secundum Atrial Septal Defect vs. Healthy adults was evaluated on Correlation between P-wave peak time in lead DII (PWPTDII) and P-wave dispersion (PWDis) (r=0.355, p=<0.001). In patients with secundum atrial septal defect, P-wave peak time in lead DII (PWPTDII) was significantly correlated with P-wave dispersion (r=0.355, p<0.001), PR interval, and interatrial block.
