Relationship between simple electrocardiographic parameter and paroxysmal atrial fibrillation.

Area of Science:

• Cardiology
• Electrophysiology
• Medical Diagnostics

Background:

• Atrial fibrillation (AF) is a common arrhythmia requiring accurate prediction to mitigate complications.
• Investigating simple P wave parameters offers a potential method for predicting paroxysmal AF (pAF).

Purpose of the Study:

• To explore the relationship between basic P wave electrocardiogram (ECG) parameters and the occurrence of paroxysmal atrial fibrillation (pAF).

Main Methods:

• A case-control study design was employed.
• Demographic and laboratory data were collected using a checklist.
• P wave parameters were measured via ECG, and their association with pAF was statistically analyzed.

Main Results:

• The study included 80 participants (40 with pAF, 40 controls).
• Longer P wave peak time (PWPT) in leads D2 and V1 was observed in the pAF group.
• Prolonged PR interval (PR) in D2, P wave duration (PWD) in D2, and P terminal force (PTF) in V1 were linked to increased pAF occurrence.
• Adjusted regression identified PWPT in V1 and PWD in D2 as significant predictors of pAF.

Conclusions:

• Simple ECG parameters, particularly PWD in lead D2 and PWPT in V1, show promise for predicting and assessing pAF risk.
• These findings are valuable for clinical risk stratification, especially in patients without structural heart disease.
• The results may aid in preventing complications associated with pAF.
