Implication

May aid ECG arrhythmia analysis; leaves open prospective validation before clinical adoption.

Key Points

To develop and evaluate a patient-adaptive, knowledge-based P wave detection algorithm that tracks the PP rhythm to identify atrial activity in the presence of various cardiac arrhythmias.
Engineered an automated P wave detection algorithm incorporating domain knowledge and patient-adaptive PP rhythm tracking.
Tested the algorithm across 12 records from the MIT-BIH arrhythmia database, including normal sinus rhythm alongside ventricular and supraventricular arrhythmias.
Achieved an overall sensitivity (Se) of 96.60% and precision (Pr) of 95.46% across all evaluated ECG records.
Demonstrated Se = 97.76% and Pr = 96.80% in normal sinus rhythm, and Se = 72.79% with Pr = 99.51% in Mobitz type II atrioventricular block.
Maintained strong performance during trigeminy and bigeminy rhythms, though detection proved more difficult during complex supraventricular and ventricular tachycardias.
