Lesions in the anterior internodal tract and Bachmann's bundle significantly altered P wave duration, polarity, and morphology, while lesions in the posterior internodal tract had no significant effect.

Overview

Highlights anterior internodal tract role in canine atrial activation; leaves open relevance to human P-wave analysis and arrhythmias.

Structured PICO

P
Population
Canine heart model
I
Intervention
Discrete surgical lesions in selected portions of specialized atrial tracts (anterior internodal tract, Bachmann's bundle, posterior internodal tract)
O
Outcome
Changes in polarity, morphology, and duration of P waves, and conduction time to selected atrial sitessurrogate

Specialized atrial tracts are functionally important in determining the sequence of atrial activation and resulting P wave characteristics in the canine heart.
