Does a new 12-lead ECG P-wave algorithm accurately predict the site of origin of focal atrial tachycardia?
A novel 12-lead ECG algorithm based on P-wave polarities accurately predicts the site of origin of focal atrial tachycardia in 90% of cases, potentially guiding ablation strategy.
Qian et al. (2010) conducted an observational in Focal atrial tachycardia (n=91). P-wave diagnostic algorithm was evaluated on Correct identification of the site of origin. A new P-wave diagnostic algorithm correctly identified the site of origin in 90% of focal atrial tachycardia cases.
