Why the study?
Can P-wave morphology on a 12-lead surface ECG localize the site of focal atrial tachycardia?
Can P-wave morphology on a 12-lead surface ECG localize the site of focal atrial tachycardia?
The 12-lead surface ECG, specifically P-wave morphology, remains an important tool for localizing the origin of focal atrial tachycardia prior to ablation.
Supports P-wave morphology for focal atrial tachycardia localization; confirms utility but leaves open prospective validation.
Focal atrial tachycardia is an unusual form of supraventricular tachycardia arising from defined anatomic locations and sites within the atria. Although recent advances in mapping technology have facilitated successful ablation, the surface ECG remains an important aid in localizing the focus. This review discusses the use of P-wave morphology on surface ECG to localize the site of focal atrial tachycardia.
