Signal processing of the electrocardiogram (ECG) was performed during supraventricular tachycardia (SVT) in 24 patients in an attempt to locate the P wave and to characterize its morphology in three orthogonal planes. In patients with atrioventricular reciprocating tachycardia, a discrete atrial signal could be identified within the ST segment and/or T wave with inferior-to-superior orientation. Atrial activation was identified in patients with primary atrial tachycardia as long as there was a… CONTINUE READING
