Most wide QRS complex tachycardias (WCTs) are ventricular or supraventricular in origin, but to differentiate between the two can present a diagnostic challenge. To develop and test an algorithm that ...

The retrospective study population included 61 patients (29 men) with a mean age of 42 ± 5 years. Echocardiography showed normal LA (33.4 ± 1.5 mm) and normal ejection fraction (63.1 ± 2.3%). Two ...

Background: Only a few algorithms for predicting the site of origin of focal atrial tachycardia (AT) have been reported. We aimed to develop a new and more effective algorithm. Methods: Surface ...
