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 ...

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 ...

For people who suffer from a rapid heartbeat condition called tachycardia, an implanted device can usually nudge the racing blood pump back into a normal rhythm by applying electrical pulses to the ...

Tang et al. developed an algorithm to distinguish left and right atrial foci, and pioneered the prediction of focal ATs using surface P waves. [10] They reported that a positive P wave in lead V1 was ...
