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 ...

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 ...

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 ...
