P waves of high CT-originated AT always showed ... The algorithm incorrectly suggested a high CT location for a tachycardia originating in the SVC, a parahisian location for a tachycardia at ...

A narrow complex tachycardia results with P wave morphologies that are different than normal sinus P waves. The QRS complex can be wide if aberrancy is present (ie, right or left bundle branch ...

Sinus tachycardia is recognized on an ECG with a normal upright P wave in lead II preceding every QRS complex. This indicates that the pacemaker is coming from the sinus node and not elsewhere in ...

Factors that Influence the Ability of Pacing to Interact with Tachycardia In order for pacing stimuli to terminate reentrant VT they must first interact with the VT circuit. Josephson [2] has ...
