Even with tachycardia and a paced QRS duration of ~0.16 In this specific case, Left Bundle Branch (LBB) area pacing was pursued to achieve cardiac resynchronization. (J J Am Coll Cardiol. second I immediately knew there is no way this relative increase in QT duration ( compared to the R-R interval ) is going to be "normal".

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. Hopefully a repeat echocardiogram will be performed outpatient.

EMS reports intermittent sinus tachycardia and bradycardia secondary to some type of heart block during transport. It is hard to make out P waves but you can see them best in V2, and notches in the T waves in other leads - this is a sinus tachycardia with a very long PR interval indicating first degree block.
