Pre-excitation Index
Pre-excitation index is a useful measurement to confirm the presence of an accessory pathway mediated tachycardia and identify the side of the accessory pathway
Entrainment – 4
In this section we will look at some real life tachycardia circuits and see how the principles of entrainment and the criteria can be applied.
Entrainment – 3
In this section we will look at concepts behind the so-called entrainment criteria
Entrainment – 2
In this section we will see the importance of continuous pacing for entrainment
His synchronous PVC
This is a very elegant technique to detect the presence of an accessory pathway during narrow complex tachycardia.
Entrainment – 1
In this section we will put single extra-stimuli to understand the concept of post pacing interval and how to use it to to identify a location in relation to a re-entrant tachycardia circuit.
Differential Pacing for accessory pathways
Differential pacing is another maneuver complementary to parahisian pacing which we can apply in sinus rhythm to look for accessory AV connections (accessory pathways)
Parahisian Pacing
Parahisian pacing is a maneuver which we can apply in sinus rhythm to look for accessory AV connections (accessory pathways)
