ECG Analysis of Pre-excitation (WPW) without algorithms
Analysis of delta wave pattern on the ECG can give clues as to the location of a given accessory pathway. Such analysis can be done without algorithms if you read the ECG in a logical sequence.
Effect of Bundle Branch Block on AVRT
Bundle branch block during orthodromic reciprocating AV reentry tachycardia (AVRT) helps to determine the side of the accessory pathway
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
His synchronous PVC
This is a very elegant technique to detect the presence of an accessory pathway during narrow complex tachycardia.
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)
