Algorithms and criteria that help clinicians make a proper distinction

In a previous episode of Mayo Clinic’s “Cardiovascular CME” podcast, we discussed what defines a wide complex tachycardia, the importance of arriving at a correct diagnosis, and the underlying motivation for the abundance of manually applied and automated differentiation methods.

In this episode, cardiac intensivist Adam May, M.D., and host Anthony Kashou, M.D., expand on that by examining the principles behind the various differentiation algorithms and criteria that help clinicians properly distinguish wide complex tachycardias.

Specific topics of discussion include:

• Underlying electrophysiologic features to look for when trying to determine the site of origin of a wide complex tachyarrhythmia using the 12-lead ECG.
• The meaning of the term “morphologic criteria” and when it can be helpful in differentiating wide complex tachycardias.
• The value of comparing a patient’s wide complex tachycardia ECG and baseline ECG.
