(FIT)-Module 2 Workshop 3: SVT Mechanisms and Maneuvers-Stevenson Workshop 3

Stevenson Workshop 3

Pdf Summary

In this document, the focus is on differentiating between different mechanisms of supraventricular tachycardia (SVT) through various pacing maneuvers. The document includes several case studies with accompanying tracings and questions about the most likely tachycardia mechanism based on the findings. The pacing maneuvers discussed include ventricular pacing, atrial pacing, and para-His pacing. These maneuvers are used to assess conduction properties in the AV node, accessory pathways, and atrial tissue.<br /><br />The document emphasizes the importance of differentiating between atrial tachycardia (AT) and AV nodal reentry tachycardia (AVNRT) as the most common SVT mechanisms. Ventricular pacing is particularly helpful in distinguishing between these two mechanisms. It is also noted that a nodal response during para-His pacing can exclude certain types of accessory pathways.<br /><br />The document provides explanations and answers for each case study, outlining the specific findings and the resulting diagnosis. It highlights the importance of studying the timing and conduction patterns in order to determine the mechanism of the tachycardia.<br /><br />Overall, the document serves as a reference for clinicians and researchers studying SVT and provides insights into the use of pacing maneuvers in diagnosing different mechanisms of tachycardia.
