Workshop 5: Invasive and Non-Invasive Correlation (Michaud)

Video Transcription

Video Summary

The video transcript discusses different cases in electrophysiology (EP). In the first case, a telemetry strip shows an episode of supraventricular tachycardia (SVT) termination. The video explains that it is likely an orthodromic reciprocating tachycardia (ORT) utilizing a slowly conducting left-sided accessory pathway. In the second case, the integrity of roof and anterior mitral lines is being tested. The video concludes that neither line is blocked based on the timing and conduction observed. Finally, in the third case, a tracing obtained during atrial pacing suggests antedromic atrioventricular (AV) re-entry as the most likely diagnosis. The video explains that the QRS complexes remain fixed until the tachycardia terminates with atrial pacing. These cases highlight the importance of careful observation in EP studies to determine the underlying mechanisms of arrhythmias.
