(FIT)-Module 3 Workshop 5: Invasive and Non-Invasive Correlation-Marchlinski Workshop 5

Marchlinski Workshop 5

Pdf Summary

The document provides a series of workshop questions and their answers related to electrophysiology. Workshop #5, led by Dr. Francis E. Marchlinski, focuses on various case studies and their related questions. In Case 11, tracing 11-1 is analyzed to determine the most likely diagnosis, with the correct answer being Mobitz I AV block present due to HPS disease. In Case 12, tracing 12-1 is shown, and the likely origin of a non-PV trigger is deduced to be the superior posterior wall of the left atrium. Case 13 involves the analysis of a 12-lead ECG to determine the likely site of origin of PVCs after PV ablation, with the correct answer being the right coronary aortic cusp. In Case 14, tracings following adenosine administration are examined, showing conduction from the left inferior PV to the surrounding left atrium. Case 15 focuses on an ECG tracing showing electrical alternans, which is determined to be due to pericardial effusion. Case 16 involves adenosine administration and observations of conduction patterns in the left superior and left inferior PVs. The correct answer is conduction from the left inferior PV to the surrounding left atrium. Finally, Case 17 analyzes tracings from burst and steady-state pacing to determine the most likely arrhythmia mechanism, which is determined to be bundle branch reentry VT. Each case study provides a brief explanation and analysis of the tracings to arrive at the correct answers.
