(FIT)-Module 4 Workshop 6: Electrocardiographic and Electrophysiological Correlations-Gerstenfeld Workshop 6

Gerstenfeld Workshop 6

Pdf Summary

This document provides summaries of several cases discussed in a workshop on electrocardiographic and electrophysiological correlations. Each case presents a patient's medical history and includes an electrocardiogram (ECG) tracing. Participants are asked to identify the mechanism for the observed rhythm change or to determine the best management option for the patient.<br /><br />In Case 1, a woman with rapid palpitations was given an intravenous medication, possibly adenosine, which caused high-grade heart block and conversion of atrial flutter to atrial fibrillation.<br /><br />Case 2 involves a man with a history of myocardial infarction who presented with chest pain. The best management option for this asymptomatic patient was not specified.<br /><br />Case 3 describes a man with post-infarction cardiomyopathy who experienced recurrent shocks from his implantable cardioverter-defibrillator (ICD) for ventricular tachycardia (VT). During an electrophysiology study, overdrive pacing induced VT, and the participant had to determine the classification of a low voltage mapping catheter site.<br /><br />In Case 4, a woman with symptomatic premature ventricular contractions (PVCs) was considered for catheter ablation. Activation mapping showed early RVOT sites, as well as early sites in the anterior interventricular vein (AIV) and left coronary cusp (LCC).<br /><br />Case 5 asked participants to determine the best settings for radiofrequency energy application to create the deepest lesion.<br /><br />In Case 6, a woman with a history of hypertension and recurrent chest pain and syncope was shown two ECG tracings. Participants had to identify the medication that was most likely to prevent future syncopal events.<br /><br />The document concludes with a thank-you note.
