(FIT)-Module 1, Workshop 1: Electrocardiographic/Electrophysiologic Correlation-Tomaselli Case 2 Question

Video Transcription

Video Summary

The question is asking about the factor most likely contributing to changes in an ECG related to the right ventricle. The options focus on different ion current gradients across the right ventricle: sodium, transient outward potassium, calcium, and inward rectifier IK1 currents. Each of these ion currents can influence cardiac electrical activity and may lead to observable changes on an ECG, such as alterations in conduction, repolarization, or depolarization patterns. Understanding the specific characteristics of these ion currents and their effects is crucial to selecting the most relevant option.
