(FIT)-Module 1, Workshop 1: Electrocardiographic/Electrophysiologic Correlation-Miller Case 4 Answer

Video Transcription

Video Summary

The patient has hisperkinesia, characterized by an abnormal ECG with right bundle branch block and a normal PR interval, indicating the issue is within the hispokinesis system rather than the AV node. Her ECG shows a second P wave deforming the end of the T wave during sinus rhythm, and her sinus rate increases appropriately during anxious states, ruling out chronotropic incompetence. The conduction problem persists in the hispokinesis system, affecting her heart rate response during exercise, despite normal sinus function.
