2025 ECG Competition Answers (Part 3/3)
This week we review the answers to questions 10-14 from the 13th Annual UMEM Residency ECG Competition. Make sure to attempt to answer the questions yourself before watching the video…
Escape-Capture Bigeminy
Key Points Escape-capture bigeminy is a unique rhythm characterized by alternating escape beats and normally conducted sinus beats, resulting in a bigeminal (paired) rhythm pattern. It typically occurs in patients…
Junctional Escape Rhythms
Key Points Narrow QRS Complexes typically indicate junctional escape rhythms, originating near the AV node or proximal His-Purkinje system. These generally have a more favorable prognosis. Wide QRS Complexes suggest…
