This week we have a series of 3 ECGs from separate patients. These patients all had the same question. “Doc is my pacemaker pacing properly?”

Patient 1 78yr female presents following a mechanical fall. Her CXR shows likely left side nondisplaced rib fractures. The patient is worried that the fall may have dislodged the pacing leads. What will you tell her?

Patient 2 is a 65yr female who presents with chest pain. What is on her ECG?

Patient 3 75yr female presents with renal colic and complains of chest palpitations during periods of pain. Her ECG is below:

They say things come in 3s, I hope you enjoy todays trifecta of ECGs!
