Hypertrophic Cardiomyopathy
Results:
Hypertrophic Obstructive Cardiomyopathy (HOCM)
Key Points Definition and mechanics: Genetic hypertrophic cardiomyopathy with asymmetric LV hypertrophy, typically septal, causing dynamic LVOT obstruction from systolic anterior motion (SAM) of the mitral valve. Gradient worsens when…
Yamaguchi Pattern: Apical Hypertrophic Cardiomyopathy (ApHCM)
Key Points Definition and mechanics: Hypertrophic cardiomyopathy variant with maximal hypertrophy at the LV apex (apical HCM, ApHCM). LVOT is often not obstructed at rest; some patients have mid-ventricular obstruction…
Not Your Usual STEMI: High Voltage and Narrow Q Waves
A 16-year-old male is referred to the emergency department from a primary care clinic with concern for STEMI. He has no known past medical history. At the clinic, he reported…
2024 EM Boards ECG Review (Part II/II)
A 55-year-old man with a known left bundle branch block presents to ABEM general hospital with acute chest pain. Vital signs are normal and his pain is slightly improved with…
STAT ECG Diagnoses: high left ventricular voltages and ‘dagger like’ Q waves
A 20-year-old man presents with nonspecific chest pain. His history and physical exam are unremarkable. The following ECG is obtained:
Differential Diagnoses: life threatening causes of syncope
A 31-year-old woman presents to the ED after a syncopal episode. She reports feeling palpations daily for the past 1-2 weeks, but is now asymptomatic and well appearing. The following…
