Heart Murmurs FREE
Systolic vs diastolic, the Big Four, maneuvers, and HOCM, the exception that always shows up.
Diastolic Rumble 🔒
The low-frequency murmur of mitral and tricuspid stenosis. Where to listen, what it means.
Paradoxical S2 Split 🔒
Reversed splitting in aortic stenosis and LBBB. Why expiration widens the gap.
Wide S2 Split 🔒
Pulmonic stenosis, RBBB, and ASD. Fixed split vs physiologic widening on inspiration.
Mitral Regurgitation 🔒
Holosystolic at the apex, radiates to the axilla, louder with hand grip. AFib and surgery follow.
Inferior MI + AV Block 🔒
RCA occlusion hits the inferior wall, the AV node, and the RV simultaneously. Why nitro kills.
MI ED Meds: MONA-BAH 🔒
Morphine, oxygen, nitrates, aspirin, beta-blockers, ACE-I, heparin. The ED bundle.
Post-MI Complications 🔒
V-fib in hours. Walls rupture in weeks. The timeline boards always test.
Hemodynamics 🔒
CO, preload, afterload, Frank-Starling, PV loops, valve lesion parameters, hypertrophy patterns, shock classification, and SVR/PVR.
Lead I: RA to LA 🔒
The lateral lead vector, what it sees, and how to use it for axis deviation.
Antiarrhythmics FREE
Vaughan-Williams classes I to IV. Sodium, beta, potassium, and calcium channel blockers, plus amiodarone's thyroid and lung toxicity.
Cardiomyopathies FREE
Dilated vs hypertrophic vs restrictive. HOCM murmurs that worsen with Valsalva, and the cardiac causes of sudden death in young athletes.
