Heart Failure Pathophysiology and Diagnosis

Pathophysiology In an average healthy person, normal LV ejection fraction (LVEF):  >50% Roughly 50% of those with heart failure have reduced left ventricular (LV) function (HFrEF) Heart cannot squeeze/contract properly, and then progressively dilates. The other 50% have preserved (normal contraction) LV function (HFpEF) Cannot relax properly, leading to high diastolic (filling) pressures. New heart failure – work patient up for ischemic disease (CAD) and ACS … Continue reading Heart Failure Pathophysiology and Diagnosis

Atrial Flutter

More organized, saw-tooth type pattern seen on standard 12-lead EKG. Negative flutter waves in inferior leads Positive flutter waves in V1 Typical Flutter = counterclockwise reentry around tricuspid annulus. Rate is ~250/min; noted as 2:1 or 4:1 for its atrial rate and the ratio of electrical conduction down the AV node. Atrial Flutter is often seen in patients diagnosed with concomitant Atrial Fibrillation (Fib-Flutter). Management Similar to … Continue reading Atrial Flutter

Atrial Fibrillation

It’ll take some time to shake the feeling of being the “Intern” after twelve months with that role.  One of my primary goals for intern year (first year) was to learn the fundamentals of real-world medical practice.  If I had to choose a few from a long-list, some fundamentals would include:  recognize life-threatening and other urgent but common conditions, treatment, and speaking to patients and families about their … Continue reading PGY-2 Life And Decisions

PGY-1 “Intern” Year In Review

It’s time for the obligatory “year in review” post, and I couldn’t be more proud.  Intern year is an emotional rollercoaster, marked by episodes of triumph and failure.  The year is almost over, and I am (anxiously) awaiting my second year of residency training.  Finishing intern year (first year) is a huge milestone in my professional medical career.  Many medical students ask me:  “Any advice for … Continue reading PGY-1 “Intern” Year In Review
