Clevidipine is a drug used as an infusion for severe hypertension or patients who require narrow blood pressure parameters.
Exercise Stress ECG: ST-segment changes
ST-segment changes on Exercise Stress ECG. Learn to recognize significant ST segment changes on the ECG (EKG).
Medmastery: Qualifying for an ICD
Which conditions qualify a patient for an ICD implant? What is the difference between primary and secondary prevention?
ICD: ICD vs brady pacemaker
Medmastery ICD Essentials course. Implantable Cardioverter Defibrillator (ICD), and how they differ from brady pacemakers.
Echo: Left ventricular systolic function
Helen Rimington of Medmastery on assessing left ventricular global systolic function
Echo: Pericardial effusion
Helen Rimington explores the Echocardiography Essentials course with a video demonstrating rapid bedside assessment and diagnosis of pericardial effusion.
Echo: Mitral regurgitation
Helen Rimington Medmastery course with assessment of mitral regurgitation and cardiac decompensation following rupture of a cord in mitral valve prolapse
Echo: Aortic regurgitation

Right Ventricular Failure
Right Ventricular Failure: Unrecognised high mortality equal to that of LV failure. Right heart is a low-pressure system, good at dealing with volume (preload) to a point, does poorly with increased afterload (i.e. PH).
Henry Bazett
Henry Cuthbert Bazett (1885 – 1950) was an English physiologist. Eponym: Bazett's formula to calculate QTc interval for varying heart rates
Bazett formula
Bazett formula 'corrects' the measured QT interval to a value (QTc) attributable to a heart rate of 60 bpm. Thus providing a QT interval value that a particular patient would theoretically have if their heart rate was 60 beats/min
