Spectrum of congenital heart disease
Congenital Heart Disease (CHD) Shorts
You said, and we did! Past students provided us with feedback that we need to update our resources for the Congenital Heart Disease portion of the Cardiovascular Unit, and after many hours of labor, we are pleased to present you with the CHD Shorts video series. This series will take the student through the foundational […]
Tips for reading ECGs
ECG physics An ECG is a recording of the heart’s electrical activity. Electrical current moving toward the positive electrode causes positive deflection. Electrical current moving away from the positive electrode causes negative deflection. The stronger the current, the stronger the deflection. All 12-lead ECGs are 10 second strips. The amplitude (vertical distance) of the deflection […]
