The Big Give The VCHS Foundation giving station will be set up at VCHS on March 13 and 14 from 10:00 AM - 1:00 PM in the Courtyard Grille. We will be working towards raising funds for a new EKG machine. An electrocardiogram (EKG) machine measures the electrical activity of your heart. It can help diagnose heart conditions like arrhythmias, heart attacks, and heart failure.
