QRS in the context of cardiovascular health has reference to the electrical pattern of the heart. This is readily seen on an ECG (electrocardiogram). The Q wave is the first downward deflection after a P wave, the R wave is the first upward deflection following a P wave, and the S wave is the downward deflection following the R wave. Taken together the QRS complex represents the electrical activity of the heart during systole: the phase of the heart during which ventricular emptying occurs.
