It is the name for the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG). It is usually the central and most visually obvious part of the tracing. It corresponds to the depolarization of the right and left ventricles of the heart.

The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.

What is it called when there are no QRS waves following p waves?

The QRS complex and the P wave are features of the electrocardiogram, which graphically displays the electrical activity of the heart. The P wave is generated when the atria, or upper chambers of the heart contract. The QRS complex is generated when the ventricles or lower chambers of the heart contract. If there is a P wave but no QRS, the the heart's main pump is not functioning. This would cause death quickly.
