In brief: Sinus rhythm

Sinus rhythm is the normal rhythm of the heart.
It is produced by depolarization of cells in the 'sinus node' of the right atrium. The signal goes from there around the heart. It first depolarizes the atria and causes P wave and the passes into the ventricles and causes the QRS and T waves. This usually happens at a rate of 60-100 beats a minute.
