No, the right ventricle is first to depolarize, that is if you're talking about ventricular depolarization (the QRS complex). If not, then it's the right atrium (atrial depolarization, P wave).

The stage of the heart cycle in which the heart muscle contacts and the chambers pump blood?

The sinoatrial node depolarizes the atria and causes them to contract which tops up the ventricles with blood, the signal then moves through the atrioventricular node and then the atrioventricular bundle and into the purkinje fibres which causes the ventricles to depolarize and contract sending blood from the right ventricle to the lungs and from the left ventricle. The Atria repolarizes at the same time as the ventricles depolarize and then a fraction of a second later the ventricles repolarize and the cycle begins again.
