P represents the contraction of the atrial walls, so it rrepresents the excitation wave sweeping ovr the atrial walls in response to which they contract. Q,R and S represent the wave sweeping ovr the ventricular walls which cause them to contract, and T represents the rrecovery of the ventricle walls. there is explaination on dis on Pg 170 in the AS bio book by Mary jones, Dennis taylor, richard fosbery and jennifer gregory.
