P wave represent the electrical impulse across the right and left atrium. It travels across the atrial wall. Qrs complex indicates the electrical impulse through the myocardial ventricles. It travels through the bundle of HIS (GOD), right and left bundle branches and then across the right and left ventricular walls.
Okay so an EKG show the electrical impulse that travels through the heart. What I mean is EKG don't show contraction. However the QRS complex represent ventricular depolarization, which signals ventricular contraction

what does isoelectric line represent
The P wave represents atrial depolarization (they contract). In a normal EKG, the P-wave precedes the QRS complex. It looks like a small bump upwards from the baseline.
by largest, I'll assume tallest. the tallest wave on an EKG is called the QRS complex and represents the contraction of the left ventricle. btw tallest could also mean lowest depending on the particular ekg lead.
The EKG or ECG components are the P wave (contraction of the atria), the QRS complex (the contraction of the ventricles) and the T wave (repolarization of the ventricles).
With mild elevation in potassium there is a reduction in the P-wave, and a peaking of the T-wave. With severe elevation in potassium there is a widening of the QRS complex.
QRS complex
The T wave in an ECG is typically in the same direction as the QRS complex because both represent ventricular depolarization and repolarization, respectively. During the QRS complex, the ventricles depolarize, and then during the T wave, they repolarize, leading to the similar orientation of the waves.
On the EKG readout the P Wave represents atrial depolarization. For a healthy person it should be smooth, round and upright, and preceding the QRS complex.
The P waves represent the electrical activity that causes the atria to contract in the heart. They occur before the QRS complex on an electrocardiogram (EKG) and signify the depolarization of the atria.
