An ECG of a healthy subject has the following elements:
-positive waves P, R, and T,
-negative waves Q andS; the positive wave U is accidental;
-P-Q, S-T, T-P, and R-R intervals;
-QRS and QRST complexes.
Each of these elements characterizes the time and sequence of excitation of various parts of the myocardium.
