Cardiac Physiology and the ECG - Weebly

Peaked/tall: Right atrial hypertrophy. Notched/broad: Left atrial hypertrophy. Does every P wave have a QRS complex. Check The PR Interval: start of P wave to start of QRS complex. 3-5 small squares (0.12-0.2s) Is the interval constant? Check the QRS complex: start of the R wave to the end of the S wave < 0.10 seconds (2.5 squares) ................
