Electrocardiography, Dr. D. Penney





Table 16. ANALYSIS OF ELECTROCARDIOGRAMS
_________________________________________________

1) Scan sequence of the waves:
First identify waves; wave of highest amplitude is usually the R wave; T wave consistently follows R wave; P wave should precede R wave.

2) Heart rate & duration of waves & segments:

Bradycardia <60 per min. (normal in athletes)
Tachycardia 100-220 per min. (normal in exercise / stress)
Flutter 220-350 per min.
Fibrillation - not defined by rate; too chaotic
