Draw a normal ECG pattern. Label and explain the significance of its deflection waves.

A varsity athlete went for their physical, which included an ECG. The doctors noticed that the student’s heart rate was unusually low, but they told the student not to worry. What term would the doctors include in their chart to describe the student’s heart?

Explain what each of the following terms represents on an electrocardiogram (ECG).

a. P wave

b. QRS complex

c. T wave

d. P-R interval

e. S-T segment

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

d. The ventricular ejection phase generally correlates with the S-T segment and the T wave on the ECG.
