Answer to Question 1

1
The small square on the ECG graph paper equals 0.04 second. The large square equals 0.20 second. The PR interval is 0.12 to 0.20 second. Two large squares would be equal to 0.40 second.

Answer to Question 2

4
A U wave is not always seen and can be very small. It can indicate electrolyte imbalance, medication effects, and ischemia. The P wave, QRS complex, and T wave are normally seen in the electrocardiogram tracing.
