The person's ECG shows the following characteristics: PR interval .08, QRS .08 and isoelectric ST segment. What do these characteristics indicate?

Question

Quizplus · Accepted Answer

A PR interval of .08 seconds is shorter than the normal range (0.12 to 0.20 seconds), indicating faster than normal conduction from the SA node to the ventricles. A QRS duration of .08 seconds is within the normal range (0.06 to 0.10 seconds), indicating normal conduction through the ventricles. An isoelectric ST segment is considered normal, indicating no significant ischemia or injury at the time of the ECG.
