Marathon Runner Needs Preoperative Work-Up

ANSWER
All measured intervals are within normal limits; there is a P wave for every QRS complex and a QRS complex for every P wave. There is no evidence of injury, ischemia, or infarct, and no atrial or ventricular hypertrophy.  This is, in other words, a normal ECG—and is that of the author.

Perioperative ordering of ECGs based on patient age, in the absence of prior heart disease, remains controversial. In the majority of cases, identification of abnormal findings does not occur. However, as long as previously unknown anomalies are discovered, this practice will likely continue.
