Is defensive medicine reaching the NBA?
Cardiologist Dr. Barry Maron of the Minneapolis Heart Institute Foundation told ESPN.com that he will recommend to team doctors that every team replace the standard electrocardiograms (EKGs), which can detect an irregular heartbeat, with echocardiograms, an ultrasound that allows a doctor to study the size of the heart and the strength of the heart muscle.
Echocardiograms, which are not invasive and are not in any way perceived as harmful, cost at least three times as much as EKGs.
