Imagine you're on a remote ranch, in the middle of the night, when a pain strikes. It's probably indigestion, but you wonder whether it might be your heart. Before telemedicine, you had three options: Drive many miles to an emergency room. Dial 911 and wait for the rescue squad. Return to bed and hope for the best.
Telemedicine offers a fourth option. On your smartphone or tablet, click on a “telemed” app. In a minute or so, talk eye-to-eye with a doctor.
