Shortening time to stroke treatment using ambulance telemedicine: TeleBAT.

Objective: Patients with ischemic stroke treated with tissue plasminogen activator (rt-PA) have better outcomes when treated closer to the time of symptom onset and within the 3-hour window. We previously demonstrated the clinical use of TeleBAT, a mobile telemedicine system for stroke. We tested the impact of that system on time to treatment for patients with acute stroke.
