Sometimes you only learn about the latest technology available by having patients coming in wearing the devices.
For instance, I had no idea there was such a thing as an wearable external defibrillator. This is a device that is worn as a harness on the upper chest. It continuously monitors the heart. It has a built in defibrillator. If the monitoring device senses v fib or v tach (fatal rhythms) it sounds an alarm to warn the patient and then defibrillates them.
It is apparently used for patients with CHF (heart failure) or cardiomyopathy (enlarged heart) who may be too risky for surgery for an internal defibrillator. It can also be used pre insertion of defibrillator.
I've only seen it once. Its amazing whats out there.
