Sorry to hear about your sister, that's horrible. I absolutely agree that there is a role for these devices in monitoring medical conditions. I have a sister who was born with a tachycardia condition which recurred in high school. I got her one of the Garmin wrist watches with a heart rate sensor so she could monitor the condition over time. Obviously it doesn't fix anything on its own, but it can help to understand the problem and feel more in control.
