Wearable for a cardiac patient.

[DRNewcomb]

I'd like to discuss selection of a wearable device for a cardiac patient. I don't know much about the subject but I suspect that desirable features would be:

• Monitor pulse and blood oxygen
• Notify the wearer when certain conditions occur
• Provide a easy way to call 911

It would be good if this was connected to the mobile phone by BT and did not require its own wireless plan.
I would think that this is a FAQ. I just have not been able to find it.

I believe Verizon did have a device similar to your inquiry, but it has been more than 5 years since I read about it. I don't recall its name at this time. This was something that required a visit to a retail store.
