Can someone make a quick table of home ekg monitoring devices (companies like Kardia). For example, cost? Can I get QTc intervals? What devices does it work on?  What other data does it collect?  This is for COVID trials for older people we want to keep at home. How can we collect health data from them at home- ideally we would be able to measure pulse, resp, temp, EKG?
