Stick-on "Zio" patch diagnoses irregular heartbeat in cardiac patients

It may look like a Band-Aid, but the "Zio" cardiac monitor can help emergency-room patients avoid unnecessary follow-ups, according to a new study by Scripps Health. Developed by iRhythmn Technologies, the 2-by-5-inch patch sticks to the skin like an adhesive bandage. Despite their severity, cardiac arrhythmias happen infrequently and are tricky to diagnose. The "Zio", on the other hand, provides continuous recording of up to 14 days - significantly longer than most heart monitors on the market
