After his heart surgery last week I ordered him one. He wore it all week and noticed at home his Heart Rate was high again. He tracked it and called his cardiologist. "Go back to the ER." Sure enough the FitBit was right. His heart rate was at 177. Like he ran a marathon.
This morning they shocked his heart again to get back into rythem. His doctor told him this device saved his life.
For those who don't know what a Fitbit is its a watch like tracking device that you wear like a watch and it tracks your steps, heart rate, sleep patterns etc. It's extremely inexpensive. I got him the Fitbit Charge HR off Groupon. https://www.groupon.com/deals/gg-fitbit-charge-hr-wireless-activity-wristband
