I have a friend out in Sycamore who has sinus tachycardia (and most likely coronoavirus). His doctor wants him to wear a heart monitor, but there are none available in his area (because he's not sick enough). Does anyone know where he can go to get one? I'm happy to pick it up and deliver it to his doorstep. His heart rate is stuck at 120 bpm and goes up to 150 bpm (it's hard for him to sleep). Even if it's a referral to another doctor who may be able to help him, that would be helpful.
