In the field

“I am a practicing Certified Registered Nurse Anesthetist with some hearing loss and this is an excellent tool to have for the perioperative environment. I have picked up on Afib undiagnosed in the preop area with the EKG feature in a patient who had documented sinus rhythm on their preop EKG.”
