opiestrer (@opiestrer) Sorry, I don't have the Apple watch you mentioned. But
I'm desperate to know ... what is the "vagus nerve valsalva maneuver" that you use that has been so successful for you? I'm sure other readers would like to know as well. I have tachycardia and some AFIB, but the vagus nerve valsalva maneuvers I tried never worked for me. Thanks in advance.
