I have had paroximal atrial fibrillation for seven years, probably once a month, with HR around 150 for many hours. Over the years I have experimented all possible methods for stopping AF, including electrical tragus stimulation, slow breathing, alternate nostril breathing, swallowing big mouthfuls, vibrating my vocal cords by loud talking . All of them sometimes work, sometimes don’t. But to my great surprise I got today back into SR using a piano metronome. I had read in this forum about “entraining” your heart listening to other people’s hearts.
I wanted to check the method. I used an electronic metronome, because I wanted also a big sound. I think I had bought the metronome years ago around 15 euros. Since by experience I know that when I go back to sinus rhythm I go from about HR 150 to HR 70-80, I set it at 75.
I put it in front of me at maximum volume and with a visual oscillating needle
marking the time (practically all of them have one). I had been for 9 hours in
fibrillation. To my astonishment in half a minute I was back into SR. Not only; since I was connected to a cheap ECG machine (Contec PM10), I noticed that every beat on the metronome corresponded to a peak R on the ECG! Please would a willing colleague repeat the experiment?
