Went to hospital having a rapid heartbeat and feeling faint.

RVR would definitely be at play if the ECG shows a rate much above 100. Some people have fibrillation at rates as low as 75-80, as shown by the ECG graphic. This means the ventricles are only getting their usual signal. When a person knows they are fibrillating or in SVT, but their assessed HR is between about 105-200, it's a distinct sign that 'rapid ventricular response' is happening, and that's not good long term. No more than 24 hours, and if it goes that long, get to an ER for help.

@gloaming Thanks for the correction on RVR. Rapid Ventricular Response rather than Rhythm. I had an episode of rapid heartbeat and then Afib I had a few months ago and the clinical notes stated that I was experiencing RVR. Diltiazem IV lowered the heartrate and with it the RVR and the return to sinus rhythm. Since that episode I have found that I can put myself into and out of Afib almost at will. Eating something that has a high level of sugar content can kick me into Afib. Sitting and doing deep breathing exercises for about 10 minutes and back to sinus rhythm. Some modes of exercise such as heavy lifting (stacking hay bales) can kick me into Afib. Sitting and resting and again deep breathing exercises and back to sinus rhythm. Afib never lasts for more than 10 minutes or so. Contemplating a return to the electrocardiologist for another round of PFA. Or possibly a catheterization procedure to see if a blockage may be causing low blood flow which can trigger Afib.
