        Walked it off. About 50% of the time walking will raise the ventricular rate to match atrial rate well enough to result in re-synchronization. The cardiac PLL locks and becomes stable once again.

        Thank-you. Yeah, AF is a PITA. But quality is the watchword and I don't want to provide poor graphs which would misinform. Sometimes it takes three or four measurements to determine what is representative.

        Did you take him home when he was still woozy? I did that... just once. Collapsing cat; head on hard tiled-concrete floor. Worrying.
        After that I always let them sleep it off at the vet.

        He was still feeling the effects of the anesthesia when brought home. One hour trip home helped some. Still, we were careful to monitor his wanderings and confine him to safe spaces with carpet. Your experience sounded positively unpleasant. It helps somewhat that I am in the medical device business and have ER / OR / ICU experience.

        It was unpleasant, and I don't think I handled it well. When stubborn animals like cats have to be caged for hours or a day, it is better for the likes of me to leave it to the professionals.

        No harm done, in the end. The cat concerned made a full recovery.

        Having suffered atrial fib myself and been through a cardioversion (luckily only once myself) as well as having a brother who had to go through an ablation procedure for the same, I really appreciate your work to raise awareness on this issue (and deeply sympathize with what you've had to go through.)

        I hope you are doing much better now!

        @nedifer - thank-you, new med regimen appears to be working though the side effects are ... challenging. Had a flutter ablation (right atrium) last year. I wouldn't wish this on anyone. Hopefully you and your brother are also doing well. Stress is one of my triggers, listening to calming music a powerful counter measure.

    See information section for my opinions
    My enjoyment of particular recreational music systems is inextricably intertwined with my personal preferences. The following lists are representations of my tastes in music, components and listening levels. The section on music is only a sample of my library but should provide sufficient insight into my musical preferences. I am rigorous and exacting with component measurements. That doesn’t automatically make my opinions worth anything without context. Use the following information to decide how well your own preferences converge or diverge with mine when I make comments about equipment in the forum. DO NOT blindly assume a positive comment from me about some component or headphone will automatically translate to auditory happiness on your part. Likewise you may find yourself enjoying something that I don’t. Consider (learning) your own personal preference.

    I tend to listen at quieter levels where electroacoustic transducers exhibit greater linearity. Higher levels are more likely to have greater distortion and require higher power amplification. The result is substantial deviation in opinions by listeners attempting to compare headphones when they are listening at different levels.
