Once you find out your heart is structurally sound, then you can know that it's the infections causing this. Hopefully then you can relax just a bit more about
it. I know it's scary though - I've had some heart symptoms too.
As for the detoxing, you have a good start! And an Infrared sauna would be a really good addition! You can also add in oil pulling, activated charcoal or other binders (remember to keep these 2 hours away from food/meds), the days you aren't using a detox soak, and many have found great relief from coffee enemas, to name a few more things.
Remember that as these bacteria die, the release toxins, so as you continue to treat, you need to be sure that you are doing all you can to detox.
And I took my kitchen timer in the bathroom with me when I did a detox soak.
