Quercetin and Arrhythmia

  • Quercetin and Arrhythmia

    I have longstanding cardiac issues. Heart attack in ’08, CVD, leaky valve, enlarged aorta, frequent ectopic beats.

    A few weeks ago I experienced a four-day episode of atrial fibrillation. I have never suffered this before and I put it down to extreme stress (my wife has advanced ovarian cancer). I was prescribed oral blood thinners but I am reluctant to take them.

    Incidentally, I bought my wife some Quercetin as it is reputed to have anti-cancer effects. However, she decided not to take them. Because Q is also thought to offer benefits for heart health, I decided to give them a try simply for general health benefits.

    I had also bought a Wellue O2 Ring, to monitor my SPO2 while asleep, because I was asleep when the AFib started. The O2 ring showed that I was experiencing many severe SPO2 drops through the night, as low as 88%. These would wake me up gasping and with a thudding heart. I have had these for many years and assumed they were apneas, though my CPAP machine never showed anything coinciding with these events.

    Within two days of commencing the Quercetin, the low SPO2 episodes while sleeping literally stopped. Zero. Nada. Zilch. The data from the O2 ring is quite startling, up and down all over the place until I started the Quercetin than flat with excellent SPO2 scores. This has continued until today, over two weeks later. Fingers crossed this persists.

    I had my annual stress echo test a couple of days ago and asked my cardiologist for his views on Quercetin. Despite being a professor of cardiology with many decades of experience, he claimed to have never even heard of Quercetin, much less have an opinion on it!

    Far too many health specialists today have ‘tunnel vision’, focused totally on whatever the mainstream doctrine is in their field.

    Thank you for sharing your info. My sister has CVD, a leaky valve, and recently had her pacemaker replaced. The pacemaker keeps her alive. She has had really low O2 readings when she wakes up like the mid 80’s and the O2 Ring sounds like it would be a good tool to help her determine if she needs some sort of therapy. She is on standard Warfarin therapy and her cardiologist was adamant against substituting nattokinase when I suggested a change. I don’t have any health issues and I have been taking quercetin for about a year every other day alternating with a low dose of IVM. I’m thinking my sister would benefit from taking a standard 500 mg dosage to start. But I would like her to monitor her O2 levels prior to adding a new supplement. Your sample size of one is a good data point and hopefully my sister can verify the effect of quercetin on her O2 levels as well. Thanks again for sharing.
