Even though I am a Nurse that works on a telemetry floor I resist taking pharmaceuticals. However, when I developed my arrhythmia as mentioned by so many on this site, I tried their methods so they would not call me a noncompliant patient. Metoprolol gave me chest pain for the 4 days I took it, and could not tolerate it. I had not seen anyone mention Coconut water on this site but this is what I tried. I had been taking Magnesium called “Calm" which I had gotten at my local health food store and I took it when my symptoms were bad. But it was't as natural as food and I wanted a more natural supplement.
This is what I did and noticed: On hot days and sweating a lot, the arrhythmia were much more common afterwards. Also at night when laying down or on my left side it was real common and annoying, many trips to the ER. I bought my own EKG machine cause the doctors were not impressed by my discomfort...Apparently I feel every abnormal beat where many people do not. I started going to bed early to avoid the discomfort of the abnormal beating of my heart. I knew I was in Afib or would have rhythms of 3 quick beats in between normal sinus rhythm causing brief moments of shortness of breath. This is scary not matter how old you are....And at 48 years old they accidentally found an infarct in my brain. I'm not surprised given the abnormal beating of my heart and the confusion I was complaining about. That being said I started increasing foods that thin the blood, but this didn't solve the rhythm issues.
So with my experience on the floor I knew there are many things that can cause abnormal rhythms. Low blood flow to the heart (dehydration) blood pooling in the lower extremities because of standing for long hours (compression hose helps this), Electrolyte imbalances. The body doesn't just sweat out sodium, we loose other electrolytes that needs replacing.
I found that coconut water gives us Calcium, Magnesium, Phosphorus, Natural sugar. All of what Coconut water gives, is what we need for good neuromuscular health. So I started drinking an 8oz bottle a day. Problem solved. The days I forget to drink it, the arrhythmias come back slightly which reminds me I had forgotten. Some people as we get older have more trouble then others holding onto their electrolytes. I'm one of them.
The doctors never figured this out, they just kept giving me supplementation when my potassium dropped. We have to keep a good nutritional balance. Oh yes and Alcohol...This dehydrates and flushes the good stuff out. Its no wonder it can trigger abnormal heart rhythms, along with muscle cramps. Another reason to avoid it. Hope this helps.
