Tapeworm in heart and brain

Everyone, I am a newbie here but have been reading nights and nights about parasites. I suspect I have some big parasite inside me - possibly my heart and behind ears (brain?). I got diagnosed with Blastocystis a while back and tried to get rid of it with herbs. I tried and failed. A year ago my heart started skipping heart beats or suddenly raise at 240p.m. Very scary. Having spent 5 times in the ER I was released with anxiety. Around the same time my dizziness started and has been there ever since 24/7. I tried to put my family and myself on a regular deworming schedule with Vermox but the first time I took it I felt that I had spread my parasite into my head. I could literally feel how they moved up my spine into behind my ears and this is where they are sitting and moving around and possibly multiplying. I have started doing all sorts of test and am waiting on blood, urine/hormone, omega3 etc. A functional practitioner wants to see it from a holistic point I am working with. But he also wants me to take ozonated oregano oil for the Blasto. After reading all your posts I am more inclined to kill them right out hard. But here come my fears, I have never taken any antibiotics in my life, never any drugs - nothing. I am fearful that my heart is going to stop due to parasite being killed in my heart. I want to understand how this works. I have gone through ICU's protocol and am inclined to put myself and my husband on it. Bu I am scared - not only of the side effects of the drugs but also the possible die off effects from the worms. I have never been tested for a tapeworm so can't say for sure what is happening. How can I get tested for tapeworms in the heart and brain? I would appreciate your thoughts and knowledge on my healing path. Thank you.
