Is it safe to perform Carotid Mage on one's self?

I'm a 28 y/o female and I have been suffering from Sinus Tachycardia and episodes of SVT for the past 5 years. I've been put on various beta blockers throughout those 5 yrs. I was looking for alternative therapies to help slow my heart down without all the side effects that come with it. I read extensively about Carotid Sinus Mage and how it helps slow down the heart rate. My question is, is it safe for me to do this on myself if my heart rate gotten too high?
