I have episodes of SVT which gets on my last nerve. I have started on Friday the HCG drops that I got from GNC to start weight loss . I had a episode of SVT on Sat and again this morning (Sun). This is rare for me could it be the drops which I showed my cardiologist that I was going to take. ( I had a appt with him on Thursday) He told me from what he could tell in the ingreditents it shouldn t interfere. Just wondering why all of a sudden the back to back episodes. Could it be stress? I take Metropolol and Verapamil 120 the doctor told me to double up in the morning on the verapamil. I did that on Sat and shortly after taking it the SVT episode and paps went nuts. This morning I hadn t taken any med s yet and sure enough I felt the paps, followed by svt. I took the Metropolol and 1 verapamil. After about a 1/2 hour I took another verapamil and my heart rate dropped to normal.
