Cayenne and Heart Rhythym

A few months ago I did the Humaworm Cleanse. About that time I started getting irregular heart rythyms. This past week I went to my doctor and showed him the ingredient list. Simple question. Anything on the list which might trigger an irregular heartbeat? The ONLY thng he pointed out was CAYENNE. I was very surprised by that.

Question to Cayenne users. ANYONE ever experience irregular hear beats during the cleanse or just using Caynne, in general?
