I am a 18 yr old guy who has long QT, atrial fribultion, and ventricular tachacardia, I am also on 120mg of propranolol 3 times a day, 250mg of mexiletine 3 times a day, 120mg of deltiazem 3 times a day, 16mg of atacand once a day and, 3.75mg of warfarin or coumadin. I was wondering if smoking pedicularis densiflora would cause anything to mess with my medicines/ heart . Any help would be greatly appreciated.
