question: I am being treated for ventricular arrythmias with documented episode of v tach (only 6 beats) during a loop monitor for 2 weeks which i wore in the daytime only; my loop monitor also showed so t wave inversions with episodes of frequent pvc s and st segment changes. my stress test was negative. started on monocor 5 mg once/day and increased to 7.5 mg once a day as i was having frequent chest pain and 85 pvc s / hour. i was told that the chest discomfort that i am experiencing and the pvc s are related to a mitral valve prolapse with scant regurgitation. Should i be concerned? I work part time but am totally exausted.
