Bradycardia, PVC's and Migraine

I am a 44 year old female, with history of Daily Migraines for 8 years have seen Neurologist with frequent preventative medication trials with no success.  I  also have hypothyroidism and take 137 mcg of Sythroid daily.  I have a history of PVC's and bradycardia.  The PVC's have gotten progressively more frequent and I am currently on a halter monitor for 3 weeks.  Whenever I am at the doctor or have had a procedure done that has had me on a monitor they always comment on the bradycardia and the amount of PVC's that I have.  I have notice recently that when I have a headache and then have a run or several runs of PVC' that the headaches intensify to the point of a 9-10 on a scale of 10.  Can the PVC's or the bradycardia be the cause of the daily headaches?  We have done CAT scans and MRI's and EEG and the Nuerologist has not found anything that can be causing daily headaches.  We have tried Beta Blockers in the past for the headaches but we find they cause a drop in my blood pressure and cause dizziness which we attribute to the decrease in HR.  Are there any links between bradycardia, PVC' and Migraines

Some people can feel dizzy or slightly lightheaded with PVC's or bradycardia but to my knowledge there is no link between these fairly common events and migraine headaches.
