I am wondering if you are on any medications for your heart or BP? You may be having runs of SVT and your cardiologist will perhaps order a holter monitor which is an event monitor that your will wear at home for usually a 24 hour period to try to catch your runs of fast heart rates. A heart rate of 200 could cause your BP to drop down.
Do write all your concerns down and discuss each one with your Dr. Let us know how you make out as we are here to support you.
