Your issues are unusual and may be above the skill set of many GPs... That's not to say you CAN'T get good advise there, but, be careful.

BTW, most often, a rapid heart rate is usually triggered by a med (such as a Calcium Channel blocker) or by low blood pressure: A systolic of 95 will increase your heart rate. It MAY be that your base issue is low blood pressure. But, then, you have to ask: "What is causing the low blood pressure?"

... And then you have to ask: "Is any of this causing a problem that needs to be addressed?" Or, are they simply just unusual numbers?

Low Blood pressure can cause, dizzyness (especially when standing) and resulting falls. Also, your organs may not be getting the perfusion that they need... On the other hand, maybe not...
... It's above my skill set too!
