Thanks for posting your query.
Yes, the symptoms that you are experiencing can all be attributed to the HIV infection in you. HIV infection commonly causes coronary heart disease
, dilated cardiomyopathy
, and in advanced stages pericardial effusions. These may be causing the high heart rate

It is also common to suffer from repeated sinus infections and headaches
Hope you are managed appropriately.
