Please can anyone explain this term?
A few months ago after an ultrasound scan I was told I had inappropriate sinus tachycardia. (Heartbeat usually around 108-110 resting). I also have low blood pressure. Yesterday I saw a cardiologist who didn’t feel there was any need for treatment stating I just have a reactive heart rate. Please can anyone shed any light on this?
