Can high blood pressure caused by stress result in a constant sinus tachycardia? Or is it the other way round? In April I was diagnosed with Sinus Tachycardia with a very high blood pressure. I am on beta blockers now but it doesn t always work, my blood pressure can fluctuate but my heart rate can still race. I also get anxiety alongside some Chronic Fatigue like symptoms (tingling, pins and needles, visual probs, muscle pain etc) Also, can constant anxiety cause chronic sinus tachycardia? (I ve been tested blood wise and they only conclusion the doctor has is either chronic faituge syndrome or anxiety or both)
