Beta-blockers block the action of the sympathetic nervous system of the heart, thus reducing stress on the heart. Doctors may prescribe beta-blockers for patients with tachycardia (rapid heart rates). They help patients with angina by lowering the amount of oxygen the heart muscles require. They also help patients with high blood pressure and migraines.

Thank you for your reply. I now have a GTN spray to use when I exercise and it stops any tightness/pain in chest and feel I have more breath and am able to do my exercise so much better. I have not been put on the Beta blocker just yet, Im to get further blood tests and referred back to cardiology if things dont improve.Im glad the GTN spray is allowing me to continue to exercise and stops my pain but worry that this means I have the start of narrowing arteries.
Wondering now if this is linked to autonomic dysreflexia. Ive also got MS , mainly spinal cord lesions and now wondering if they are causing the problems.
