Suggest Remedy For Spasms In Chest Followed By Warm Blood Rush

Hi. Since last week I ve been feeling spasms in my chest followed by a warm rush of blood sensation. I actually went to emergency because of this and was admitted to hospital for a few days with tachycardia. They reduced my heart rate with beta blockers but never addressed theses spasm sensations which are more disturbing to me than the fast pulse.

Thanks for your question on HCM.
I can understand your situation and problem.
Betablockers are known to cause bronchospasm.
Beta receptors in bronchi are needed for bronchodilation, Especially beta 2 receptor.
So whenever nonselective beta blockers are given, they will block the action of beta 2 mediated bronchodilation and cause bronchospasm.
So better to start cardio selective betablocker (beta 1 selective). It Is having only beta 1 action and no action on beta 2 receptor in bronchi, So no bronchospasm. Beta 1 receptors are present in heart so beta 1 antagonist ( cardio selective beta blocker) will have effect only on heart.
So consult your cardiologist and change to cardio selective beta blocker.
