Can someone with asthma, tachycardia and panic disorder take low dose beta blockers

Can someone who has asthma, panic disorder and tachycardia take a low dose beta blocker since i heard beta blockers are the best for tachycardia?  Currently, i am taking 2 mg. zoloft along with 1 mg. clonazepam up to 3 times a day as prescribed by my dr.

These used to keep my heart rate down to below 100, but now they are not working as good.  i get excessive heartbeats up to 130, but at least these medicines are keeping me more calmer so that i do not get panic disorder and make my heartrate go up any higher.

Thank you.
