I was diagnosed with Graves disease
a few weeks ago and
was put on 25 mg of Atenolol. This worked well for palpitations and racing pulse for about 2 weeks, and then the symptoms returned, so my dr. increased my dosage to 50 mg daily (once in morning, once at bedtime). My pulse rate has gone from 103-110 down to 73-80, so in that respect it is working. However, my heart is still pounding, and I am still having periodic chest pain, along with some palpitations.
