anxiety
"I started taking atenolol (25 mg) right after Thanksgiving for heart palpitations. When I saw the Dr he said I had sinus tachycardia, but I also have severe panic disorder. I can tell a big difference. I will have a palpitation every now and then but my resting heart rate is down. I haven't noticed that my anxiety is down so I still take my .25 xanax when I need it. I also haven't noticed any side effects other than a little dizziness and a little chest tightness. Its kind of been a life saver because my palpitations would put me in a panic attack. I would recommend this to anyone that would benefit from it."
