Brief Answer:
Can be a side effect of metoprolol

Detailed Answer:
Dear Sir,

Metoprolol slows down heart rate and sometimes patients, who takes metoprolol, can develop bradycardia as a side effect.
Also heart rate drops when during the sleep and raises when a person wakes up.
If you have heart rate of 65 now it is good. But I would advise you to see your doctor and have a holter monitoring performed. It is a test during which you 24 hour ECG is recorded, so your doctor can observe if you have slow heart rates during the night.
Until the test I would advise you to monitor your heart rate, if you have slow heart rates and you feel tired or dizzy there will be a need to reduce the dose of metoprolol.

Hope I could help you

Wishing you good health

I have uneven heart beat that is lasts for hours and days on end. The heart beats normally for a few beats have a strong beat, halt for a longer period then resumes for a few beats then the same cycle repeats. I do not experience dizziness with this. I take Fosinopril ( 20 mg) and Amlopidine ( 5 mg). I have had this often on for a few years, then they seem to subside substantially once I was put on fosinpril. They used to increase substantially if I consume alcohol. In this case I wake up in the middle of the night with these symptoms and las for a few hours. I have stopped drinking completely for the last few years. But now I have them every day for hours. , Two weeks ago my doctor installed for me an on demand, two lead pacemaker for bradycardia.

My son received a king hit 3 Dec 2010 he lost consciousness for 10 minutes. Pulse rate 34. He also had post concussion syndrome and a sprained neck. He was admitted to cardiology. We were advised he has bradycardia and he was released. No treatment was provided I was told he would be fine he is a young fit boy.
He received physio 23 Dec 2010 he had a pulse rate of 57. We visited a different Dr 23 Mar 2011 for another issue; I mentioned to the Dr about the incident and he took his pulse which was 40 then he had a ECG which showed his pulse rate at 35. We went to hospital and we were released again diagnosis sinus bradycardia. We have an appointment to see a private cardiologist in five days. Even though my son is fit and swims I would not say he would be like an olympic athlete. Could the sinus bradycardia be a result from the king hit? CT head scan in Dec showed there was no blood the CT scan was taken the day of the incident. Could there still be a chance there could be?

Hey, I was diagnosed with an eating disorder and the effects were secondary amenorrhea and bradycardia. My resting rate rate then was 45 and they said it could be reversed but I was wondering if it was possible to reverse it in a week? I ve been following their orders of eating more for about 5 days now and my resting heart rate is between 70-80 every time I check it.
