bradycardia/brady·car·dia/ (-kahr´de-ah) slowness of the heartbeat, as evidenced by slowing of the pulse rate to less than 60.bradycar´diac
bradycardiaSlow heart rate, commonly defined as a rate of < 60 bpm or a rate which is too slow to be physiologically appropriate for the person and/or activity (generally recognised as < 45 beats/minute in men, < 50 beats/minute in women). A notable exception is aerobic athletes, whose resting heart rates are significantly lower than those of non-athletes.
Symptoms may be specific (syncope) or nonspecific (dizziness, fatigue, weakness, heart failure).
Beta blockers (pindolol), pacemaker.

bradycardiaA slow heart rate. In the healthy this often indicates a high degree of fitness, but bradycardia can be a sign of heart disease, such as heart block, an effects of digitalis or beta-blocker overdosage or the result of thyroid underaction (MYXOEDEMA).
bradycardiaan abnormal reduction in heart rate.
bradycardiaslow heart rate, defined as 60 beats per minute or less; known as sinus bradycardia when it arises from the normal pacemaker in the heart (the sinoatrial (SA) node), e.g. the slow resting heart rate in trained athletes, when vagal tone is increased. Pathological causes include the action of some drugs, or hormonal or electrolyte abnormalities; a fixed slow rate can arise from an abnormal focus, when the spread of excitation from the SA node is prevented by 'heart block'.

Patient discussion about bradycardia
Q. What is considered a slow heartbeat? I am a 30 year old woman and I went for a routine checkup at my Doctor's. He checked my pulse and it was 52 beats per minute. Is this considered slow? All my family members have a faster beat of 65- 90 beats per minute. If it is slow, is it bad?
Fainting or near fainting
However, some people with slow heartbeat don't have any symptoms at all. Regular exercise can also result in a slow heartbeat. This happens because the exercise has actually strengthened the heart to the point where it can beat less often and still perform its job effectively. I am not a doctor, but it seems to me that in this case the slow heartbeat is not a cause for concern. If it troubles you, consult your doctor and see what he/she thinks about it.
Q. SVT and AF, Hearts that go fast to slow or any others probs with the beats of any kind and Ablation of hearts I have had Ablation done once and I am still having passing out spells and still on 50mg toprol 2 times a day till two days ago, now I am on 150 to 200 aday again.
