Bradycardia is a situation where a person has an abnormally low resting heart rate. In the case of adults, it is defined as being less than 60 beats per minute. In many patients, however, no symptoms are noticed until this number drops to less than 50 bpm. However, neither number is fixed in terms of determining whether or not the situation is problematic. For instance, many young people, especially athletes, have a resting heart rate that is usually low. As long as no adverse symptoms are noted along with it, this is generally not considered to be a problem. On the other hand, some people might have a number which is relatively low given their current health status, and this may be problematic despite the fact that it is still above 60.
There is a number of different possible symptoms associated with bradycardia. A sense of weakness may be present. The person might experience dizziness. Heart palpitations and/or painful sensations in the chest may occur. Shortness of breath, known as dyspnea, can also be a symptom. There are different classifications of this condition, and a patient may have different symptoms in any particular type, as well as in a specific case.
In general, there are two main types of causes of bradycardia: those that are cardiac in nature, and those that are not. Chronic ischemic heart disease is one of the possible cardiac-related causes. Some possibilities for the other type include thyroid problems and other metabolic reasons, neurological issues, etc.
A medical professional is involved in the diagnosis of bradycardia. It may be possible for a non-professional to note whether the heart rate is below 60, but for qualified diagnostic work please look for assistance from a professional. A separate diagnosis might also be given for the underlying reason behind the low heart rate.
Cases of bradycardia are not always treated the same way. Please get input from a qualified individual rather than attempting to choose a treatment based on anything you read on this page. Mainly, the preferred treatment to be used is based on whether or not the patient is stable. Those who are in unstable condition may be given more in the way of emergency treatment. The underlying cause may also affect the type of treatments that are administered to the patient.
