Bradycardia is a medical term used to describe an abnormally slow heart rate. It is characterized by a heart rate lower than the normal range for a person's age and overall health condition. In adults, bradycardia is typically defined as a heart rate below 60 beats per minute.
Bradycardia can occur due to various factors such as aging, certain medical conditions, medications, or problems with the heart's electrical signaling system. Athletes and individuals who engage in regular exercise may also experience a lower heart rate due to their increased cardiovascular fitness.
While some individuals with bradycardia may not experience any symptoms, others may develop signs such as fatigue, dizziness, fainting, shortness of breath, or chest pain. In severe cases, bradycardia can lead to complications such as low blood pressure, heart failure, or even cardiac arrest.
The diagnosis of bradycardia typically involves measuring an individual's heart rate through an electrocardiogram (ECG). Treatment for bradycardia depends on the underlying cause and severity of symptoms. In some cases, lifestyle modifications, such as reducing the use of certain medications or avoiding triggers, may be sufficient. However, more serious cases may require medical intervention, including pacemaker implantation to regulate the heart's rhythm.
In summary, bradycardia refers to an unusually slow heart rate that can be caused by various factors. It is essential for individuals experiencing bradycardia symptoms to seek medical evaluation for proper diagnosis and treatment.
