Description: Bradycardia is a slower than normal heart rhythm, typically below 60 beats per minute. This phenomenon can be a normal physiological response in healthy individuals, such as trained athletes, where a more efficient heart can pump blood adequately with fewer beats. However, in other cases, bradycardia may be a sign of underlying problems in the heart’s electrical system, potentially leading to decreased blood flow and symptoms such as fatigue, dizziness, or fainting. Bradycardia can be classified into two types: sinus bradycardia, resulting from a decrease in the frequency of the sinus node, and heart block, which occurs when there is a disruption in the heart’s electrical conduction system. Identifying and treating bradycardia is crucial, as severe cases may require the implantation of a pacemaker to regulate the heart rhythm. Bradycardia is a topic of interest in cardiology, as its diagnosis and management can significantly impact the patient’s quality of life and long-term prognosis.
