Bradycardia is a medical condition characterized by a slower than normal heart rate, typically defined as fewer than 60 beats per minute. It can occur in healthy individuals, especially athletes, but may also indicate underlying health issues such as heart disease, hypothyroidism, or electrolyte imbalances. Symptoms can include fatigue, dizziness, and fainting. In some cases, bradycardia may not require treatment, especially if there are no symptoms. However, if it leads to significant health problems, doctors may recommend interventions such as medications or a pacemaker to help regulate the heart's rhythm. Regular monitoring is essential for those affected.
