Bradycardia is a condition where the heart beats fewer than 60 times per minute, which is slower than the typical rate for adults. However, a resting heart rate between 40 and 60 beats per minute is quite common during sleep and in some people, particularly healthy young adults and trained athletes. Bradycardia can be a serious problem if the heart rate is very slow and the heart cant pump enough oxygen-rich blood to the body. Symptoms of bradycardia include fatigue, dizziness, lightheadedness, confusion, fainting, shortness of breath, chest pain, and tiring easily during exercise. If the heart rate is dangerously low, it can cause insufficient blood flow to the brain and other organs, which can lead to complications such as heart failure, frequent fainting, and cardiac arrest.
It is important to note that bradycardia can have a variety of causes, including heart problems, medicines, electrolyte imbalances, and sleep apnea. Treatment depends on the underlying cause of the condition. Borderline or occasional bradycardia may not require treatment, but severe or prolonged bradycardia can be treated with medication or an implanted pacemaker to help the heart maintain an appropriate rate. If you are concerned about a slow heart rate, it is important to see your healthcare provider for a prompt and accurate diagnosis and appropriate care.
