Central bradycardia is a medical condition where the heart rate slows down due to a malfunction in the central nervous system. This term is spelled as /ˈsɛntrəl brædɪˈkɑrdiə/ in the International Phonetic Alphabet (IPA). The first syllable "cen" is pronounced as "sen", the second syllable "tral" is pronounced as "trəl", and "brady" is pronounced as "brædi". The final syllables "cardia" are pronounced as "ˈkɑrdiə". This spelling guide helps both medical professionals and patients to communicate efficiently and accurately about the condition.
Central bradycardia refers to a medical condition characterized by an abnormally slow heart rate that originates from a dysfunction in the central nervous system. The central nervous system, which includes the brain and spinal cord, plays a crucial role in regulating heart rate. In central bradycardia, the electrical signals that control the heart rate are disrupted, leading to a slower than normal heartbeat.
The normal resting heart rate for adults is typically between 60 and 100 beats per minute. However, in central bradycardia, the heart rate may drop below 60 beats per minute or even lower, depending on the severity of the condition. This slow heart rate can result in a variety of symptoms such as fatigue, dizziness, fainting, shortness of breath, and chest discomfort. In severe cases, it may even lead to loss of consciousness or cardiac arrest.
Central bradycardia can be caused by various factors including underlying medical conditions like hypothyroidism, electrolyte imbalances, medication side effects, damage to the central nervous system, or cardiac disorders affecting the heart's pacemaker cells. It can also result from age-related degeneration, certain genetic disorders, or autoimmune diseases affecting the nervous system.
Treatment for central bradycardia depends on the underlying cause and severity of symptoms. In some cases, medication may be prescribed to help regulate the heart rate. In others, a pacemaker may be implanted to electrically stimulate the heart and maintain a normal heart rate. It is important for individuals experiencing symptoms of central bradycardia to seek medical attention promptly for proper diagnosis and appropriate management.

The word "central" in the term "central bradycardia" refers to the location or source of the condition. In the context of medical terminology, "central" typically indicates an origin within the central nervous system.
The term "bradycardia" is derived from Greek roots. "Brady" means slow or low, and "cardia" refers to the heart. Therefore, "bradycardia" describes a condition characterized by an abnormally slow heart rate.
So, "central bradycardia" refers to a type of bradycardia that originates from a central nervous system dysfunction, where the brain fails to adequately regulate the heart rate.
