Reflex bradycardia
Reflex Bradycardia is a medical condition characterized by a decrease in heart rate that is initiated by the body's natural reflexes. This condition is often a response to certain stimuli, such as high blood pressure or certain medications.
Causes[edit | edit source]
Reflex bradycardia can be caused by a variety of factors. These include:
- High blood pressure: When blood pressure is too high, the body may respond by slowing the heart rate to reduce the pressure.
- Certain medications: Some drugs, particularly those used to treat high blood pressure and heart conditions, can cause reflex bradycardia.
- Vagal stimulation: The vagus nerve, which helps control the heart rate, can be stimulated by activities such as vomiting, coughing, or bearing down during a bowel movement. This can cause the heart rate to slow.
Symptoms[edit | edit source]
The symptoms of reflex bradycardia can vary depending on the underlying cause and the individual's overall health. However, common symptoms can include:
