Hypertension causes bradycardia through a negative feedback mechanism. Hypertension causes the increased systolic blood pressure to stretch the baro receptors within the neck which then sends a message to the brain that tells the SA node in the heart to reduce the rate and force of contraction.
However, it is also important to acknowledge that hypertension alone is not the only cause of bradycardia.
What Causes Bradycardia?
The following are common causes of bradycardia:
2. Electrolyte imbalances.
3. Cerebral events/stroke.
4. Sick Sinus Syndrome.
5. Disorders of the SA node.
6. Congenital Heart Defects.
7. Underactive thyroid gland.
9. Digoxin overdose.
10. Myocardial infarction/ischeamia.
