Symptoms of slow heartbeat and high blood pressure require clarification of whether hypertensive disease is combined with organic heart disease, which leads to phenomena such as atrioventricular block. Patients with hypertension often have increased sympathetic excitability, and a slow heartbeat often indicates abnormalities in the cardiac conduction system, commonly associated with various types of arrhythmias. In patients with sinus node dysfunction, it can occur in patients with myocardial ischemia, surgical trauma in patients with myocardial infarction, and neuromuscular disease, among others. In addition, slow heartbeat can occur in other diseases such as hypothyroidism, intracranial disease, obstructive sleep apnea syndrome, and other causes of bradycardia, often coexisting with high blood pressure. In patients with high blood pressure, the use of beta-blockers can lead to a decrease in blood pressure and a slowing of the heart rate.
