If the patient is experiencing a rapid heartbeat and dizziness, it is recommended that the heart rate and blood pressure be measured to see if the dizziness and rapid heartbeat are caused by high blood pressure. In addition, it is recommended that the patient should have an electrocardiogram if it is convenient for him or her, so that he or she can evaluate what type of tachycardia the rapid heartbeat is and better choose the relevant medication for treatment. If the patient is indeed hypertensive and has a fast heartbeat, it is recommended that the patient take antihypertensive medication and combine it with bisoprolol or metoprolol, which will not only lower the blood pressure but also help slow down the heart rate. If the patient has a previous history of coronary heart disease, it is recommended that the patient also take sublingual heart pills or compound salvia drops. Because sometimes the rapid heartbeat may also be caused by myocardial ischemia, if the patient does not see any relief after taking the medication, he should go to the emergency department for further examination and treatment.
