Dizziness caused by cardiovascular disease should be treated for the cause. 1. Hypertension: When the patient’s blood pressure suddenly increases and the cerebral blood vessels dilate, the patient will have dizziness, headache and other symptoms. Nifedipine controlled-release tablets, fosinopril, timosartan and other antihypertensive drugs can be given to treat dizziness, which can be gradually relieved after controlling blood pressure. 2. Cardiac insufficiency: it can lead to insufficient blood supply to the brain, and patients may have dizziness symptoms. Diuretics such as furosemide and torasemide can be given to reduce the volume load of the heart; drugs such as deacetyl furfuryl glycoside can strengthen myocardial contraction and slow down the heart rate; fosinopril and enalapril can improve the heart function. 3. Arrhythmia: When tachyarrhythmia occurs, the patient’s heart rate increases and the ejection volume decreases, resulting in insufficient blood supply to the brain and dizziness and other symptoms. When tachyarrhythmia occurs, amiodarone, metoprolol and other drugs can be used to adjust the heart rate. When bradyarrhythmia occurs, due to the slowing down of the heart rate, the heart’s ejection volume is reduced and the blood supply is insufficient, which can also cause dizziness or fainting and other symptoms, and can be treated with drugs such as atropine and isoproterenol, and if necessary, the installation of a pacemaker is required for treatment. When dizziness is caused by cardiovascular disease, you should consult a doctor in time, after clarifying the specific cause of the disease, follow the doctor’s instructions to use medication, and do not blindly abuse drugs on your own. Pay attention to rest during dizziness to avoid accidents such as falls.
