High blood pressure can cause some people to have panic attacks, which are related to sympathetic excitation, cardiac hypertrophy, myocardial ischemia, etc. It is recommended to consult a doctor for a comprehensive examination. 1. Sympathetic nerve excitation. When the blood pressure rises, it will stimulate the sympathetic nerves of the body to become excited, thus affecting the heart and causing the heart rate to increase, and then palpitations and panic attacks will occur. 2. Myocardial hypertrophy. If high blood pressure exists for a long time, it will make the heart need more contraction force when pumping blood, which can lead to myocardial hypertrophy in the long term, and then the persistent high blood pressure will lead to increased heart rate, which will lead to panic and other discomforts. 3. Myocardial ischemia. If the coronary arteries of the heart have plaque, stenosis and other lesions, the blood supply to the myocardium is insufficient when the blood pressure rises or increases the burden on the heart, resulting in increased heart rate. If you have repeated panic attacks and poor blood pressure control, it is recommended that you seek medical attention as soon as possible to avoid delaying your condition.
