Feeling that the heart is beating out of the chest is usually related to physiological factors, arrhythmia, hypertensive heart disease, hyperthyroidism, etc. General treatment and medication should be taken to alleviate the symptoms in conjunction with the cause of the disease. 1. Physiological factors: panic, shortness of breath, rapid heartbeat and other symptoms may appear suddenly after emotional excitement, irritability, nervousness, fear and strenuous exercise. These symptoms are normal and do not require special treatment, and will gradually decrease after they are removed from the causative factors. 2. Arrhythmia: For example, common tachyarrhythmia, especially supraventricular tachycardia, is characterized by a rapid heartbeat, which is sudden and stops suddenly, without any cause, accompanied by dizziness, palpitations and other discomforts. It can be treated with medicines such as metoprolol tartrate and radiofrequency ablation. 3. Hypertensive heart disease: It is caused by the aggravation of hypertension, which leads to the increase of heart load. Blood pressure should be monitored regularly and oral antihypertensive drugs such as nifedipine extended-release tablets and enalapril tablets should be taken reasonably. 4. Hyperthyroidism: When the thyroid hormone level increases and causes hyperfunction, it may lead to increased heart rate. Thyroid hormone should be controlled as soon as possible. Oral propylthiouracil can be taken clinically, and oral propranolol can be taken if combined with cardiac arrhythmia. If you feel that your heart is about to beat out of your chest, such as chest tightness and chest pain, tightness, etc., it is recommended that you consult a doctor promptly and follow the doctor’s instructions.
