If a patient feels fast heartbeat and panic from time to time recently, it is considered possible that the patient has anemia, or the patient has heart failure, hyperthyroidism, or insufficient blood supply to the heart muscle, all of which may cause the patient to feel panic. If you want to make a clear diagnosis, it is recommended that the patient can have an electrocardiogram. In addition, further measurements of heart rate and blood pressure and a cardiac ultrasound should be done to help clarify the diagnosis. In some patients, it may be due to cardiac neurosis or disorders in the regulation of plant nerves that cause the discomfort of heartbeat. It is recommended that patients should first exclude organic lesions, and if no cause is found, psychosomatic factors should be highly considered. If it is caused by anemia or ionic disorders, or hyperthyroidism, it is necessary to correct the anemia, ionic disorders, and hyperthyroidism in order to better improve the current discomfort.
