Heart alarm generally refers to the symptomatic manifestation of intense heartbeat and panic, which belongs to the category of palpitation and dizziness in Chinese medicine. Heart alarm is a subjective feeling of its own, mainly due to the emotion of panic, shock, excitement and other reasons, resulting in the appearance of panic and a feeling of panic. If the patient is often prone to heart fright, it is considered that it may be related to heart problems, such as organic heart disease, including arrhythmia, irregular heartbeat, chronic arrhythmia, etc., which may trigger symptoms such as heart fright. It may also be caused by a deficiency of the heart, gallbladder and qi. If the symptoms of heart alarm occur frequently, it is recommended to go to the regular hospital in time, improve the relevant examination, and standardize the treatment under the guidance of the doctor.
