Cardiac neurosis can cause frequent premature contractions because many psychiatric factors can cause premature contractions, such as chronic mental stress or plant nerve dysfunction. Patients with cardiac neurosis causing premature contractions should pay attention to emotional regulation, and if necessary, they can visit the psychology department to improve their mental stress. Patients are advised to take regular rest and exercise and outdoor sports to improve their bad habits. The patient can choose nerve-nourishing drugs, such as glutathione, and apply drugs for premature beats, such as atenolol or Chinese medicines, such as heart-stabilizing granules and ginseng heart capsule.
