How long it takes for cardiac neurosis to heal on its own depends on the severity of the patient’s condition and individual factors, and cannot be generalized. Cardiac neurosis is not an organic heart disease, but rather a phenomenon of panic, palpitations and chest tightness caused by anxiety, stress, insomnia, exertion or psychological suggestion. In mild cases of cardiac neurosis, the symptoms can be significantly reduced by relaxation, regular rest and psychological suggestion, and can be cured by itself in about a month. In the case of severe cardiac neurosis, the patient cannot get rid of the depressed life on his own, so he usually cannot heal himself and needs to actively cooperate with the doctor for treatment. In short, patients with cardiac neurosis are recommended to go to the cardiology department of a regular hospital in a timely manner to have their cause clarified and then treated actively. In daily life, you should adjust your mind, arrange your work and rest time, and do recreational activities appropriately.
