Cardiac neurosis is a group of clinical syndromes in which symptoms related to cardiovascular disease are the main manifestation, but no organic lesions are found after examination. This condition is most often seen in menopausal women or in people who are chronically stressed, anxious, tired, and stay up late. There are no specific tests that can confirm the diagnosis of cardiac neurosis; it is a diagnosis of exclusion. Patients with cardiac neurosis can often present with abnormalities such as chest tightness, palpitations, dyspnea, anxiety, insomnia, lack of appetite, dizziness, headache, tinnitus, chills in the hands and feet, tremors in the hands, frequent urination, constipation, increased frequency of bowel movements, stomach discomfort, and numbness in the limbs. And during the onset of symptoms can manifest as symptoms of discomfort in multiple organs and parts of the body, but after detailed examination, no obvious abnormalities are found. The patient’s so-called dyspnea is often relieved after opening a window for ventilation, or after deep inhalation. Patients with severe cardiac neurosis may also experience a sense of near-death and self-conscious cardiac arrest. For patients with cardiac neurosis, psychotherapy must be the primary treatment, supplemented by medication. It is recommended that patients should work and rest regularly, avoid straining and staying up late, relax more, and listen patiently to the patient’s medical history to find out the patient’s anxiety factors to relieve the patient’s doubts, and it is also recommended that patients can take some mood-improving and anti-anxiety drugs. Representative drugs are fluoxetine, sertraline, etc. Although these drugs are relatively safe, but the onset of action is relatively slow, generally speaking, after two weeks of taking gradually began to take effect.
