If increased heart rate and insomnia are not due to cardiovascular disease, pulmonary disease, or thyroid disease, consider a diagnosis of cardiovascular neurosis.

Patients with cardiovascular neurosis often present with numerous and variable complaints, lacking an intrinsic connection between symptoms. Common symptoms include palpitations, a heightened sense of heartbeat, chest tightness, labored breathing, a frequent feeling of insufficient air requiring opening windows or needing oxygen, accompanied by insomnia, vivid dreams, anxiety, loss of appetite, dizziness, tinnitus, sweating, cold hands and feet, and trembling hands.

Treatment primarily involves psychotherapy, with medication as a secondary approach. Patients are encouraged to adjust their attitudes, organize their schedules properly, and engage in cultural, tourism, and sports activities. In cases of severe insomnia, the cautious use of drugs like midazolam or zopiclone may be considered.

(The use of medications should be under the guidance of a physician)
