Medical workers working in the front line of the clinic, especially in the emergency department of general hospitals, often receive emergency calls of “heart attack” or patients with the main complaint of “heart thumping hard”. After the doctor performs emergency treatment and preliminary examination, it is found that there is no abnormality in ECG, blood pressure, blood biochemistry and other indicators, and the patient’s acute symptoms also disappear. For experienced doctors, they will recommend the patient to go to the psychiatry department for systematic examination and treatment. In fact, this is a very typical manifestation of panic attacks in anxiety disorders. Patients often experience a sudden panic attack with a sense of near death or loss of control and severe autonomic dysfunction. The patient may feel as if death is imminent, run, scream, call for help, or faint. The survey found that 89% of panic patients complained of tachycardia, irregular heartbeat, and chest pain, and 25% of patients were first seen in cardiovascular or cardiology departments as a result. Patients’ seizures generally lasted 5-20 minutes and rarely lasted more than an hour. Consciousness is always clear during the attack, but alertness is heightened. In today’s neuroscience community, this perception of abnormal heartbeat is called abnormal heartbeat perception.
