Panic attacks are also known as acute anxiety attacks. The patient experiences a sudden onset of intense discomfort, including tightness in the chest, a feeling of being out of breath, palpitations, sweating, stomach discomfort, trembling, numbness in the hands and feet, a sense of dying, going crazy, or a sense of being out of control, for about a quarter of an hour each time the attack occurs. The attacks may have no apparent cause or no particular situation. Others have attacks in specific situations such as crowds, stores, and public vehicles. The latter is called agoraphobia with panic attacks. Typically, the patient is carrying out daily activities, such as reading a book, eating a meal, taking a walk, going to a meeting, or doing housework, when he or she suddenly develops a strong sense of fear, as if he or she is about to die. This nervousness is unbearable for the patient. At the same time, the patient feels palpitations, as if the heart is going to jump out; chest tightness, a feeling of pressure in the chest area; or breathing difficulties, throat blockage, as if they can not breathe, and are about to die of asphyxiation. As a result, the patient will scream, call for help or run outside, hold his head, and in some cases, hyperventilate, dizziness, facial flushing, excessive sweating, unsteady gait, tremor, numbness of the hands and feet, gastrointestinal discomfort and other vegetative symptoms, as well as locomotor restlessness. This kind of attack, usually 5-20 minutes, a shorter period of time, can be relieved by themselves, after the relief of the patient’s self-consciousness of all normal, but soon there can be a sudden relapse. Most of the patients in the intervals after the recurrence of panic attacks, often worried about the reoccurrence of the attack, and therefore anxious, may also appear some symptoms of hyperactivity of the vegetative nervous system. Panic attacks are not heart disease! Medications are effective for panic disorder.
