Which disorder is characterized by extreme panic attacks and a racing heartbeat?

Panic disorder is characterized specifically by the occurrence of recurrent and unexpected panic attacks, which are sudden periods of intense fear or discomfort that peak within minutes. During these attacks, individuals may experience symptoms such as a racing heartbeat, shortness of breath, trembling, sweating, and feelings of impending doom. The hallmark of panic disorder is the intensity and frequency of these panic attacks, which can lead to significant anxiety about experiencing future attacks. This distinction sets panic disorder apart from other mental health conditions like bipolar disorder, major depressive disorder, and phobias, which have different symptom profiles and criteria for diagnosis.
