Panic attacks with no trigger
There might be this common misconception that panic attacks must always be triggered, but there is such thing as panic attacks for which there is no obvious cue or trigger at the time of occurrence— that is, the attack appears to occur from out of the blue.
This happens often in an Anxiety disorder called Panic disorder. Which refers to recurrent and unexpected panic attacks.
The determination of whether panic attacks are expected or unexpected is made by the clinician, who makes this judgment based on a combination of careful questioning as to the sequence of events preceding or leading up to the attack and the individuals own judgment of whether or not the attack seemed to occur for no apparent reason.

You are correct. Panic attacks can be expected or unexpected, but there are more criteria to qualify for Panic disorder. To be a little more specific.. A diagnosis of Panic disorder is based on the criteria that the unexpected panic attacks are marked by the continuous fear of having attacks or future attacks and/or you worry about the implications of the attack and you change your behavior to avoid having them in addition to experiencing this for at least a month.
