Approximately one sixth of the patients treated at Emergency Heart Care units is having a panic attack rather than heartproblems. Indeed a panic attack could have some of the same symptoms as a heart attack (for example: chestpain, heart palpitations, being short of breath).
In Holland, this was a reason for a psychiatrist to join the team of cardiologists, to screen every patient showing up at the Emergency Heart Care. This way, patients actually suffering from a panic attack could get the right treatment faster.
