What is the most cause of EKG findings in this patient?

  • A) MI – can rarely cause pleuritic pain.  Rarely causes tachycardia
  • B) pericarditis – can cause central pleuritic CP but not typically these ECG changes

  • D) GERD – shouldn’t cause ECG changes but can cause T wave inversion.  A diagnosis of exclusion
