Answer

Routine blood studies may be needed to help rule out noncardiac conditions triggering tachycardia. These may include the following:

  • Complete blood count (CBC)
  • Chemistry panel (blood urea nitrogen [BUN] and creatinine to assess renal status)
  • Liver function tests
  • Thyroid panel
