Overview

Many cases of premature atrial contraction have no definite cause, it may be the result of various other problems. A more extensive work-up is only indicated when PACs present with severe symptoms and complications.

Laboratory Findings

• Renal function and electrolytes are routinely determined
• Consider checking Thyroid Function Tests to rule out hyperthyroidism
• Consider checking hemoglobin and hematocrit to rule out anemia
