Overview

Premature atrial contractions occur frequently in subjects with normal heart; however, patients with structural heart disease and coronary heart disease are at increased risk. Alcohol and coffee are considered potential precipitants of PACs. PAC's may also be more common in other medical conditions such as chronic renal failure and chronic pulmonary disease.
