Paroxysmal Nocturnal Dyspnea (PND)


Updated June 18, 2014

Definition: Paroxysmal nocturnal dyspnea, or PND, is dyspnea (shortness of breath) that awakens you from sleep. People who have PND will awaken suddenly, gasping for air and needing to sit up. After several minutes, the dyspnea goes away.

PND is very often a sign of significant heart failure, and this symptom should always be evaluated by a physician.
