Whatâs the problem? Pulmonary regurgitation (PR, also called pulmonic regurgitation) is a leaky pulmonary valve. This valve helps control the flow of blood passing from the heart to the lungs.

Heart palpitations. Palpitations are feelings or sensations that your heart is pounding or racing. They can be felt in your chest, throat, or neck. The heart's rhythm may be normal or abnormal when you have palpitations. Normally the heart beats 60 to 100 times per minute. The rate may drop below 60 beats per minute in people who exercise routinely or take medicines that slow the heart.
