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.

Palpitations of the heart. Palpitations are a sensation or awareness of your heart beating. They may feel like your heart is racing, thumping or skipping beats. Almost everyone has had palpitations at some time in their life. They are usually associated with an abnormal heart rhythm (arrhythmia). Palpitations may have no obvious cause, but can be triggered by: physical activity; emotional stress; caffeine; nicotine. An occasional palpitation that does not affect your general health is not usually something to worry about.
