internal medicine. The branch of medicine that deals with the diagnosis and treatment of diseases affecting the internal organs of the body, especially in adults.
Heart murmurs can generally be divided into two categories: 1  Murmurs that are not due to structural problems in the heart also called innocent murmurs or functional murmurs..  Murmurs which are due to a structural problem of the heart (such as a hole in the heart, a narrowed heart valve or a leaky heart valve). These murmurs require further evaluation and follow-up with a cardiologist.
Heart murmurs are sounds during your heartbeat cycle â such as whooshing or swishing â made by turbulent blood in or near your heart. These sounds can be heard with a stethoscope. A normal heartbeat makes two sounds like lubb-dupp (sometimes described as lub-DUP), which are the sounds of your heart valves closing. Heart murmurs can be present at birth (congenital) or develop later in life.
