- Heart Murmur
With a stethoscope, a doctor can listen to your chest for the distinct sound of a new heart murmur or a change in the sound of an old heart murmur. Heart murmurs are caused by the sound of faulty heart valves and by certain defects in your heart. [texasheart.org]
Have a new heart murmur. Endocarditis can cause a new or additional heart murmur, or unusual sound in your heartbeat, or changes to an existing one. See changes in your skin. Tiny bumps or spots may show up on your hands or feet. [webmd.com]
