A cardiac resynchronization heart device sends tiny electrical pulses to the lower chambers of your heart so it can pump blood more efficiently.
CRT is a heart failure treatment option in which an implantable heart failure device helps the lower chambers of the heart to beat in rhythm.
The heart device is surgically placed under the skin, typically just below the collarbone.
