CRHF
Cardiac Rhythm and Heart Failure (CRHF) is the oldest and largest of Medtronic's business units. Our work in heart rhythm therapies dates back to 1957, when co-founder Earl Bakken developed the first wearable heart pacemaker to treat abnormally slow heart rates. Since then, we've expanded our expertise in electrical stimulation to treat other cardiac rhythm diseases. We've also moved into overall disease management by adding diagnostic tools and building monitoring capabilities into many of our devices.
