Cardiac Resynchronization Therapy
Heart failure is the result of a damaged heart muscle. A heart with damaged muscle is a less effective pump, which results in a reduced ability to supply oxygen to meet the needs of the body and brain.
Selected patients with moderate to severe heart failure may benefit from Cardiac Resynchronization Therapy (CRT). CRT, in combination with stable optimal medical therapy, may help the lower chambers of the heartbeat together and improve the heart's ability to supply blood and oxygen to the body. CRT is designed to help the two lower heart chambers, the right and left ventricles, beat at the same time in a normal sequence treating ventricular dysynchrony.
CRT is similar to a pacemaker. It is placed (implanted) under the skin of the upper chest. CRT is delivered as tiny electrical pulses to the left and right ventricles through three or four leads (soft insulated wires) that are inserted through the veins to the heart. These tiny impulses are small and not normally detected
CRT may be prescribed for someone suffering from heart failure but it is not a replacement for drug therapy. It is recommended that anyone choosing to receive CRT continue taking medications as prescribed by their physician.
