Heart failure patients have symptoms of shortness of breath and body swelling caused by decreased pumping of blood from the heart. Initial management includes treating underlying cause, adopting a healthy lifestyle and taking medications.
Patients with persistent symptoms despite the above treatments may consider echocardiography. It is essentially an implantable cardiac pacemaker that consists of a battery-powered generator and leads which connect the generator to the patient’s heart. But there is a special lead placed in the left heart, so that the device can stimulate both the left and right heart in a coordinated (synchronized) manner. The synchronized contraction will increase pumping of blood from the heart. Recent studies have shown that in selected groups of patients, CRT improves heart failure symptoms, quality of life, exercise capacity and heart function.
