Diagnosis of arrhythmias begins with a Holter monitor that can identify the type of arrhythmia. This is followed by a cardiac catheterization to find the aberrant cells generating the arrhythmia. The patient is then recommended for open-heart surgery to remove the cells generating the arrhythmia.
Diagnosis of chronic heart failure is demonstrated by a cardiac catheterization or nuclear medicine study. During cardiac catheterization, the patient's cardiac function will be measured by cardiac output, ejection fraction and cardiovascular pressures. A nuclear medicine study can demonstrate areas of myocardium that are damaged. Muscle that is akinetic (does not move) will be identified. This information allows the surgeon to identify candidates for myocardial resection.
This is major surgery and should be the treatment of choice only after medications have failed and the use of an implantable cardioverter-defibrillator (a device that delivers electrical shock to control heart rhythm) has been ruled out along with medical therapy.
Prior to surgery, the physician will explain the procedure and order blood tests of the formed blood elements and electrolytes.

Other Information
Myocardial resection is a surgical procedure in which a portion of the heart muscle is removed.
Purpose
Myocardial resection is done to improve the stability of the heart function or rhythm. Also known as endocardial resection, this open-heart surgery is done to destroy or remove damaged areas of the heart that cause life-threatening heart rhythms. This procedure is often performed in people who have had a heart attack, in order to prevent future rapid heart rates. It is also used in people who have Wolff-Parkinson-White syndrome (a condition resulting in abnormal heart rhythm).
After receiving a general anesthetic, an incision will be made in the chest to expose the heart. When the exact source of the abnormal rhythm is identified, it is removed. If there are areas around the source that may contribute to the problem, they can be frozen with a special probe to further insure against dangerous heart rates. The amount of tissue removed is so small, usually only 2 or 3 millimeters, that there is no damage to the structure of the heart. On some occasions, aneurysms of the heart wall are removed as well.
Other Information
If you need heart surgery, you don't want a surgeon who only got a C in medical school. The same principle applies in helping people with mental illnesses.
