Electrocardiography is the process of producing an electrocardiogram (ECG or EKG), a recording – a graph of voltage versus time – of the electrical activity of the heart using electrodes placed on the skin. These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle (heartbeat).

The Fontan operation was first performed in 1968. Since then, this operation has been performed on thousands of patients worldwide. Results vary from very good for many decades to very bad with a pleiad of complications and early death. A good understanding of the physiology is necessary to further improve results. The Fontan

The Fontan Circulation. Since the Fontan operation was first proposed as a corrective procedure for tricuspid atresia, it has evolved to become the definitive palliative surgery for individuals born with single ventricle physiology or for those in whom a biventricular repair is not feasible.

Personalized medicine is the science of individualized prevention and therapy. The notion that “one size fits all” has been replaced by the idea of patient-tailored health care. Within this paradigm,

Failing Fontan Etiology. Ventricular Failure Even in ideal Fontan physiology, cardiac output in these individuals is only 70% of normal patients.9,10,11 The Fontan physiology is a pressure-loaded system. This is secondary to increased systemic vascular tone, decreased venous capacitance, and a baseline PVR greater than a biventricular patient.
