Treadmill exercise electrocardiography and spirometry was recorded in 61 patients (aged from 5 to 23 years) who underwent corrective surgery for tetralogy of Fallot. The Bruce-protocol and a modified interval-protocol were compared to find out their ability to induce arrhythmias. Supraventricular arrhythmias were predominantly provoked by the interval-protocol while maximal exhaustion is often necessary for inducing ventricular arrhythmias which we found in 23% of our patients. Most of them were seen in the periods of recovery between or after the exercise. We propose a combination of both protocols, which will be compared with established forms of exercise-testing in further studies. The results of rhythm analysis of consecutive exercise tests in one patient after surgical repair could possibly be compared by using an "arrhythmia score" which tries to indicate the severity of different forms of arrhythmias. The values of maximal heart rate, oxygen consumption and endurance time recorded at maximal exercise (Bruce-protocol) were about 15% lower than correspondent values of healthy persons found by other authors.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D010092	Oximetry	The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry.	Pulse Oximetry,Oximetry, Pulse,Oximetries,Oximetries, Pulse,Pulse Oximetries
D010807	Physical Endurance	The time span between the beginning of physical activity by an individual and the termination because of exhaustion.	Endurance, Physical,Physical Stamina,Stamina, Physical
D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.

D005117	Cardiac Complexes, Premature	A group of cardiac arrhythmias in which the cardiac contractions are not initiated at the SINOATRIAL NODE. They include both atrial and ventricular premature beats, and are also known as extra or ectopic heartbeats. Their frequency is increased in heart diseases.
