Eighty seemingly healthy subjects between 21 and 30 years old were studied by maximal stress test using a bicycle ergometer to induce cardiac arrhythmias and establish the clinical diagnosis. The maximal heart rate attained was 93.7 % of the one programmed. None of the subjects studied presented with arrhythmias as observed in the ECG at rest. During exertion, 2 patients presented with isolated premature ventricular complexes, and 4 with premature supraventricular complexes, 2 of them with aberrant conduction. During recovery 6 cases had premature supraventricular complexes, most of them isolated. There was a case in which arrhythmia was frequent up to the third minute of recovery, and it was possible to reproduce it when repeating the test. Cardiac arrhythmias observed during the stress test are consistent with the ones of a healthy population.
