The patients were divided into two groups: group A, with no arrhythmias at rest, and group B with arrhythmias at rest. All classic nosographic arrhythmias were considered. In some teenager patients with arrhythmias at rest and no organic cardiopathy, anomalies disappeared during stress, showing the benignity of the phenomenon. Supraventricular stress induced arrhythmias has 1.2% of incidence in normal subjects, but 81% in heart disease patients. Supraventricular tachycardia was induced in 6 patients. Ventricular stress induced arrhythmias are found in 4.9%. Two cases of sudden death occurred in our groups. | lld:pubmed |
