Comparative study of exercise-induced ventricular arrhythmias in normal subjects and patients with documented coronary artery disease

Exercise induced ventricular arrhythmias Angiographic correlation with the severity of coronary artery disease.

“…20) We have also observed, even in patients with severe CAD, the disappearance of ventricular arrhythmias during exercise.10),13), 35) In agreement with other studies,10),12),35),36) ventricular arrhythmias were more frequently observed in the recovery period, but this was not associated with more severe CAD in comparison to patients with ventricular arrhythmias appearing during exercise. Furthermore, the occurrence of EIVA at heart rates equal to or less than 130 beats/min, as was generally the case in our study, confirms the observations by McHenry et al, 12) who showed that patients with CAD develop ventricular arrhythmias at lower heart rate than normal subjects showing ventricular ectopy on exercise.9),11),12),14)…”

Incidence and Prognostic Implications of Severe Ventricular Arrhythmias during Maximal Exercise Testing

“…There are very few detailed reports in the literature concerning the incidence of severe ventricular arrhythmias during MET -table II (2,3,10,14,15]. As far as the incidence of VT is concerned, our data are similar to those of other small series and one can thus expect one such event in 0.5% of all maximal exercise tests performed in populations with a high preva lence of CAD.…”

Ventricular tachycardia due to cardiac ischaemia: assessment by exercise electrocardiography

“…The incidence of ischaemic ventricular tachycardia will vary depending on the population studied and the intensity of diagnostic investigation. Nevertheless, exercise-induced ischaemic ventricular tachycardia is found in fewer than 10o0 of patients with chronic ischaemic heart disease.8 9 We think the incidence would be higher if exercise tests were not stopped when certain patterns of ventricular extrasystoles were seen.…”
