Detection of coronary stenoses by stress echocardiography using a previously implanted pacemaker for ventricular pacing: Preliminary report of a new method
infarction. HYPOTHESIS To detect significant coronary stenosis in patients with previouslyimplantedpacemakers, we tested a newstressechocardiographymethodusing incremental ventricularpacing by already implantedpacemakers. METHODS We studied prospectively 25 consecutive patients who underwent stressechocardiography with increasing ventricularpacing up to either 85% of the age-predicted maximal
