[Predictive value of ventricular extrasystole in the exertion test and its relation to the magnitude of coronary damage].
The predictive value of ventricular arrhythmias, associated with treadmill exercise testing was evaluated in 115 patients undergoing coronary angiography and left ventriculography within three months of the exercise test. 39 patients with ventricular arrhythmias (at least one premature ventricular complex, paired complex or ventricular tachycardia) had a higher or multivessels disease than the patients without ventricular arrhythmias (P less than 0.05). This study demonstrated that ventricular arrhythmias detected at exercise testing are related to the extent of coronary artery disease, and the presence of the left ventricular disfunction.
