Assessment of ventricular function in coronary artery disease by means of atrial pacing and exercise.

摘要: Abstract Left ventricular hemodynamics were studied in 20 patients with coronary artery disease and 7 normal subjects during atrial pacing exercise. Angina developed 13 exercise, but was absent both periods. Ventricular function curves each stress, using left end-diastolic pressure stroke work, clearly distinguished the 3 groups. During those without angina there a downward movement on curve, group shift to depressed curve. exercise an augmented angina, upward original Exercise are useful evaluating hemodynamic disease. When ischemic symptoms induced by either or they associated depression of performance. is not proyoked, only demonstrates abnormal since response indistinguishable from that group.
