Diagnosis of Obstructive Coronary Disease by Maximal Exercise and Atrial Pacing

摘要: The reliability of graded maximal exercise treadmill testing and right atrial pacing in diagnosing significant obstructive coronary artery disease was evaluated 74 consecutive patients referred to a cardiac unit with chest pain consistent angina pectoris. results pacing, regard the presence or absence patient's characteristic discomfort ischemic ST segment depression, were compared findings determined by selective arteriography.
