Induced tachycardia demonstrated myocardial hypoxia and anaerobic metabolism in a 48-year-old woman with angina pectoris and normal coronary arteriograms.
Case Report (n=1)
Although coronary arteriograms of a 48-year-old woman with exertional chest pain typical of angina pectoris and an abnormal exercise electrocardiogram were normal, myocardial hypoxia and anaerobic metabolism were demonstrated during induced tachycardia and are proposed as the basis of the angina pectoris. A cause of impaired myocardial oxygen metabolism other than obstructive disease of visible coronary arteries is suggested.
Neill et al. (Thu,) conducted a case report in Angina pectoris with normal coronary arteriograms (n=1). Induced tachycardia was evaluated on Myocardial hypoxia and anaerobic metabolism. Induced tachycardia demonstrated myocardial hypoxia and anaerobic metabolism in a 48-year-old woman with angina pectoris and normal coronary arteriograms.
