Nitroglycerin improves the exercise performance of patients with coronary heart disease. A retrospective study of data collected while monitoring 103 such patients was focused on the various types of arrhythmia and the effects of nitroglycerin on the frequency of occurrence. After nitroglycerin administration, occurrences were fewer. This applied more to angina patients than to those with healed myocardial infarction.
