BACKGROUND Differentiating occlusion of the circumflex branch of the left coronary artery (also called the circumflex artery) from occlusion of the right coronary artery is often difficult because either may be associated with a pattern of acute inferior myocardial infarction on the electrocardiogram. Also, patients who tolerated placement of a tube cap had the lowest mean secretion level, and those who tolerated only light finger occlusion had the highest; likewise, most patients with normal secretion levels tolerated a capped tube, and a plurality of patients with profound secretion levels tolerated only light finger occlusion. We determined ST-segment elevation, a measure of myocardial ischemia heart rate, and arrhythmia incidence during occlusion from continuous electrocardiograms. |
