Symptom-limited cardiopulmonary exercise testing was performed in 37 patients with mitral stenosis (MS) without significant coronary artery stenosis to evaluate factors affecting ST depression in exercise electrocardiograms. The degree of ST depression was not associated with gender or exercise tolerance. The incidence of significant ST depression was higher in the patients receiving than in those not receiving digitalis (P < 0.05). In addition, the patients with atrial fibrillation and a higher heart rate response were more likely to have a high prevalence of significant ST depression than those with sinus rhythm and a lower response (P < 0.05). We concluded that atrial fibrillation, a higher maximum heart rate, and oral digitalis administration were involved in ST depression during exercise testing in patients with mitral stenosis without coronary heart disease.

Spontaneous conversion to sinus rhythm after prolonged atrial fibrillation is uncommon, with only 11 recorded cases to our knowledge in the English language literature. We report four cases of spontaneous conversion to an organized atrial rhythm (either sinus rhythm or atrial tachycardia with block) after nine to 16 years of established atrial fibrillation. One case was due to a toxic reaction to digitalis. In the other three cases there was no apparent reason. M-mode and two-dimensional echocardiography in three patients showed an akinetic and noncontractile left atrium in each case. This lends support to an earlier hypothesis that complete fibrosis of the left atrium may be responsible for the conversion from atrial fibrillation.
