Myocardial calcification as a rare cause of congestive heart failure: a case report.

Myocardial calcification is a manifestation of either metastatic or dystrophic calcium deposition in the myocardium. Dystrophic calcification of the myocardium is most commonly seen in long-term survivors of substantial myocardial infarctions. Current literature has reported only 3 cases of myocardial calcification with normal coronary arteries.

Coronary artery spasm and myocardial infarction in a patient with normal coronary arteries: temporal relationship to pseudoephedrine ingestion.

A 28 yr-old male presented with chest pain and acute ST elevation following ingestion of pseudoephedrine. The pain and electrocardiographic changes disappeared after the administration of sublingual Nitroglycerin. Myocardial enzymes did show some evidence for myocardial necrosis.

Cyclical variation of the heart rate in sleep apnoea syndrome. Mechanisms, and usefulness of 24 h electrocardiography as a screening technique.

400 sleep-apnoeic patients with an intact autonomic nervous system underwent twenty-four-hour electrocardiography with simultaneous polygraphy recording at night. At onset of sleep apnoea all showed progressive bradycardia, followed by abrupt tachycardia on resumption of breathing. The electrocardiographic pattern, which is identifiable by computer analysis, can be used as a screening tool for sleep apnoea; it was not seen in controls without sleep apnoea syndrome.
