Fifty patients 70 years of age and older underwent coronary artery bypass surgery for disabling angina pectoris or congestive heart failure or both (two quadruple, 11 triple, 25 double grafts, 12 single). Twenty additional procedures were done (11 mitral valve replacements for papillary muscle dysfunction, six ventricular aneurysmectomies, four aortic valve(More)
One hundred three patients with persistent sinus bradycardia were evaluated electrophysiologically and followed prospectively for a mean of 4.6 years. The 5-year survival rate was 74.8%, not significantly different from the 72% rate in the general population with similar age and sex distribution. Forty-one patients had abnormal corrected sinus-node recovery(More)
Of 1125 patients with acute myocardial infarction admitted to Mount Sinai Medical Center in 1971 and 1972, 292 (28.8 percent) had intraventricular conduction defects. In 210 of the 292 patients with intraventricular conduction defect, it was possible to determine if the conduction defect, was present before the infarction (Group 1, 123 patients) or(More)
A 36-year-old man developed severe weakness, palpitation, and diaphoresis 30 minutes after eating wonton soup. On admission to the hospital he was found to have ventricular tachycardia. He was given lidocaine intravenously and the rhythm converted to normal with the three minutes. It was concluded that monosodium L-glutamate might produce potentially(More)
BACKGROUND A low-carbohydrate diet remains controversial, especially in patients with arteriosclerotic heart disease. HYPOTHESIS This study was undertaken to evaluate the effect of a low-carbohydrate diet on the lipid levels in obese patients with known arteriosclerotic heart disease on chronic statin therapy. METHODS Thirty-eight overweight patients(More)
22 patients with syncope and significant aortic stenosis underwent electrophysiological evaluation in addition to the hemodynamic study. Abnormalities of impulse formation or conduction were present in 12 patients. 6 patients demonstrated HV times greater than or equal to 55 msec. There was no correlation between the aortic valve gradient and the HV(More)
One hundred consecutive patients admitted to our cardiology service with the suspected diagnosis of acute myocardial infarction were evaluated with serical enzyme and isoenzyme determinations in an attempt to develop the medically and financially optimal combination of enzyme tests. In patients with onset of chest pain less than 24 hours before admission,(More)
Ten years ago a clinical method of recording the electrical activity of the His bundle in man with transvenously inserted electrodes was described. His bundle recording has permitted the breakdown of the P-R interval into three conduction intervals, i.e., intraatrial (P-A), A-V nodal (A-H), and His-Purkinje system (H-V). His bundle studies have demonstrated(More)
