Cancellation of juxtacardiac esophageal electrocardiograms, as demonstrated in this study, indicates certain limitations of the equivalent cardiac dipole hypothesis. A new and more fundamental theory developed here shows that in large measure cancellation occurs because the cancellation network is in effect a relatively insensitive electrocardiographic connection, and because there is always pr...
The study comprised 196 healthy young adults (100 men, 96 women) between the ages of 20 and 30 years, many ofwhom were university undergraduates and pupil nurses. A full clinical history was followed by a detailed physical examination, and subjects who were not physically healthy were excluded from the study. A 12-lead electrocardiogram was recorded at least 24 hours after the last meal, with n...
To evaluate the application of radionuclide infarct scintigraphy to diagnose myocardial infarction after revascularization, we obtained postoperative technetium 99m pyrophosphate myocardial scintigrams, serial electrocardiograms and CPK-MB isoenzymes in ten control and 51 revascularized patients. All control patients had negative electrocardiograms and scintigrams, but eight had positive isoenz...
