Studies of the cardiovascular system were made among 26-mile marathon runners after at least five years of physical training. Studies made with the subjects at rest showed an electrocardiogram ...

The effects of drugs that produce known hemodynamic alterations were assessed on externally recorded pulse waves, heart sounds, and the relationship of these to each other and to the electrocardiogram ...

Hemodynamic changes associated with diastolic hypertension were investigated using 50° head-up for 52 untreated hypertensive patients not in cardiac failure, and for 17 normotensive subjects. Normals ...

Certain temporal patterns of A-V and V-A transmission in experimental preparations resemble phenomena attributed to "supernormal" conduction in the clinic. Detailed study of the properties of the A-V ...

Defects in the muscular portion of the interventricular septum are frequently multiple. Although their incidence is significant, scant attention has been paid them as a distinct entity. This report ...

It should be clearly understood that no evidence was uncovered to indicate an unequivocal etiology for this uncommon disease. One is tempted to qualify "uncommon" in that it no longer connotes the ...

The role of cardiac troponins as indicators of irreversible cell injury is well established. 8 Although in myocardial infarction circulating troponins result from continuous degradation of the ...

With the advancements of molecular genetics and the identification of mutations in the genes encoding the cardiac ryanodine receptor and cardiac calsequestrin 2 in patients with CPVT, the central role ...
