The increased frequency of acute myocardial infarction during summer months in a warm climate
Autor: William Barris, Howard E. Heyer, H.C. Teng
Publikováno v: American Heart Journal. 45:741-748
The seasonal and monthly frequency of occurrence in a series of 1,386 cases of proved myocardial infarction is reported from Dallas, Texas. The greatest number of cases occurred in the summer months, and the lowest number of cases in the winter month

Variations in the duration of phases of the cardiac cycle in normal hearts as studied by the electrokymograph
Autor: Julian K. Acker, Howard E. Heyer, E.E. Eddleman, Kathryn Willis, Ernest Poulos
Publikováno v: American Heart Journal. 40:485-503
The usefulness of the electrokymograph as a tool in the study of cardiovascular dynamics has been demonstrated by several workers in the past few years. 1.2 3 Much of the work has been concerned with the contours of tracings obtained by recording the

The effect of posture on the cardiac cycle, postero-anterior cardiac diameters, and apparent stroke volume as studied by the electrokymograph
Autor: E.E. Eddleman, Howard E. Heyer, Kathryn Willis
Publikováno v: American Heart Journal. 40:504-521
The purpose of this paper is to record observations on the effect of positional changes on the duration of the various physiological phases of the cardiac cycle, as well as to record changes in posteroanterior diameters of the heart caused by the ass

Heart Block of thirty-two years' duration
Autor: Edward Kessler, Howard E. Heyer
Publikováno v: American Heart Journal. 42:900-905
A case of heart block is presented which showed a high degree of block for approximately twelve years, followed by first-degree block for the next twenty years. The patient remained in fairly good health up to the time of the report. The onset of the

Abnormalities of the respiratory pattern in patients with cardiac dyspnea
Autor: Howard E. Heyer
Publikováno v: American Heart Journal. 32:457-467
1. 1. Pneumographic tracings of respiration revealed a similar type of distortion and prolongation of the expiratory phase in cardiac patients with pulmonary congestion and in patients with allergic asthma. Expiration in these patients did not underg

The present status of electrokymography
Autor: Howard E. Heyer, Bert R. Boone
Publikováno v: American Heart Journal. 44:458-480
The development of the electrokymograph has made it possible to record heart border motion, as well as changes in cardiac density, with accuracy and comparative ease. The instrument possesses dual potentialities as both a diagnostic clinical aid and
