The Cardiac Arrhythmias

Cardiocirculatory Performance in Atrial Flutter

“…per square meter of body surface area and in respiratory gas exchange ratios was 0.11) and indicated a similar basal state, one can conclude that in all instances after conversion, the resting cardiac output rose significantly (table 2). Obviously digitalization and relief of congestive failure must have contributed to a rise in cardiac output in the last two subjects shown in table 2 and figure 9 (Case 542, 695), but in the first three, these factors were not operative as cardiac output after the glycoside was administered were approximately of the same magnitude and achieved much the same level of flow. In the patient with atrial flutter (W. W., Case 477), on the left in figure 11, who is representative of four so studied (table 4) 2, and fig.…”

Myron Prinzmetal 1908–1987: The man behind the variant angina

“…From 1950 he published a large number of papers on the auricular arrhythmias, making use of high-speed cine-electrocardiography [4][5][6][7][8][9][10]. These included the conformation of the circus movement in atrial flutter, first suggested by Sir Thomas Lewis; the mechanism of ventricular activity; the origin of the RS-T segment changes in acute myocardial infarction; and the nature of spontaneous atrial fibrillation.…”

“…Many other articles and several books were to follow until illness forced him to retire from research and practice [12]. Myron Prinzmetal died on January 8,1987. With his first wife Blanche Keiler he had four children, Byron, Anita, William, and Cynthia.…”
