JAMA: The Journal of the American Medical Association, 1971To the Editor.— When the patient with coronary disease is "back on his feet" and regular daily exercise is considered essential to keeping him there, I prescribe indoor cycling, and the prescription is as specific as any written for his medication. There are many reasons for preferring indoor cycling to walking, swimming, jogging, and golf.

Electromechanical Intervals of the Fetal Cardiac Cycle
Clinics in Obstetrics and Gynaecology, 1979The measurement of electromechanical intervals of the fetal cardiac cycle may be useful in the evaluation of cardiac status, since they are based upon sound physiological principles. Studies of EMIs in the human fetus are currently in their infancy and clinical evaluation of their usefulness awaits the development of adequate data acquisition ...

Influence of menstrual cycle on cardiac performance
Maturitas, 2007The purpose of this study was to investigate the relationship between endogen sex hormone levels and myocardial performance in two different phases of menstrual cycle.The relationships between cardiac performance and sex hormone levels in menstrual cycle have not yet been clearly identified.Twenty-seven women at the age of 19-42 years (mean 24.11+/-6 ...

The Wright Cardiac Cycle Table: A Novel Tool to Teach the Cardiac Cycle
The FASEB Journal, 2017The Wiggers Diagram has been the standard tool for teaching the events of the cardiac cycle for nearly 100 years. However, as it often displays related cardiac cycle events on different figures in the diagram, many students have trouble grasping how these components work together to pump blood into arteries.

Reaction time as a function of the cardiac cycle
British Journal of Psychology, 1980Simple reaction times to auditory stimuli varied with the phase of the cardiac cycle in which the stimulus was presented. Longitudinal studies showed that stimuli triggered at different phases in the ECG gave rise to different rhythmic patterns of behaviour.

The manifold functions of the blood described in some of the other chapters (cf. Chaps. 88, 90–99) can only be fulfilled if the blood circulates continuously through the body. The main driving force for the movement of blood is provided by the mechanical activity of the heart.
