Signal Detection and the “Cardiac Arousal Cycle”
Psychophysiology, 1972ABSTRACTThe hypothesis was tested that different phases of the cardiac cycle would be associated with differences in either sensory capacity or response bias, as estimated by signal detection analyses. Each of 10 subjects was given 800 signal (SN) and 800 non‐signal (N) trials randomly distributed throughout the cardiac cycle.

Indoor Cycling for the Cardiac Patient
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.

Detection of the Heartbeat and Events in the Cardiac Cycle
Psychophysiology, 1985ABSTRACTIn previous studies the heartbeat has been defined in terms of individual components of the cardiac cycle (e.g., the R‐wave or the ventricular contraction) as specified by the experimenter, and subjects have been classified as nondetectors if they failed the task set by the experimenter.

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.

The cardiac cycle: regulation and energy oscillations
American Journal of Physiology-Heart and Circulatory Physiology, 1983Cyclical changes in energy-related metabolites were observed in glucose-perfused but not pyruvate-perfused isolated working rat hearts. A chronological study of various phases of the cardiac cycle indicated maximum changes in metabolites occurred at half time to peak pressure (dF/dtmax).

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.
