Ergonomics is a science that links people and their work. It is the study of natural laws governing work (“ergon”, meaning work and “nomos” meaning law). It studies work performance with emphasis on worker safety and productivity amidst human abilities, limitations and characteristics. The focus of ergonomics is on “How to do” to prevent injury, dysfunction and morbidity.

Cardiovascular ergonomics may also be called as “cardio-economics” where the cardiovascular system is made to work economically reducing the myocardium oxygen demand to meet the load under varied situations. Ergonomics uses physiological responses to address both efficiency and safety issues.

Cardiac dynamics: Cardiovascular system couples with the musculoskeletal system and is interlinked with various body compartments such as thorax, abdomen, pelvis, and peripheries to provide optimum function.
