Staged ladder for measuring cardiac chronotropic functions

Abstract

The invention relates to a device for measuring cardiac functions, in particular to a staged ladder for measuring cardiac chronotropic functions, which comprises a bottom plate, wherein the upper surface of the bottom plate is provided with a staged ladder and a sliding device along the front part in the length direction of the bottom plate; the staged ladder comprises three layers of ladders, wherein a first-stage ladder, a second-stage ladder and a third-stage ladder are respectively arranged from bottom to top, i.e. the second-stage ladder is arranged above the first-stage ladder, and the third-stage ladder is arranged above the second-stage ladder; the height of the first-stage ladder is 25cm; the height of the second-stage ladder and the height of the third-stage ladder are 20cm; the first-stage ladder is fixed on the bottom plate; the second-stage ladder and the third-stage ladder slide along the length direction of the bottom plate through the sliding device; a locking device is arranged between the back side surfaces of each of the ladders; the sliding device comprises slide ways and a slide way fixing frame fixed on the bottom plate; the slide ways are respectively arranged at the contact part of the first-stage ladder and the second-stage ladder and the contact part of the second-stage ladder and the third-stage ladder; and the slide ways are fixed on the slide way fixing frame.

Description

technical field [0001] The invention relates to a cardiac function measuring device, in particular to a cardiac chronotropic function measuring ladder. Background technique [0002] The chronotropic function of the heart refers to the function that the heart rate can be appropriately increased according to the increase of the body's metabolic needs when the human body is exercising, or under the action of various physiological and pathological factors. When the heart rate cannot increase with the body's metabolic needs to a certain extent or cannot meet the body's metabolic needs, it is called chronotropic incompetence (CI). Coronary heart disease (CHD) is the cardiovascular disease with the highest morbidity, mortality and disability, and has become an important disease that endangers people's health and even leads to death. Therefore, its early prevention, accurate diagnosis and timely treatment have important clinical significance. In recent years, a large amount of dat...

Problems solved by technology

At present, overseas CI measurement mostly relies on the electrocardiogram exercise flat panel. The defect of the electrocardiogram exercise tablet is that the subject is in a passive motion state during the inspection process. At the same time, it is noisy and expensive when used.

However, domestic CI measurement is rarely carried out, which is related to factors such as the high price and complicated operation of the electrocardiogram exercise tablet
