Pies: A dog’s heart beats up to 120 times per minute, or 50% faster than the average human heartbeat of 80 times per minute

Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide. It is also modulated by numerous factors, including genetics, physical fitness, stress or psychological status, diet, drugs, hormonal status, environment, and disease/illness, as well as the interaction between these factors. It is usually equal or close to the pulse rate measured at any peripheral point. The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. An ultra-trained athlete may have a…

Methodological development of a pneumatic artificial muscle-driven left ventricular simulator using interpretive structural modeling.. Mock circulation systems can replicate a wide range of cardiac operating scenarios, such as cardiovascular diseases, particularly muscular dysfunctions. These systems are operated by sophisticated control algorithms which require complex driver and data acquisition systems, whereas animal models raise ethical concerns. Therefore, there is a need for novel testbeds to overcome the challenges in the existing systems. The aim of this study is to develop a less complex and realistic left ventricular (LV) simulator. The Interpretive Structural Modeling (ISM) appr…
