Heart disease is the leading cause of death in the Western world and consequently the study of normal and pathological heart behavior is an active research area. In particular, the study of the shape and motion of the heart is important because many heart diseases are strongly correlated to these two factors. The human heart is composed of two separate pumps: a right heart that pumps the blood through the lungs and a left heart that pumps the blood through the peripheral organs. In turn, each of these "hearts" is a two-chamber pump composed of an atrium and a ventricle. Special mechanisms in the heart provide cardiac rhythm and transmit action potentials throughout the heart muscle to cause the heart's rhythmic relaxation (diastole) and contraction (systole).
心脏病是西方世界的主要死因，因此对正常和病理心脏行为的研究是一个活跃的研究领域。特别是，心脏形状和运动的研究很重要，因为许多心脏病与这两个因素密切相关。人类心脏由两个独立的泵组成：一个右心将血液泵入肺部，一个左心将血液泵入外周器官。反过来，每个这样的“心脏”都是一个由心房和心室组成的双腔泵。心脏中的特殊机制提供心律，并将动作电位传递到整个心肌，导致心脏有节奏地舒张（舒张期）和收缩（收缩期）。
