The multicellular organismal process by which the heart decreases in volume in a characteristic way to propel blood through the body. A process whereby force is generated within muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. Any process that increases the frequency, rate or extent of cardiac muscle contraction. The flow of blood through the body of an animal, enabling the transport of nutrients to the tissues and the removal of waste products. Any process that modulates the frequency, rate or extent of cardiac muscle contraction. A process whereby force is generated within striated muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. Striated muscle is a type of muscle in which the repeating units (sarcomeres) of the contractile myofibrils are arranged in registry throughout the cell, resulting in transverse or oblique striations observable at the level of the light microscope. Any process that stops, prevents or reduces the frequency, rate or extent of cardiac muscle contraction. Muscle contraction of cardiac muscle tissue. A circulatory system process carried out by the heart. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.
