Any process that stops, prevents or reduces the frequency or rate of heart contraction. The multicellular organismal process by which the heart decreases in volume in a characteristic way to propel blood through the body. Any process by which an organism modulates its heart rate at different values with a regularity of approximately 24 hours. Any process that modulates the frequency or rate of heart contraction. Any process that modulates the frequency, rate or extent of a system process, a multicellular organismal process carried out by any of the organs or tissues in an organ system. Any process that modulates the frequency, rate or extent of heart contraction. Heart contraction is the process by which the heart decreases in volume in a characteristic way to propel blood through the body. Any process that modulates the frequency, rate or extent of any biological process, quality or function. Any process that modulates the frequency, rate or extent of a biological quality. A biological quality is a measurable attribute of an organism or part of an organism, such as size, mass, shape, color, etc. Any process that activates or increases the frequency or rate of heart contraction. The regulation of the rate of heart contraction mediated by chemical signaling, hormonal, autocrine or paracrine.
