Hyperfunction of the Heart Isotonic

Content:

Isotonic cardiac hyperfunction is a physiological condition characterized by an increase in the volume of blood pumped by the heart per unit of time. This condition is associated with an increase in the intensity of the heart. Isotonic cardiac hyperfunction is typical for athletes experiencing significant physical activity. Under conditions of increased physical activity, the layer of blood in the walls of the capillaries becomes thinner, the lumen of the vessels narrows, and the tone of the heart increases, which in turn leads to a significant increase in its performance. The faster the blood moves, the less resistance it experiences and the more its volume penetrates into the body. Hypertrophy (increase in size) of the heart muscle occurs under constant loads, but it is not always a consequence of muscle activity. Hypertensive states are accompanied by systolic ejection of a larger volume from the left ventricle, which may cause overload. This is accompanied by a number of changes in tissues that need more oxygen, and other body reactions, such as dilation of blood vessels
