the Maximum physical activity. Intermediate reaction

you in section: the Maximum physical activity

Before the test beginning to the surveyed remove an electrocardiogram in 12 assignments and on Nebu, define a pulse rate and arterial pressure. Then surveyed makes 10-14 rising during 30 with. After loading every minute write down an electrocardiogram (during 10 mines), each 2 mines define a pulse rate and arterial pressure. Except the specified indicators consider also the general reaction of an organism. At carrying out of this test distinguish three basic types of reaction of an organism on loading (V.S.Gasilin, 1976). at physiological reaction: the electrocardiogram does not change, state of health surveyed good, the pain in the field of heart is not present, increase of pulse to 8-10% from the initial is possible. Intermediate reaction is characterised by the fast fatigue, quickly passing unpleasant sensations in the field of heart, small decrease in a voltage of tooth T and displacement to 0,5 mm of segment S - T, sometimes individual ekstrasistolami. At pathological reaction there is a pain in the field of heart or behind a breast, an expressed weariness, negative tooth T, displacement of interval S - T to 1 mm and more, frequent ekstrasistoly and other infringements of a warm rhythm and conductivity.

Pathological reaction to test ' sits down-rise ' can to be a sign of coronary insufficiency. At persons with intermediate reaction to loading it is necessary to conduct repeated research on veloergometre.
