Dicrotic Rise

DICROTIC RISE (Ohmic rise, Dicrotic peak). - this is the case when the curve of a change over time of any quantity increases very quickly, reaches a maximum and just as quickly falls to the initial level. This is the most characteristic type of wave rise on the electrocardiogram (ECG) in case of acute disruption of the blood supply to the myocardium. A more complete and recent version of the diagnostic criteria for the occurrence of an angina attack includes the presence of ST elevation on the ECG and in 2 out of 3

Dicrotic rise is a physiological phenomenon consisting of a periodic increase in time in the amplitude of interkinetic waves of oscillations in the tone of the flexor and extensor muscles of the animal’s limb relative to the equilibrium position. Dicrotic rises are observed in a variety of skeletal muscles under different levels of physical and neural stress. The discovery of the nature of the occurrence of dicrotic rise led to a new understanding of the mechanisms of regulation of muscle tension. In the 19th century, scientists conducted many studies to find out why these rises occur after the first contraction of the limb. It turned out that during the action of the stimulating stimulus, the muscle will first contract and then stretch. Contracting a muscle will cause other muscles that flex it to stretch. This will cause a second burst of stimulation, but the contraction will be weakened. This is why the muscle contracts more slowly and shorter, creating the effect of the dicrotic phase. The mechanism causes another tension that can increase the tension in the muscle, which can cause it to shorten. This mechanism makes muscles more resistant to fatigue, but can only be harnessed through specialized exercises. However, not all types of muscles can respond to this mechanism - it depends
