Abstract
Hypertonia (from the Greek word hyper means high, high tone means tension) is an increase in the tone (tension) of organs and tissues relative to the norm. It is a pathological process in the neuro-functional state of central and peripheral blood vessels. An increase in blood pressure caused by an increase in the tone of small-caliber arteries is called hypertension. A hypertensive crisis occurs when the compensatory mechanisms are not able to reduce the increased blood pressure to improve the condition of the body. In this case, the increase in blood pressure is accompanied by severe anxiety, severe pain in the head and heart, nausea, vomiting, and other clinical symptoms. A hypertensive crisis is always a threat to people's lives, and failure to provide high-quality rapid intensive therapy can lead to the above-mentioned complications.
