title: [Baroreflex sensitivity: measurement and clinical aspects].
abstract: Homeostasis of blood pressure is indispensable for proper functioning of the body. Sympathetic and parasympathetic part of the autonomic nervous system (ANS), acting on the principle of negative feedback, ensure fast and efficient regulation of blood pressure. A key element in this process is the arterial baroreceptor reflex (BR). Disorders of BR play a significant role in the development and progression of many diseases of the cardiovascular system. Baroreflex sensitivity (BRS) and heart rate turbulence (HRT) are indicators of ANS function. Many clinical trials confirmed the value of ANS function assessment in risk stratification of patients with diseases such as hypertension, coronary artery disease, congestive heart failure, diabetes and stroke. Neither BRS nor HRT can be assessed in patients with atrial fibrillation and flutter, sino-atrial and atrioventricular blocks or in patients with pacemakers. Analysis of these indicators is therefore limited to a group of patients in sinus rhythm.
