Short-term variability of blood pressure: physiology and pharmacology

Abstract

Non invasive continuous measurement of blood pressure (BP) is currently performed at the finger level. The various oscillations of BP are distinguished using spectral analysis based on the fast Fourier transform. The first order oscillation of BP is synchronous with the heart beat and generates pulsaltile changes in BP. Second order oscillations are generated by respiration and depend on intrathoracic pressure changes. They do not exceed few millimeters of mercury. Heart rate also oscillates with respiration. This respiratory sinus arrhythmia depends on vagal activity. A slower third order oscillation also called 10-s period rhythm or Mayer waves depend on vascular tone changes. These waves may reach 20 mmHg. Mayer waves reflect oscillations in resistance vessels and depend on sympathetic discharges. Sympathetic nerves determine oscillations in resistance vessels and cardiac rhythm at the same 0.1 Hz frequency. A better understanding of these oscillations helps in understanding BP regulatory mechanisms and in treating BP disorders. Prognosis of arterial hypertension also depends on these BP fluctuations. Recent time and frequency domain developments in the analysis of the reflex relationship between BP and heart rate allow the ...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
