Physiology of continuous-flow pumps.
The use of mechanical pumps for circulatory support started in the mid-1950s. The evolution of these devices has led to the present-day use of continuous-flow pumps to take over the function of a patient's failing heart. The physiology associated with rotary blood pump use is quite d...
[Study of traditional Chinese medicine pulse signals in patients with coronary heart disease based on recurrence quantification analysis].
By using recurrence quantification analysis (RQA) to analyze traditional Chinese medicine pulse signals of patients with coronary heart disease (CHD), this study aims to find nonlinear dynamic parameters of pulses to distinguish patients with CHD from normal subjects....
Usefulness of peripheral vascular function to predict functional health status in patients with Fontan circulation.
We sought to assess the association between peripheral vascular function and functional health status in Fontan-palliated patients. Asymptomatic Fontan patients (n = 51) and age- and gender-matched healthy controls (n = 22) underwent endothelial pulse amplitude testing using a noninvasive fingertip...
Heartbeat classification using feature selection driven by database generalization criteria.
We studied and validated a simple heartbeat classifier based on ECG feature models selected with the focus on an improved generalization capability. We considered features from the RR series, as well as features computed from the ECG samples and different scales of the wavelet transform, at both ava...
[Estimating cardiac output. Utility in the clinical practice. Available invasive and non-invasive monitoring].
We also want to establish the clinical situations in which the measurement of cardiac output can add valuable information for the management of critically ill patients. The Fick technique, used in the beginning to calculate cardiac output, has been replaced today by thermodilution techniques (transc...
[Individual specificities and heart rhythm variability under emotional influence in women of various age].
The autonomic regulation of heart rhythm against the background of emotiogenic factors in women aged 30-60 was studied. A method of variational pulsemetry based on the analysis of heart rhythm variability (HRV - temporal and spectral) was used for physiological control of the status...

[Pulse. "Do you feel?" Boom, boom, a beating heart, a propagating wave... what does pulse tell us?].
Evaluation of haemodynamic changes in hypertensive patients during tooth extraction under local anaesthesia.
This study was conducted to determine the changes in blood pressure and the pulse rate of patients with controlled hypertension having dental extraction under local anaesthesia utilizing 2% lignocaine with adrenaline, and to evaluate whether these changes in blood pressure were are attributable to ad...
