Diagnostika rizika náhlé srdeční smrti založená na analýze vazby mezi krevním tlakem a tepovou frekvencí
Halámek, Josef ; Jurák, Pavel ; Kára, T. ; Nykodým, J. ; Eisenberger, M. ; Souček, M.
We tested the diagnostic contribution of parameters describing the relationship between heart rate (HR) and systolic blood pressure (SBP) on patients with cardioverterdefibrilator (ICD), patients with coronary heart disease and young and old healthy. The best diagnostic of ICD group (p<0.01) is at baroreflex sensitivity and phase variability between HR and SBP in low frequency band, if the controlled breathing 0.1 Hz is used. Both parameters are independent and should be used simultaneously
Vyhodnocení ERD/ERS: vyhodnocení latence pomocí plovoucího okna
Chládek, Jan ; Nestrašil, I. ; Jurák, Pavel ; Halámek, Josef ; Bareš, M. ; Rektor, I.
Event Related Synchronization/Desynchronization is among others characterized by amplitude and latency. Latency determination depends on the type of evaluation method and its parameters. Therefore its detection can be multiple-valued. To avoid the incorrect latency detection the analysis using smoothing floating window with different widths was employed
Rtuťový plethysmograf pro polysomnografii
Vondra, Vlastimil ; Kára, T. ; Jurák, Pavel
In this paper we present home made design and construction of multichannel amplifier for the strain gauge plethysmograph for polysomnography. The basic advantages of our design are its eight channel capacity in one device and possibility of independent supply from the battery package
Porovnání metod pro výpočet srdečního výdeje ze signálu impedanční kardiografie
Jurák, Pavel ; Halámek, Josef ; Vondra, Vlastimil ; Kára, T. ; Nykodým, J. ; Číp, Ondřej ; Eisenberger, M. ; Leinveber, P. ; Fráňa, P. ; Meluzín, J. ; Souček, M.
The goal of the study is to compare various methods of non-invasive stroke volume (SV) assessment from a raw impedance cardiography (IC) signal. IC detects changes in cardiac haemodynamic function using thoracic electrical bioimpedance technology. Corresponding changes of impedance are used along with ECG and blood pressure to measure and calculate haemodynamics parameters
