- Measure of the QT-RR dynamic coupling in patients with the long QT syndromeJosef Halamek
Institute of Scientific Instruments, AS CR, Brno, Czech Republic
Ann Noninvasive Electrocardiol 17:323-30. 2012..The patients with the long QT syndrome type-1 (LQT-1) have an impaired adaptation of the QT interval to heart rate changes. Yet, the description of the dynamic QT-RR coupling in genotyped LQT-1 has never been thoroughly investigated...

Institute of Scientific Instruments, Academy of Sciences, Czech Republic, Kralovopolska 147, 612 64 Brno, Czech Republic
Conf Proc IEEE Eng Med Biol Soc 2011:961-4. 2011..Conclusion: The use of heart rate excitation and all measurements conditions should be defined for the exact analysis of the repolarization dynamic parameters...
- Variability of phase shift between blood pressure and heart rate fluctuations: a marker of short-term circulation controlJosef Halamek
Institute of Scientific Instruments, Academy of Sciences, Kralovopolska 147, 612 64 Brno, Czech Republic
Circulation 108:292-7. 2003..We postulated that the variability of the phase shift between blood pressure and heart rate fluctuation near the frequency of 0.10 Hz might be useful in assessing autonomic circulatory control...

Epilepsy Res 90:28-32. 2010..Our study demonstrates a capacity of interictal HFO to detect the SOZ in focal cortical dysplasias...
- The effect of short-term isometric muscle contraction and the Valsalva maneuver on systemic and pulmonary hemodynamics in patients with severe heart failureMiroslav Soucek
Second Department of Internal Medicine, St Anne s University Hospital, Brno, Czech Republic
Clin Cardiol 32:E32-9. 2009..Patients with severe heart failure are often in very poor physical condition, they are unable to take part in the usual exercise programs, and therefore need an individual approach...
- On the time course of synchronization patterns of neuronal discharges in the human brain during cognitive tasksMilan Brazdil

PLoS ONE 8:e63293. 2013..In particular, an initial global reorganization in the delta and theta bands (2-8 Hz) is followed by gamma (20-95 Hz) and then beta band (12-20 Hz) synchrony...
- Cardiac output measurement in patients with an implanted pacemakerVlastimil Vondra
Institute of Scientific Instruments, Academy of Sciences of the Czech Republic, Kralovopolska 147, 612 64 Brno, Czech Republic
Conf Proc IEEE Eng Med Biol Soc 2007:916-8. 2007..We have scored the maximum relative cardiac output for each patient. For the measurement we have used a home made digital bioimpedance monitor for impedance cardiography. The result of 26 patients is presented in this study...
