Summary

Head-up tilt table testing is used for diagnostics of vasovagal syncope. Beat-to-beat blood pressure recording and ECG monitoring is not sufficient for clarification of the syncope mechanisms in individual patients however. That is why a Force Task Monitor was developed in Graz, Austria. In addition this device enables stroke volume by impedance Method recording. Other advantages are calculations of cardiac output, beat-to-beat total peripheral resistance, heart rate variability and baroreflex sensitivity as well as activity of sympathicus and parasympathicus assessment. These methods enable detailed hemodynamic analysis during the whole head-up tilt testing duration, the moment of syncope including.

Key words:
vasovagal syncope - head-up tilt table testing - Task Force Monitor - heart rate variability - baroreflex sensitivit
