Cardiotachometer
Máca, Kamil ; Číž, Radim (referee) ; Chmelař, Milan (advisor)
This masters thesis describes possibilities of a heart rate measuring. Several methods of measuring will be discussed. The primary objective of this paper is to design battery powered cardiotachometr with a range of 30-240 beats/min and a low battery indication. Cardiotachometer uses the R waves detector to measure heart rate. This thesis is focused on creation of the block diagram, electrical circuit, printed circuit and calculation of electronic device used in cardiotachometers.

Cardiotachometer
Čech, Jakub ; Sekora, Jiří (referee) ; Čech, Petr (advisor)
Master’s thesis deals with theme of heartbeats. Monitoring and evaluation of heartbeat is important for diagnostician cardiac dysfunction. First part of thesis is focused on anatomical description of heart and his operation. Another part is description of electrical activity of the heart and methods of capture. There is also mention of the cardiac rhythm and its disorders. One of the principal objective of this thesis is to study methods for sensing heart rate. These methods are analyzed and then selected a particular method for further solutions. The core thesis is to design functional cardiotachometer. Cardiotachometer derives the heart rate signal from phonocardiographical signal, which is acoustic manifestation of heart. Implementation takes place in the Labview, which is graphical programming environment. Suggested the device measures the current and average heart rate and the addition of HRV analysis in time domain.
