The presentation deals with active electric biosignals originating from the electric activity of the heart and with different possibilities of their registration and analysis. Suitable to all study branches.
The lecture deals with active electric biosignals originating from the electric activity of the skeletal muscles, brain, stomach, and eyes, and with possibilities of their registration and analysis. Suitable to all study branches.
The lecture „Basic elements of electric circuits“ is aimed to explain basic terms, quantities and units It contains basic electrical values like electric current, electric resistance next measurement of electrical quantities and elements of electric circuit.
The lecture „Passive electrical properties of tissues“ is aimed to explain basic terms, quantities and units necessary to understand electrical properties of biological tissues. It contains physiological values of individual quantities for some tissues and organs, electrical model of these properties, describes effect of electric current on tissues and its use in diagnostics and therapy. The lecture also includes safe values of electric current and rules for event of injury by electric current.

Femtosecond laser uses an infrared beam of light to precisely separate tissue through a process called photodisruption by generating pulses as short as one-quadrillionth of a second. It has wavelength of 1053 nm and is based on the technology whereby focused laser pulses divide material at the molecular level without transfer of heat or impact to the surrounding tissue.
