Physiology and Pathophysiology
The teaching material Electrocardiography (ECG) describes an origin and propagation of the electric signal in the heart, ECG registration and analysis.
The teaching material consists of two thematic groups: Evoked cortical potentials and Electroencephalography (EEG). The part dedicated to EEG clarifies origin of EEG signal, registration methods, EEG rhythms and EEG use.
Teaching video demonstrates determination of plasma volume by means of Evans blue dye and the effect of intravenous injection of hypertonic glucose solution on plasma volume in rat.
Teaching video shows the negative chronotropic effect of vagus nerve in rat heart.
The spontaneous production of impulses in the heart is demonstrated with help of the Langendorff apparatus. In isolated, retrogradely perfused heart the spontaneous rhythmical activity is maintained.The spontaneous production of impulses in the heart is demonstrated with help of the Langendorff apparatus. In isolated
This teaching material consists of a text part (see below) and an animation. The text part contains the detailed description of the individual phases of the cardiac cycle. The animation shows the mechanical events in the heart during the cardiac cycle including the arterial pulse, electrocardiogram, heart sounds, venous pulse, pressure and volume changes in the right atrium and in the left ventricle.
