discharge buttons into the analyzer. Read the time for charging the defibrillator on the

analyzer’s display “Chg Time: xxx.x sec”. Compare the value with the data stated by the

manufacturer in the user manual [3.8, 3.9].

Ad task 3)

Connect the patient cable in the connector for the ECG input on the defibrillator, and

its second end to the simulated electrodes in the upper part of the analyzer’s front side via

press studs. Then proceed according to the instructions in the user manual for the defibrillator

analyser. Watch all the available ECG courses, including arrhythmias.

Follow the instructions in the user manual for the defibrillator [3.8, 3.9] to set up the

defibrillator into the synchronized mode and perform a synchronized cardioversion according

to the procedure from section 1). On the analyzer’s display read and record the energy of the

applied discharge - “Energy”, the peak voltage value - “Peak V”, the peak current value -

“Peak I”, and the length of the defibrillation pulse. Use the push button “Playback last pulse”

to switch over to the defibrillation pulse’s time course chart and draw its shape.

Ad task 4)

Connect the cables for transcutaneous stimulation to the defibrillator. By means of a

edutool “Converter for pacing” in Fig. 3.9 connect the defibrillator’s stimulation cables to the

oscilloscope. The edutool is a power voltage divider with resistors R

= 52 Ω and R

= 7 Ω,

which means the voltage ratio on the output is 0.12.

Switch the defibrillator over to the stimulation mode “Pacemaker Stimulation”

(“KStim”)!! Set different values of the stimulation current on the defibrillator, within the

entire range of values 0-200 mA (for at least 5 values), and on the oscilloscope, read the pulse

parameters, the pulse width, peak voltage value, repetition frequency of the pulses, and draw

their courses. Do not forget to recalculate the read voltage on the oscilloscope via the ratio on

the divider. Calculate the stimulation pulse’s energy from the value of the set current and the

measured voltage.

Select one value of the stimulation current and verify the conformity of the pulse

parameters for different repetitive pulse frequencies set up on the defibrillator (for at least 3

frequencies).
