2. For an ideal square-wave defibrillator, determine the energy delivered to the patient (see Figure 8-11).
3. Given a situation when a fully charged defibrillator capacitor discharges through the chest, determine the current (peak) through the thorax and the voltage drop (peak) across the thorax.
7. Calculate the energy delivered by each pulse from a pacemaker from the given pulse signal as shown
9. Calculate the battery life in years when the pacemaker has the following characteristics: Battery ampere-hours (Ah) = 1.2*; pulse voltage = 2 V; *pulse width = 1 msec*; pulse time period = 1 sec; *electrode-heart resistance = 150 ohms; current drain on the battery = 1.3 µA.
