Rheobase - the lowest point on a strength duration curve at an infinitely long pulse duration Chronaxie time - the pulse width at twice the rheobase value. It approximates the most efficient stimulation pulse duration Charge (formula) - Charge= I(current) x T(time) Furman's formula - Energy(microjoules)= I(current)xV(voltage)xT(pulse width) Ohms law formula - Voltage(electromotive force)= I(current/flow of electrons) x R(resistance to current flow in ohms) Functional Refractory P...

Voltage is? The electromotive force pushing on electrons If the PM output voltage is 5v and the measured lead resistance is 330 ohms, then the current that flows out of the pacemaker into the heart is? 15.15 I=V/R=5V/.33 k ohm If a unipolar lead wire has an insulation break one would expect the resistance to? decrease for a wire fracture the resistance? increases if the output vlotage of the pacemaker is programmed from 5 volts to 2.5 volts, the energy delivered ...
