CCDS IBHRE Exam With 100% CorrectAnswers 2023Rheobase-Correct Answer-the lowest point on a strength duration curve at an infinitelylong pulse durationChronaxie time-Correct Answer-the pulse width at twice the rheobasevalue. Itapproximates the most efficient stimulation pulse durationCharge (formula)-Correct Answer-Charge= I(current) x T(time)Furman's formula-Correct Answer-Energy(microjoules)= I(current)xV(voltage)xT(pulsewidth)Ohms law formula-Correct Answer-Voltage(electromotive force)= I(current/flow ofelectrons) x R(resistance to current flow in ohms)Functional Refractory Period-Correct Answer-the coupling interval which first results ina measurable degree of delay in impulse conductionEffective Refractory Period-Correct Answer-the longest coupling interval to beassociated with blockDevices with NO interaction with pacers-Correct Answer-1. microwave oven, 2. CTscan/Ultrasound 3. X-rays (diagnostic)Devices that cause transient or 1 beat inhibition-Correct Answer-1. EAS 2. Cellphones3. Arc Welding 4. airport metal detector 5. TENS 6. Electric appliances such as electricblanket & power toolsDevices that may damage the pacemaker-Correct Answer-1. MRI 2. Defibrillator 3.Cardioversion 4. Cautery/RF Ablation 5. Radiation TherapyResistance in Series-Correct Answer-Series means the beginning of one resistance isconnected to anotherSum the resistances: R1+R2= total resistance. EX: A LEAD FRACTURE (fracturesINCREASE impedance)Resistance in Parallel-Correct Answer-Parallel means all the resistances areconnected to the same point.(R1xR2)/(R1+R2)= total resistance
