IBHRE STUDY GUIDE EQUATIONSCardiac output (CO) - ANSWER = Heart rate (HR) * stroke volume (SV)
Ejection Fraction (EF) - ANSWER = (EDV - ESV)/EDV
Ejection fraction (EF) - ANSWER = SV/EDV
Voltage (V) - Answer = Current (I) * Resistance (R).
Capacitance (C) [Farads]. - ANSWER = Charge (Q)/Voltage (V)
Battery Longevity (T) [In years] - Answer = Charge (Q) / Current (I) * 114.
Battery Longevity (T) [In years] - ANSWER = Battery Capacity [Amp*hours] /
Current Drain (I) [Amps] / Hours per Year
Energy (E) [joules] - ANSWER: V * I * time (t) [ms]
Energy (E) [joules] - Answer = (V^2 / R) * t.
Lower Rate Limit (or Base Rate) - ANSWER = Paced AV Delay + VA Interval.
Total Atrial Refractory Period (TARP) - Answer = Sensed AV Delay +
PVARP.
Wenckebach interval - ANSWER = UTR (aka MTR) - TARP [in milliseconds]
Total Atrial Refractory Period (TARP) - Answer = Point at which you receive a
2:1 block.
Resistance in Parallel (R) - ANSWER = (R1 * R2)/(R1 + R2)
Minute ventilation = tidal volume x respiratory rate.
Stored Capacitor Energy = 0.5 * C * V^2.
