TEST
E = V x I x Time - ANSWER Formula for Energy
ANSWER: Ampere measures the electron flow rate or current in an electrical
conductor, measured in Coulombs per second.
Ampere-hour (Ah) is a unit of battery capacity that represents the amount of
energy charged in the battery.
Capacitance: ANSWER Relationship between stored charge and applied voltage
E = 0.5 x capacitance x voltage ^2 - Stored energy equation.
Power - ANSWER The rate at which energy is provided or absorbed
Tesla - the unit of magnetic flux density.
Magnetic field is formed when electric charge carriers move through space or
within an electrical conductor.
Slew rate is the change of voltage over time.
Deg F equals 9/5 x deg. C + 32 - Answer Temperature conversion: Celsius to
Fahrenheit
0 degrees K = -273 degrees Celsius - ANSWER What is 0 K in Celsius?
P = Energy / Time - Equation for Power
Platinum - Answer Signals are sent through ___ electrodes to the recording
system.
, ANSWER: 0.5-30 Hz High pass filter for EKG and intracardiacs.
ANSWER: 100–400 Hz Low pass filter for EKG and intracardiacs.
Wheatstone Bridge - A resistor/transducer that monitors pressure changes in the
cardiovascular system.
ANSWER: Anachrotic notch When the aortic valve opens, it can be seen on the
pressure waveform.
Dichrotic notch - answer When the aortic valve closes, this can be seen on the
pressure waveform of the valve.
Capacitors - DC defibrillators store electrical energy from charge in _____.
Hand to Hand - ANSWER In electrical harm, the path of current that is most
likely to be lethal is ___
Relative - ANSWER During the refractory period, a PVC might produce
VT/VF.
ANSWER: Increases the slope of Phase 4 Sympathetic nerve stimulation
increases cardiac action potential, which speeds up heart rate.
Potassium - Answer What ions leak out of the cardiac cell during systole?
Calcium - Answer Depolarization of the sinus node is caused by ___
Early Afterdepolarization - ANSWER depolarization that happens during the
early end of Phase 2 or early Phase 3 can lead to polymorphic VT or torsades.
Delayed Afterdepolarization - ANSWER depolarization that happens during
late Phase 3/early Phase 4 might cause RVOT VT.
Cocci are spherical bacteria.
Bacilli are rod-shaped microorganisms.
