ARRHYTHMIA DIAGNOSIS AND TREATMENT
STRATEGIES OVERVIEW
◉ what is the term used to denote the total opposition to flow of
alternating current in a circuit
Answer: impedance
◉ what is the most common DC electric power source
Answer: battery
◉ electric battery has a frequency of
Answer: 0Hz
◉ the elimination of vibrations at certain frequencies is
accomplished through the use of electronic devices known as
Answer: filters
◉ when a DC defibrillator "charges" it stores energy in its
Answer: capacitors
,◉ EP lab external defibrillators should be tested by
Answer: discharging paddles into a dummy load
◉ the watt second (or joule) is a unit of
Answer: energy
◉ what is the current drawn by a resistor of 100ohms if a 10 volt
battery is applied across it
Answer: 0.1amp
I = V/R
◉ using ohms law calculate the amount of current drawn by a
pacemaker if its lead resistance is 200ohm and the pacing vorlage is
1 volt
Answer: 5mA
I = V/R
I = 1000Mv / 200 ohm
◉ in an electrical injury the pathway of current most likely to be
fatal is
Answer: hand to hand
, ◉ for maximum electrical safety the ECG monitored patient should
be ___ and the monitor chassis should be ___ or nonconductive
Answer: ungrounded, grounded
◉ in the ICU when recording an intracardiac ECG from a pacing
electrode or a pericardiocentesis needle in the heart it is safest to
Answer: use a battery powered monitor
◉ when you plug in an electric instrument you are alarmed when
sparks fly from the wall outlet. the most likely electrical safety
problem is a
Answer: machine off-on swtich was left turned on
◉ the prefix centi corresponds to
Answer: 1/100
◉ which prefix is correctly arranged from smallest to largest
Answer: nano, micro, milli, centi
◉ convert 30kg into pounds
Answer: 66
◉ 100 degrees fahrenheit equals
