Quiz :Trans telephonic Monitoring - Answer :Transmitted over phone to a
LICENSED practitioner to read (magnetic tape), Patients use up to 30 days
Quiz :Digital Monitoring - Answer :Transmitted over a computer where report
is verified by a licensed practitioner
Quiz :Telemedicine monitoring is usually used to evaluate_____________ -
Answer :Artificial Pacemaker Functioning
Quiz :Ambulatory Monitor - Answer :Most common type is holter monitor
(continuous or intermittent-only records when patient has symptoms. Used for
dysrhythmias, evaluation cardic meds, and checking pacemakers-24-48 hrs-up
to 30 days
Quiz :Procedure for applying ambulatory monitor (holter) - Answer :Educate
patient, equipment gathered and prepared, electrodes placed on chest,
equipment hooked up
Quiz :Procedure for removing - Answer :before removing, diary must be
complete by patient, then turn off recording, remove electrodes, clean skin,
report results
*process is based on type of equipment uses
Quiz :Functions of common ECG machine - Answer :3 basic functions are
input, signal processing, output display. Sensors in ECG machine serve as
receiving devices for the electrical activity of the heart.
INPUT-Electrode placed on patients skin direct impulses to ECG instrument,
providing the input. Signal processing happens in ECG machine, output display
is the result of processing and is shown on screen (known as oscilloscope)
and/or on ECG tracings. Electronic output is quickly becoming most common
choice for ECG tracings.
Quiz :ECG machine controls - Answer :# most common are speed, gain,
artifact filter.
also have these controls: LCD display, heart rate limits, standardization, and
lead section
, Quiz :Speed control - Answer :regulates how fast or slow the paper or data
run during procedure. MOST COMMONLY USED: 25 mm/sec
*increasing the speed for example to 50mm/sec will make wave forms appear
wider and is useful if patient heart rate is very fast. if you change the speed
you must note on tracing by circling the setting on tracing and notify the
healthcare provider
*speed in measure on a horizontial axis
Quiz :Gain - Answer :control on ECG machine that increases or decreases size
of ECG tracing. Normal setting is 10mm/mV. 20mm/V will double size and
5mm/V will reduce size by half
* NEED TO KNOW mV is a millivolt-unit of measurement to indicate voltage-
Voltage is measures on a vertical axis
Quiz :Artifact Filter - Answer :unwanted marks on ECG tracing caused by
something other than heart activity
*Normal settings is between 40-150Hz, 40 Hz can be used to reduce artifact
Quiz :3 most common causes of artifact are: - Answer :Somatic tremor,
wandering baseline, and AC interference
Quiz :History of ECG - Answer :1903-Wilhelm Einthoven
Quiz :ECG graph paper - Answer :Boxes are 5mm by 5mm and indicate .04
seconds in time horizontally and .1 mV in voltage vertically
Quiz :How many seconds are between 3 tick marks on top of ecg paper? -
Answer :6 seconds
Quiz :EGC PAPER provides measurement for both______ - Answer :time and
voltage.
smallest box =.04 second in time and 1mm or .1mV in voltage
2 large boxes =10mm, which equals 1cm for vertical measurement.
Quiz :ECG machines must be calibrated - Answer :so that 1cm=1mV
Quiz :Center for disease control & Prevention has 2 levels of precautions
which are_________ - Answer :1. Standard-Hand Hygiene/gloves for
blood/body fluids, non-intact skin, and mucous membranes. For standard wash
hands and use gloves
