CCI CRAT Flash Cards
Heart Rate of Normal Sinus Rhythm (NSR) - answer60-100 BPM
Heart Rate of Sinus Tachycardia (ST) - answer101+ BPM
Heart Rate of Sinus Bradycardia (SB) - answer59 or less BPM
The horizontal axis on the grid paper records____________. - answertime.
How many large grid blocks on the EKG paper mark one second in time? - answerFive
(5).
How long in seconds is one large block on the EKG paper? - answer0.2 seconds (thus,
five large blocks marks 1 second in time).
The vertical axis on the grid paper records _________________. - answerEKG
Amplitude (voltage).
How many millivolts (mV) is one small block on the EKG paper? - answer0.1 mV
How many millivolts (mV) is one large block on the EKG paper? - answer0.5 mV
10 mm equals how many millivolts (mV)? - answer1.0 mV
6 mm equals how many millivolts (mV)? - answer0.6 mV
3 mm equals how many millivolts (mV)? - answer0.3 mV
5 mm equals how many millivolts (mV)? - answer0.5 mV
What is the amplitude if a complex is 22 small boxes tall, vertically? - answer2.2 mV
What is the amplitude if a complex is 14 small boxes tall, vertically? - answer1.4 mV
What is the amplitude if a complex is 7 small boxes tall, vertically? - answer0.7 mV
How many seconds does one small box horizontally represent? - answer0.04 seconds
(thus 5 small boxes horizontally, equals 0.20 seconds (one large box)).
, What is the normal/typical speed of EKG paper? - answer25 mm/second
Name the lettered components of a normal heartbeat found on an EKG? - answerP, Q,
R, S, T, U
What is a P-wave and what does it represent in a heart beat? - answerThe first
deflection.
Normally positive (upward) waveform.
Indicates atrial depolarization.
What follows a p-wave on an EKG tracing? - answerA QRS Complex.
What does a QRS complex represent? - answerVentricular Depolarization
What is a t-wave and what does it represent in a heart beat? - answerA "normally"
modest positive (upward) waveform.
Indicates ventricular repolarization.
What is a U-wave? - answerFollows the t-wave.
Represents recovery of the Purkinje fibers.
Important: May not be observable on an EKG tracing.
The "Zoll Way" to assist with Rhythm interpretation (REMEMBER TO HELP WITH
INTERPRETATION ON THE EXAM): - answerRhythm
Rate
P Wave
PR Interval
QRS Interval
T Wave
