RA negative
In lead I RA is __________, LA is
LA positive
__________
RA negative
In lead II: RA is _________, and LL
LL positive
_________.
LA negative
In lead III: LA _______ and LL _______. LL positive.
0.04
Each mm between vertical lines on ECG
paper represents ____ seconds
CK elevation will be detected with CVA
LD1 > LD2
After MI, the following LDH isoenzymes
can be expected
PT or INR
Oral anticoagulation dosing is determined
by assessing the
The normal PR interval measures 0.12 to 0.20 seconds
first negative deflection
The Q wave is the first ____ of a
ventricular complex
count the # of QRSs in a 6 second strip, and x 10
The spaces/boxes between QRS complexes vary throughout the irregular rhythm
strip. If there are 4 large boxes between the first QRSs, the HR is 75 (300/4=75). If
there are large 2 boxes between the next two QRSs, the rate is 150 (300/2=150).
How to calculate an irregular ventricular Then, if there are 3 large boxes between the next QRSs, the rate is 100
rate (300/3=100). So each calculation is different with an irregular rate and the 'overall'
heart rate is not accurate.
ventricular depolarization and repolarization to occur
The QT interval represents the time frame

In lead III LA is negative, LL is positive
2.5-3.5
The target INR range for patients with
mechanical prosthetic heart valves is
The cardiac cycle includes the PQRST
An MI can be safely diagnosed with the is specific to cardiac tissue
CK-MB result because this isoenzyme
Cholesterol is carried on LDL
a positive deflection
An impulse travelling toward the area
where a positive electrode is placed is
recorded as
Torsades de Pointes can result from long QT intervals
LL
Most of the heart's electrical forces are aimed downward and toward the left (toward
Normally, the majority of cardiac electrical the LL electrode) because this direction is toward the LV which is the largest and
activity travels to the electrode placed on hardest-working chamber (so it needs the most electrical force to depolarize).

The P wave represents atrial depolarization
LDH
Which enzyme should be assessed when
the presenting patient indicates that s/he
had MI symptoms 5-6 days ago?
Prior to obtaining lipid studies patients must be fasting
