interval)
3 1st degree heart block 4 LVOT

,1.5 mV by 0.08 sec Taken on a standard ECG, measure the R wave.
1.0 mv by 0.16 sec On a standard ECG an R wave that is 1 cm high and
4 boxes wide measures:
sinus brady with ST elevation This ECG shows:
sinus rhythm with ST depression and On this ECG the sinus beat shows:
1st degree heart block
1st degree heart block This ECG shows:
Pathological Q wave (>.04 sec in The ECG changes most associated with transmural
duration or over 1/3 the height of the myocardial infarction is:
R wave)
Q wave (infarct Q waves never go An OLD myocardial infarct is seen on the ECG as a
away) significant:
, ST segment elevation In the progression of a myocardial infarction as
seen on an ECG, the first sign of acute injury to the
myocardial cells is seen as:
1. inverted T wave-ischemia When a positive ECG electrode is placed over an
2. T wave elevation/broadening- area experiencing myocardial infarction, four basic
hyperacute ischemia patterns can be seen. Match each ECG pattern in
3. Q waves- infarction the diagram with the condition of the myocardium
4. ST elevation- injury near it.
a. infarction b. injury c. ischemia d. hyperacute
iscemia
Preexcitation All the following ECG changes are associated with
CAD and myocardial infarction EXCEPT:
Q waves, heart blocks, preexcitation, ST
depression, T wave inversion
ST segment elevation Which of the following ECG changes results from
acute myocardial INJURY?
T wave inversion and ST depression Which of the following ECG changes results from
myocardial ischemia?
Pathologic Q waves
T wave inversion
ST elevation
ST depression
QTc= QT/(square root of the RR How is the standard corrected QT interval
interval) calculated? (Bazett's formula)
1. 120-200 ms Match the ECG measurements to its normal value
2. <120 ms 1. PR interval
3. <450 ms (if longer than 450 then 2. QRS duration
Long QT syndrome or hypocalcemia) 3. QTc
