EZ ECG

1. The EKG of a patient with hypokalemia will likely show the following characteristic

Absence of a P wave
Presence of a large P wave
Absence of QRS wave
Flattened T wave


2. The EKG of a patient with hypokalemia will likely show the following characteristic

Elevation of the ST segment
Presence of a prominent U wave
Presence of a prominent T wave
NO specific characteristic


3. First degree block is charcterized by the following ECG finding

More than one P wave for every QRS wave
A ratio P /QRS wave greater than 1
A ratio of P/QRS wave smaller than 1
A prolonged PR interval


4. No P wave means

No atrial contraction
No ventricular contraction
Fibrillation of the ventricles
No contraction on the left atrium


5. The following EKG finding indicates a serious emergency. Death is imminent

No P wave
Prominent U wave
Prolonged PR interval
No QRS wave


6. A complete dissociation between the P wave and the QRS wave indicates

First degree AV block
Second degree AV block
Third degree AV block
Cardiac arrest


7. Clot formation in the atria is more likely a serious complication of

First degree AV block
Second degree AV block
Third degree AV block
Atrial fibrillation


8. Contraction of the ventricles corresponds to

P wave
QRS wave
T wave
U wave


9. A second degree block is characterized by the following EKG finding

Ratio P / QRS > 1
More P waves than QRS waves
The SA node fires more than once before stimulating the AV node
All of the above


10. An elevation of the ST segment is characteristic of

Hypokalemia
Hypernatremia
Hypothyroidism
Myocardial infarction
