EKG EXAM #1 QUESTIONS AND
ANSWERS
Which heart rhythm is characterized by the following:

P waves and QRS are firing on their own (they are disassociated)
Slow ventricular rate. - Answer-3rd degree heart block

Normal PR interval? - Answer-0.12-0.20

Normal QRS? - Answer-0.04-0.12

This heart rhythm changes with inspiration - Answer-Sinus arrhythmia

Rhythm characterized by a sawtooth pattern on EKG - Answer-Atrial flutter

Any rate that is > 150 = - Answer-Supraventricular tachycardia (SVT)

When does PVC become pathologic? - Answer-When there are more than 6/minute

Which heart rhythm is characterized by the following:

Normal sinus rhythm that pauses for a little and then resumes back to normal sinus
rhythm - Answer-Sinus pause

How many PVC's in a row make ventricular tachycardia? - Answer-3 in a row = V tach

What is the difference between ventricular tachycardia and supraventricular
tachycardia? - Answer-The difference is in how wide the QRS is

In SVT, the QRS complex is shorter (< 0.4)
In VT, it is a little wider

QRS greater than 0.12 is characteristic of: - Answer-Bundle branch block

What suggests the diagnosis of SVT rather than V tach? - Answer-SVT has a QRS <
0.14 (it would have a more narrow QRS than VT)

What is the difference between Torsades and ventricular fibrillation? - Answer-Torsades
is more marked than ventriuclar fibrillation

1st degree AV block is characterized by: - Answer-PR interval greater than 0.2

Ion responsible for SA and AV node depolarization - Answer-Calcium

, Ion that initiates myocyte depolarization - Answer-Sodium

An early beat with no P wave is: - Answer-Premature junctional beat

What is the rate for sinus tachycardia? - Answer-100-150

What is the difference between atrial fibrillation and atrial flutter? - Answer-In A fib - no
distinct P waves, QRS = irregularly spaced

The capacity of a single cell to generate action potential sponatneously - Answer-
Automaticity

Right bundle branch block looks like: - Answer-Bunny ears

Left bundle branch block looks like: - Answer-Swoop

What does the QT interval stand for? - Answer-Ventricular depolarization and
repolarization

What is the rate for the AV node? - Answer-40-60

A widened QRS beat is indicative of: - Answer-PVC/PVB

Which coronary artery supplies the AV node? - Answer-Right coronary artery

What is the commonly used lead that we interpret everything from? - Answer-Lead 2

Interior of all cells are _________________ charged

After depolarization, they become ________________ charged - Answer-Negatively
charged
Positively charged

Ion that has an "inward" gradient and ion that has an "outward" gradient - Answer-
Inward - Na
Outward - K

Ion responsible for cell-cell conduction of depolarization through the myocardium -
Answer-Na

Ion responsible for myocardial contraction - Answer-Ca

Ion responsible for repolarization and maintenance of the baseline potential - Answer-K
