What are the five steps in reading an EKG? |
-Are P waves present? How many? -Are P waves regular - Are R waves regular - How many R waves in 60 secs? - What is the length of the PR interval and width of QRS complex |
|
|
What is the Normal PR interval? |
0.12- 0.20 |
|
|
What does it mean if PR interval is longer than .20? |
Interval is prolonged and there is a block. Which means slow conduction through AV nodes, this can be caused by drugs |
|
|
What is V-tach? And how is it presented (how many beats per min)? |
Ventricular tachycardia 100- 250 beats per min |
|
|
Is there a plus present in stable V-tach and how is this treated? |
Yes pulse is present and it is treated with Amiodarone |

|
What is PVC |

|
|
What meds would you use to treat a patient who presents with frequent PVCs? |
Lidocaine (Xylocaine, Lidoderm) |
|
|
In a nun urgent situation where a patient presents with irregular pulse what should the nurse do first? |
ASSESS!!! Ask patient if this is normal for them |
|
|
Patient presents with unstable V-tach you assess and pulse is missing what is the next intervention? |
Defibrillate!!! |
|
|
What is Defib? |
Defib- implanted beneath the skin and automatically send shocks to the heart when it becomes tachy to restore a regular rhythm |
|
|
What is cardioversion? |
Cardioversion is synchronized with EKG and it shocks on R waves (Depolarization) to restore normal rhythm |
|
|
Will a patient undergoing cardioversion be awake? |
NO patient requires sedation |
|
|
What is angina? |
Intermittent blood flow to the heart that leads to chest pain |
|
|
Patient complains of chest pain what is the treatment of choice? |

|
|
How is A-Fib presented on an EKG? |
-No P waves -Irregular R waves -F waves are present |
|
|
A patient presents with AFib how would you know if this patient rate is controlled or uncontrolled? |
-Controlled rate is 100 or less -Uncontrolled rate is above 100 could be up to 150 |
|
|
How is a patient with uncontrolled AFib treated |
With adenosine and this must be given fast via IV push |
