What are the three types of leads in a 3-lead EKG?
Answer- Leads I, II, and III, which are bipolar leads.
What are augmented leads in EKG?
Answer- Augmented leads include AVR, AVF, and AVL, providing
additional views of the heart.
What is the purpose of a 12 Lead EKG?
Answer- It encompasses all views of the heart to identify ischemia or
electrical conduction issues.
What does the P wave represent in an EKG?
Answer- Atrial depolarization (contraction).
,What does the QRS complex represent in an EKG?
Answer- Ventricular depolarization.
What does the T wave represent in an EKG?
Answer- Ventricular repolarization (resting phase).
What is the normal PR Interval range?
Answer- 0.12 - 0.20 seconds.
What could a QRS duration greater than 0.11 seconds indicate?
Answer- It could indicate a bundle branch block.
How is the atrial rate determined on an EKG?
Answer- By the frequency of the P-waves.
What should the atrial and ventricular rates indicate in a normal patient?
Answer- The atrial and ventricular rates should be the same.
,What does each small box on EKG paper represent in time?
Answer- 0.04 seconds.
How do you calculate heart rate for a regular rhythm?
Answer- Count the number of QRS complexes in a 6-second strip and
multiply by 10.
What is ST Elevation and why is it important?
Answer- ST Elevation is a life-threatening condition that requires
medical attention, indicated by the ST segment being above the baseline.
What does NSTEMI indicate?
Answer- NSTEMI is indicated by ST depression, which is also life-
threatening.
What defines a Q wave MI?
Answer- A Q wave is considered significant if it is 2mm deep and at
least 0.04 seconds in duration.
, When should a Rapid Response be called?
Answer- In cases of unstable vital signs, seizures, or other critical
situations.
What does PEA stand for in cardiac terms?
Answer- Pulseless Electrical Activity.
What are the three layers of the heart?
Answer- Epicardium (outermost), Myocardium (middle), and
Endocardium (innermost).
What does a Sub endocardial MI indicate?
Answer- It indicates that the myocardial infarction has not yet penetrated
through the endocardium.
What EKG rhythms are excluded from PEA?
Answer- Ventricular tachycardia (v-tach) and ventricular fibrillation (v-
fib).
