(EKG). Questions with Correct Verified
Answers Newest 2026-2027. Graded A
Atrial Pacing - ANS Abnormal P wave (Atrial Capture) before the P wave
AV Sequential Pacing - ANSSpike (Atrial Capture) before P wave and a
Spike (Ventricular Capture) before Wide QRS
Most common type of pacemaker used
How do you count heart rate when looking at an EKG? - ANS300, 150,
100, 75, 60, 50, 43, 38 - going down the big blocks between R wave peaks
Know it has to be a regular rhythm in order to calculate HR in this fashion
How do you determine if a heart has RAD or LAD (axis deviations)? -
ANSLook at direction of QRS Complex deflections in leads I and aVF
Up in I and Up in = Normal Axis
Up in I and Down in aVF = LAD
Down in I and Up in aVF = RAD
1
,Down in I and Down in aVF = Extreme RAD
Know you see LAD with MI and Hypertrophy of the Atria
LAD in picture
How would you diagnose a Myocardial Infarction? - ANSEKG, Cardiac
Biomarkers (Troponin), Pt. History
How would you go about diagnosing someone with Ischemia/Angina
Pectoris? - ANSHave to do a stress test to elicit ST Depressions
How would you treat Sinus Bradycardia? What are the requirements for
Sinus Bradycardia? - ANSTreatment -
-Atropine
-Transcutaneous Pacing (TCP) - Electrodes placed through
Requirement -
-HR less than 60 bpm
-Can be normal rhythm
Know that Sinus Bradycardia is the mot common rhythm disturbance seen
in early stages of an AMI
How would you treat Sinus Tachycardia? What are the requirements for
Sinus Tachycardia? - ANSTreatment -
2
, -Treat cause first
-Unstable Pt. = Cardioversion/Electricity
-Stable Pt. = Vagal maneuvers (holding breath and clenching - stimulates
the Vagus Nerve), Adenosine
Requirement -
-HR greater than 100
-Can be normal rhythm
If someone had an old MI, what would you find on EKG? - ANSStill see Q
waves in infarcted area
Know that ST segments and T waves go back to normal in days after
infarction
In what leads on the EKG would you find evidence of an MI in the Anterior
wall of the heart? - ANSI, V1, V2, V3, V4
In what leads on the EKG would you find evidence of an MI in the
Inferolateral wall of the heart? - ANSII, III, aVF - Inferior portion of the heart
I, aVL, V5, V6 - Lateral portion of the heart
Know that Hypertrophy means Ventricles and Enlargement means Atria
Also know know that all of these must be verified with an Echocardiogram -
ANS
