Which of the following leads would help to record the electrical activity in the heart's
horizontal plane?
-Bipolar lead
-12-lead ECG
-Precordial leads
-Unipolar leads ANS: Precordial leads
This provides a transverse view through the middle of the heart which divides it into upper
and lower portions.
Of the electrocardiogram waves, which would be considered the first deflection after the
diastole that is produced because of the atrial depolarization?
-T wave
-S wave
-Q wave

-P wave ANS: P wave
This occurs because of the atrial depolarization of the heart.
The Bundle of His has an intrinsic firing rate of which of the following?
-40 to 60 beats per minute
-30 to 60 beats per minute
-60 to 80 beats per minute
-80 to 100 beats per minute ANS: 40-60 beats per minute
The Bundle of His is located at the superior portion of the interventricular septum. The
Bundle of His is actually the pathway of the electrical impulses that lead out of the SA node.

correct?
-Hyper tension
-Hypoxemia
-Hypotension

-Hypoplastic ANS: Hypotension
Hypertension: high blood pressure
Hypoxemia: low oxygen concentration in the blood
Hypoplastic: when an organ is abnormally small because of a problem with development
prior to birth
Hypotension: low blood pressure
The aVR lead picks up electrical activity from which of the following?
-The center of the heart to the right arm
-The center of the heart to the left leg
-The center of the heart to the left arm
-From the left arm to the left leg ANS: The center of the heart to the right arm
The center of the heart to the left leg: aVF
The center of the heart to the left arm: aVL
The center of the heart to the right arm: aVR
From the left arm to the left leg: lead III

The Q wave should have a duration of less than how many seconds?
-0.30 seconds
-0.20 seconds
-0.10 seconds
-0.04 seconds ANS: 0.04 seconds
The Q wave should have a duration of less than 0.04 seconds. It is the first negative
component of the QRS complex and if it lengthens, it could be indicative of a myocardial
infarction
When the mitral valve opens, the blood flows from the left atrium to which of the
following?
-The right atrium
-The left ventricle
-The right ventricle
-The lungs ANS: The left ventricle
