Jan 01, 2016
Name this dysrhythmia:
Idioventricular
(ventricular bradycardia)
An ECG strip shows a rhythm with normal P-R, P’s are 1:1 with
QRS complexes, rate 70, rhythm regular, QRS 0.14 sec.
What is the name of the rhythm?
NSR with a bundle
An ECG strip shows wide QRS complexes at a rate of 170. No P
waves are seen. One possible interpretation of this rhythm
is V Tach. What is another possible
interpretation?
SVT with a bundle branch block
Describe how the marks on the border of the ECG paper can be
used to determine heart rate.
The marks are 3 seconds apart. Count the number of complexes in six seconds and multiply by
ten to find the heart rate.
Name the value of one small square on ECG paper:
1) In units of time (horizontal)
2) In metric units of length (vertical)
1) 0.04 Seconds
2) 1 millimeter
Describe the conventional method of standardization
of an ECG machine
A one millivolt impulse will cause a deflection of 10 mm (which is two large squares)
Name three different indications that PVC’s should be treated
1) Multifocal2) R on T phenomenon3) Coupled (or runs of VT)4) Associated with MI or ischemia
Where is the primary disease in patients with first, second, or
third degree block?
The A-V node
Name (in order) the components of the conduction system
of the heart.
Sino-atrial node(internodal pathways)Atrio-ventricular node
Bundle of HisBundle branchesPurkinje fibers
State in order the numbers used to determine the heart rate by
counting the large squares between R waves
(answer counting up to at least 7 squares)
300-150-100-75-60-50-43-37-33-30
Name this dysrhythmia
Controlled atrial fibrillation
Why is the sinus node normally in control of the heart?
Because it has the fastest inherent discharge rate
What are the normal values for:
1) P-R interval
2) QRS duration
1) 0.12 -0.20 seconds
2) Up to 0.10 seconds
Describe the triad of infarction
1) Pathological Q
2) Elevated S-T segment
3) Inverted T wave
