-0.30 seconds
-0.20 seconds
-0.10 seconds
-0.04 seconds - <<<<CORRECT ANSWERS>>>0.04 seconds

-The elderly
,-40-60 years of age - <<<<CORRECT ANSWERS>>>The elderly
Fibrosis can occur at any age, but is most common with the elderly. They have a higher
incidence of AV block which can be caused by fibrosis in the conduction system
A dropped beat indicates what? (Skipped QRS wave)
____ degree heart block, type __ - <<<<CORRECT ANSWERS>>>Second degree
heart block, type I
With this rhythm, the PR interval will lengthen in each of the intervals until one QRS
completely disappears.
Which of the following characteristics would a good ECG technician have?

-They should have mechanical aptitude
-They should be able to follow directions
-All of the above - <<<<CORRECT ANSWERS>>>All of the above
Which of the following would be the main purpose of the heart valves?
-The prevention of back-flow of blood
-They assure that there is a uni-directional flow of blood through the heart
-Both A and B
-None of the above - <<<<CORRECT ANSWERS>>>Both A and B
Which of the following would be considered correct regarding the grid paper that is used
for an ECG?
-The grid paper consist of horizontal lines
-The grid paper is not heat sensitive
-The grid paper consist of vertical lines
-Both A and C - <<<<CORRECT ANSWERS>>>Both A and C
The grid paper that is used for an ECG test:
Consists of horizontal lines
Consists of vertical lines
Is heat sensitive
Is used for cardiac monitoring and ECG's
If a patient's heart becomes softened, it could cause changes in the electrocardiogram.

-Cardiomalacia
-None of the above - <<<<CORRECT ANSWERS>>>Cardiomalacia
, Cardiomegaly is an enlarged heart
Cardiopathy is any heart disease
Cardiomalacia is a softening of the heart
Potential causes of PVC's can be which of the following conditions?

Some of the causes would include:
Stimulants such as cocaine, coffee, nicotine or amphetamines
Increased catecholamines
Hypoxia
Heightened emotions
AMI
