Q

Why does the junctional Rhythm have a slow conduction time?

A

To allow time for the Atria to contract an empty contents into the ventricles

Q

What does a normal P wave look like? Where does it originate?

A

Normal P wave:

Smooth and round, originates and sinus node

17
Q

What does the PRI represent?

A

PRI represents the time from the onset of atrial depolarization to the onset of ventricular depolarization

18
Q

What is a normal PRI?

A

0.12 - 0.20 seconds (normal PRI)

19
Q

If an Impulse is conducted from the Atria to the ventricles through a conduction pathway that bypasses the AV node, how does this present on ECG?

A

Shorter PRI

20
Q

This represents the conduction of electrical impulses from the Bundle of His throughout the ventricular myocardium

A

The QRS complex

21
Q

What is the key factor when evaluating a QRS complex?

A

The appearance of the QRS doesn’t matter, the key factor is the TIME of the complex.

22
Q

The point where the QRS ends is known as what?

A

J point

23
Q

What is a normal QRS interval?

A

0.10 or less

24
Q

What is the significance of a wide QRS complex?

A

Bundle branch block
