Sinus Arrhythmia

100

sawtooth shaped waves occurring at 250 - 300?

what are flutter waves/atrial flutter 

100
What is the normal rate of a junction rhythm?
What is 40 - 60?
100

the defining characteristic of a first degree heart block?

What is a PR interval greater than 0.20 seconds

200
Atrial heart rate can be calculated by counting the what?
P-waves
200
What do you call a sinus rate less than 60?
What is sinus bradycardia?
200
What rhythm is irregularly irregular?
What is atrial fibrillation?
200
What is it called when the junctional rate is greater than 60?
What is accelerated junctional?
200

a heart block that has PR intervals that get progressively become longer until a QRS complex is dropped.

What is a 2nd degree type 1 (Wenkebach)

300

Using the R-R method for heart rate calculation, you divide the number of small blocks into...?

1500

300
What do you call a sinus rhythm that is accelerated above it's normal rate?
What is sinus tachycardia?
300

What shapes can an atrial P-wave have?

what is any
300

In a junctional rhythm, where is the p wave located?

It can be before, during, or after the QRS complex

300

In a second degree type 2, the pr intervals are usually

what is regular

400

What does the p wave represent

what is atrial contraction

400

Sinus Rhythms originate in this node

what is the SA node?


400
What does the word Paroxysmal in "Paroxysmal Atrial Tachycardia" mean?
It comes and goes / starts and stops abruptly.
400

What is junctional tachycardia?

Junctional Rhythm with a rate over 100.

400

a block in which the p waves are regular and the R waves are regular, but there is no correlation between them

what is a 3 rd degree

500

What is the normal range for a PR interval?

0.12-0.20 seconds

500
A pause that occurs when the sinus node's impulse is not conducted out of the sinus node itself is...?
What is a sinus block?
500

A beat that occurs early and the p wave has a different morphology than the normal beats?

What is a PAC (premature atrial contraction)

500

Why is the P-wave inverted in a junctional rhythm?

The impulse that depolarized the atrial originates below the atria, causing retrograde conduction.

500

which heart blocks have varying PR intervals?

what are 3 rd degree and 2 nd degree type 1
