What is
Sinus Rhythm?
Rate:
PR:
QRS:
p wave:
|
|
Definition
Rate: 60-100
PR: .12-.2
QRS:.06-.12
p wave: one per QRS. regular |
|
|
Term
What is Sinus Rhythm with
Premature Atrial Depolarization?
two different kinds are:
looks like: |
|
Definition
sinus rhythm with an ectopic impulse in the atrium but outside of SA node.
unifocal: all PADs from same ectopic focal
multifocal: PADs from different focals
looks like random beats are early
|
|
|
Term
|
Definition
| SA rate of 300/min with random QRS |
|
|
Term
What is
Atrial Fibrillation?
p wave:
risk:
controlled if: |
|
Definition
rapid multifocal ectopic firings in atrium.
Only irregular strong pulses go through AV node to result in a QRS.
no p-wave
risk for blood clot in atrium
controlled if rate <100/min |
|
|
Term
What is
Junctional Rhythm?
Rate?
Regular?
P wave looks like? |
|
Definition
When AV node acts as pacemaker.
Rate: 40-60
Regular
p wave is either
-
hidden in QRS
-
after QRS
-
inverted before QRS and <.12
|

Term
What is sinus rhythm with
premature ventricular complexes (PVDs)?
possible rhythms: |
|
Definition
A random impulse from ventricle results in wide QRS and no p-wave
possible rhythms: bigeminy, trigeminy, couplets. also unifocal or multifocal (does each PVD look the same or different?) |
|
|
Term
What is
Ventricular Tachycardia
rate:
p waves:
regular?
QRS:
risk: |
|
Definition
rate: 100/min
no p waves
regular
wide QRS
risk: blood clot in atrium |
|

Term
What is Ventrical Fibrillation?
regular?
rate?
p wave?
|
|
Definition
very irregular
rate 300+/min
no p-wave. no pulse |

Term
| What is 1st degree AV block? |
|
Definition
| sinus rhythm with prolong PR (> .20 sec) |
|
|
Term
| What is 2nd degree block type I |
|
Definition
| PR progressively increases until a QRS is dropped |
|
|
Term
| What is 2nd degree AV block type II? |
|
Definition
Occasional block at AV node resulting in missing QRS.
Regular rhythm with some p waves that have no QRS |
|
|
Term
What is
3rd degree AV block? |
|
Definition
Complete AV block.
Atrium fires with normal p-p intervals. Ventrical fires with normal r-r intervals that do NOT match up with p waves. |
