WEEK 7 - PTA152 - Heart Rhythms EKGS Telemetry

Atrial Depolarization and contraction

• P wave

• QRS wave

• T wave

Sinoatrial (SA) Node

​ (a)  

Origin of Conduction

Sinus Rhythm

-Basic Rate of ​ (b)  

-Autonomic Nervous System

-Circulating​ (c)  

Atrial Conduction Pathways

-Results in contraction both ​ (d)   ​

• "Pacemaker"
• 70bpm
• Hormones
• atria
• ventricles
• Levels

​ (a)   Node receives signal from ​ (b)   Node

-To initiate COORDINATION with Ventricles

Bundle of His

-Purkinje Fibers/Network

-Contraction of ​ (c)  

• AV
• SA
• Ventricles
• Atria

If the QRS is wider or different something is going on with ventricles

• True

• False

Our scope of practice as PTA is to see that this is a dangerous EKG, and we have to stop treatment and get of a hold of a nurse right away or this is a treatment where we need to slow down a little bit and adjust

• True

• False

The EKG Strip "must" be ____ seconds

-Count all the "p-waves" x 10 = HR

-Count all the "QRS" x 10 = HR

-They *should* match!!

• 8

• 3

• 66

• 6

• 4

It makes sense if you count all the P waves and the all the QRS, You should get the same number right???

YES

if you don't... you have ​ (a)  

• BAD ARRHYTHMIA
• AWESOME ARRHYTHMIA

<60 bpm, no additional abnormalities

• Bradycardia

• Tachycardia

>100-160 bpm, no additional abnormalities

• Bradycardia

• Tachycardia

In OUR world as PTAS is Bradycardia ok? and why?

• Yes

• GIRL no

• too much lines

• You can actually see the QRS but it's just going slower
