Test 1
Delegation
Fundamentals of EKG interpretation Management of patients with Dysrhythmias
- The activity of the heart
- EKG can tell about the electrical function of rhythm disturbances & conduction
disturbances
Polarization the heart is getting ready and then fires (depolarization) and repolarization
it restarts
- The atrium is giving P wave
- QRS comes from the ventricle
The 3 pacemakers of the heart are:
SA Node (60-100 bpm)
AV Node (40-60 bpm)
Ventricle (20-40 bpm)
, - SA node is located in the atrium
100-160 bpm that the SA Node can fire only for tachycardia
- If over 160 it is considered atrial tachycardia (a different part of the heart)
PR Interval is from the beginning of the P to the beginning of the Q
- Normal is .12 to .20 seconds
- The isoelectric line should be flat
- P is from the atrium
- QRS is from the ventricle
- T wave is recovering
The Q is the first to find a negative deflection
- every box is .04
Normal Sinus Rhythms = Regular
- To measure regularity
- 60-100
- P wave: normal and upright
- One P wave in front of every QRS
- PRI: .12-.20 seconds and constant
- QRS: less than .12 seconds
6-second strip
- Three black lines on top of the paper
- 30 big boxes going across
- 30 X .20 = .6
- Each big box is .20
Sinus bradycardia
- Less than 60
Half an amp of Atropine is given for symptomatic bradycardia
Sinus Tachycardia
- Over 100 bpm
Sinus Arrhythmia
, - Irregular
- 60-100 bpm
- 1 p in front of QRS
- Gets longer on exhalation pts
CARDIAC 🫀

, Eco-Cardiogram:
- Sound waves are sent into your chest by a transducer.
- These waves bounce off of the heart and create images.
- It shows:
- the size and shape of the heart
- how well chambers & waves are working
-blood flow through the heart ( Doppler)
-any abnormalities (blood clots, fluid buildup, heart muscle damage)
Ejection Fraction:
- Measurement to assess how well your heart is pumping blood.
- It tells you what percentage of blood is in the heart's left ventricle is pushed out
with each heartbeat
- Measured with echocardiogram
Normal EF: 50%-70%
Borderline EF: 41%-49% (may indicate mild dysfunction)
Low EF: 40% or below (may indicate HF)
Cardiac ablation therapy is a minimally invasive procedure that creates scars on heart
tissue to stop the electrical impulses that cause irregular heart rhythms.
