ECG Flashcards
What are the 6 steps to ECG assessment.
Any electrical activity QRS rate QRS rhythm is it regular Is QRS normal length Atrial activity present Is atrial activity linked to ventricular
If QRS is <0.12 what does this indicate?
Impulse is of atrial origin
If QRS is >0.12 what does this indicate?
Impulse is of ventricular myocyte origin
How long should the P-R interval be?
0.12-0.20
Sinus Arrythmia
P and QRS waves presents
Heart rhythm fluctuates with inspiration
Narrow QRS
Premature Atrial Complexes
Narrow QRS
Flattened or notched P wave
SVT
Narrow QRS
No p waves
Tachychardic
Regular Rapid rhythm
Atrial Fibrillation
No P waves
QRS comple
Irregular irregular pattern
Chaotic baseline
Atrial Flutter
Saw tooth
QRS complexs present
Usually 2:1 or 4:1 atrial conductance
First Degree Heart Block
Regular Rhythm
P waves and QRS complex are present
Prolonged PR >0.20
Second degree heart block
Mobitz I
Irregular rhythm
Progressively prolonged P-R interval
