ARRHYTHMIAS Flashcards
Adult CPR
Phone first
ABCs
30:2 cycles
100/min
1 ½ - 2 inches
Check rhythm after 5 cycles
Two main classes of Arrhythmias
Heartblock
Tachyarrhthmias (>100bpm)
The four types of heart block
SAN block
AVN block
Intraventricular block
Hemiblock
The three types of AVN block
1st
2nd
3rd degree block
Two types of intraventricular block
Right bundle branch block (RBBB)
Left BBB
Two main types of tachyarrhythmias
Narrow complex (QRS<120msec)
Broad or Wide complex (QRS.120msec)
Types of broad complex tachyarrhythmias
Ventricular tachycardias
Ventricular fibrillations
Ventricular ectopics
SVT or AF with abnormal conduction
Difference between ventricular tachycardia and ventricular fibrillation
Ventricular fibrillation is irregular whilst ventricular tachycardia is regular
Types of narrow complex tachyarrhythmias
Regular
Atrial flutter
SVT
Sinus tachycardia
Irregular
Atrial fibrillation
Most common supraventricular tachycardias
AV nodal re-entrant tachydardia (AVNRT)
AV reciprocating tachycardia (AVRT)
Atrial tachycardia
Four main classes of antiarrhythmic drugs
Class 1- Sodium channel blockers
Class 2- Beta blockers
Class 3- Potassium channel blockers
Class 4- Non DHP- CCB
Other antiarrhythmic drugs

Three examples of premature beats
Premature Junctional Complex
Premature atrial complex
Premature ventricular complex
Supraventricular Tachycardia
Heart rate >150bpm
What to check for on an ECG to determine type
Rate
Rhythm
P waves
PR interval
P and QRS correlation
QRS rate
Pacemaker
Raye of the sinus node
60-100bpm
Rate of the AV junction
Fire at a rate o 40-60bpm
Ventricular rate
<40bpm
Types of arrhythmia based on QRS complex and width
Narrow QRS tachycardia

Multifocal Atrial Tachycardia
Types of atrial tachycardia
Focal atrial tachycardia
Multifocal atrial tachycardia (MAT)
Atrial flutter
Re-entrant atrial tachycardia*
Paroxysmal atrial tachycardia
A type of atrial tachycardia that begins and ends abruptly
Wide QRS complex tachycardias
Regular
Ventricular tachycardia
SVT aberrant
Ventricular fibrillation
Irregular
PVT
A-Fib
Narrow QRS bradycardia
Sinus bradycardia
A-fib
