Arrythmias Flashcards
4 types of cardiac rhythms
Normal sinus impulse formation
Abnormal impulse formation
Abnormal impulse conduction
Escape rhythms
4 mechanisms for arrhythmias
Altered automaticity
Triggered activity
Conduction blocks
Re-entry
Abnormal impulse formation has 2 mechanisms
Altered automaticity
Triggered activity
abnormal conduction has 2 mechanisms
Conduction blocks
Re-entry
Altered automaticity abnormal impulse happens when
Arrhythmia
triggered activity abnormal impulse happens when?
Abnormal impulse formation
what are reentry abnormal conduction blocks
Abnormal conduction or altered conduction path
Inhomogeneous action potentials
what happens to the current in reentry conduction block
goes around the block. makes its own path
what is seen here in atrial fib
Fine fibrillation wave ( f wave ) or coarse flutter waves.
What is this arrhythmia
Premature ventricular complex PVC
couplet or triplet
What arrhythmia
Look at PR interval. between p wave and QRS complex. It is long
1st degree AV block
What arrhythmia
Look at PR interval– long
misses a QRS sometimes
2nd degree AV block—MOBITZ type I
Mobitz type I aka:
what is it always a block of?
2nd degree AV block
Block within the AV node
What arrhythmia
look at different PR intervals some no QRS
BIG R wave
Wandering pacemaker
3 Pre-excitation syndromes
Wolff-Parkinson-white syndrome
Loan ganong-Levine syndrome
Madani- type
Left bundle branch block
look at the s wave goes way down
longer to ventricular depolarize
Right bundle branch block
look at the widened QRS
