Ventricular Rhythm Facts
what is the inherent rate of the ventriculer pacemeker?
20-40bpm
what is a Couplet PVC
Two consecutive PVC's which can either beunifocal couplet or a multifocal (non identical) couplet
what must you do when nameing all premature complexes?
Identify the underlying rhythm
What Junctional Rhythm has a Heart Rate below 40
Junctional Bradycardia
What is the inherent of the AV Junction?
40-60 bpm
what is an R on T PVC
PVC is close or on top of the the preceding T-wave
what are the characteristics of a Run of Ventricular Tachycardia
3 or more PVC's in a row
heart that starts and stops
underlying rhythm
Regular but interrupted
greater than 100 bpm
What does polymorphic and monomorphic mean?
QRS varies in appearence
QRS looks the same
What is the rhythm regularity of a PJC
What are the key characteristics of a Juntional P-Wave?
Hidden or Inverted
what is an Unifocal PVC
All PVC's look the same on the strip and come from the same focus
what are the characteristics of Torsades de Pointes
Regular or Irregular
Rate > 200bpm
The QRS complex oscillates
T wave opposite of QRS if seen
What does oscillates mean?
QRS repeatingly going from one size to a different size
What are the characteristics of a junctional bradycardia
Regular rhythm
Hidden or inverted p-wave
Heart Rate Below 40 bpm
What are the names of the two AV Junction impulses that travel in two directions
Antegrade and Retrograde
What is an Agonal Rhythm
before dying which has a bpm of less than 20 bpm
what characteristics of V-Fib?
Rate can't be measured
Regularity cannot be determined
No P-waves
What is the difference between asystole and P Asystole
Asystole is a complete flatline, but P Asystole is when the SA node is firing, but the ventricles are not responding; eventually, it will stop
What are he characteristics of an Accelerated junctional Rhythm
inverted or hidden p-wave
Heart rate of 60-100
Regular rhythm
What is the name of the AV Junction impulse that travels backward
Retrograde
what does PEA stand for
pulseless electrical actitvity
what is asystole
flatline
Purkinje fibers may not reach the atria because the stimulus gets blocked by the AV node
What are the characteristics of a PJC
Regular but interrupted rhythm
any heart rate/Underlying rhythm
inverted or hidden p-wave
What is the name of the AV Junction impulse that travels forward
Antegrade
