Mechanics of the heart
Ectopic Beats are
Extra Beats
T Waves Represent
Ventricular Repolarization
Describe both Multifocal and Unifocal PVC's
Multifocal PVC's are different
Unifocal PVC's are the same
Describe Atrial Flutter
Fast flutter of P waves
RDI calculates what
RERA's
Describe Bradycardia
Rate less than 40BPM
What is the Normal Heart Rate
60-90BPM
Describe 2nd Degree Heart Block Type 1 and what it's nickname is
Gradual Increase in PR intervals until QRS is skipped.
Known as Wenckebach
This arrhythmia is severe and has no discernable QRS
VFIB
Describe Atrial Fibrillation
Very fast unorganized P waves
More dangerous
"irregularly irregular"
Describe Tachycardia
Rate faster than 90BPM
A block between the atria and ventricles is
AV Blocks
Describe 2nd Degree Heart Block Type 2 and what it's nickname is
Suddenly skips a QRS without warning
Known as Mobitz (Hay Block)
Describe Sinus Arrhythmias
Normal, but rhythm is irregular from beat to beat
What does this formula calculate?
Number of Arousals/TSTx60
Arousal Index
P Waves represent
Atrial Contraction
What AV Block degree has no association between QRS and P waves?
Describe PAC's
Irregular rhythm due to early P wave
Describe Ventricular Tachycardia
3 or more PVC's in a row
What is the formula to find Sleep Latency?
Sleep Onset-Lights off/2
QRS Complex represents
Ventricular Contraction/Depolarization
Counting from one R wave to the next consecutive R wave (the R-R interval) is used to
Describe a PVC
Wide bizzare looking QRS Complexes
Which Heart Block has a prolonged PR interval?
1st Degree AV Block
Apneas and Hypopneas
