Guess that rhythm!
This rhythm is considered normal except the rate is <60 bpm.
Sinus Bradycardia
This is described as polymorphic v-tach.
Torsades de Pointes
P:QRS = abnormal
PRI: very irregular, constantly changing
3rd Degree AV Block
What is the difference between cardioversion and defibrillation?
Defib: emergency, no cardiac output, begin with 200 joules
Tx of V-tach
Pulse: Amiodarone, lidocaine, cardioversion
Pulseless: Defib, CPR, ACLS meds
This rhythm occurs when there is a problem with the SA node causing sinus pauses.
Sick Sinus Syndrome.
Rate: >100 bpm
Rhythm: regular
Ratio & PRI: unmeasurable
QRS: wide/bizarre
Ventricular Tachycardia
PRI: gets progressively longer until QRS is dropped
2nd Degree Type I
Shock PEA?
NO
Tx of PVCs
Amiodarone
Lidocaine
This rate rhythm becomes clinically significant if the rate is >0.51 as is can lead to R-on-T phenomenon.
Long QT Syndrome
This rhythm is referred to as irregularly irregular.
A-Fib
Described as a squiggle created by quivering.
V-Fib
Shock VF?
YES
Determine cause
Beta Blockers
Pacemaker
Occurs when a single impulse starts early in the atrium.
Premature Atrial Contractions
Distinguished by one or a few wide/bizarre/ugly shaped QRS complexes.
Premature Ventricular Contractions
PRI: consistent in time except when QRS complexes are dropped
2nd Degree Type II
Shock asystole?
NO
Tx of A-Fib
Diltiazem
Amiodarone
Digoxin
Cardioversion
Anticoags
Rate: 150-250 bpm
Ratio: too fast to determine
PRI: cannot be measured
QRS: <=0.12 sec
Supraventricular Tachycardia
Rate: 250-350
Rhythm: depends
Ratio & PRI: cannot measure
QRS: <=0.12 sec
P waves -> F waves
Atrial Flutter
Rate: normal
Rhythm: normal
Ratio= 1:1
PRI: >0.20 sec
QRS: normal
1st Degree AV Block
Shock pulseless VT?
YES!
Tx of SVT
Vagal Maneuvers
Adenosine or Diltiazem
Cardioversion
