100

This rhythm is considered normal except the rate is <60 bpm. 

Sinus Bradycardia

100

This is described as polymorphic v-tach. 

Torsades de Pointes

100

P:QRS = abnormal 

PRI: very irregular, constantly changing 

3rd Degree AV Block

100

What is the difference between cardioversion and defibrillation? 

Cardioversion: elective procedure, synchronized with QRS, 50-200 joules, consent form 

Defib: emergency, no cardiac output, begin with 200 joules

100

Tx of V-tach

Pulse: Amiodarone, lidocaine, cardioversion

Pulseless: Defib, CPR, ACLS meds

200

This rhythm occurs when there is a problem with the SA node causing sinus pauses. 

Sick Sinus Syndrome. 

200

Rate: >100 bpm

Rhythm: regular

Ratio & PRI: unmeasurable 

QRS: wide/bizarre 

Ventricular Tachycardia 

200

PRI: gets progressively longer until QRS is dropped

2nd Degree Type I

200

Shock PEA?

NO

200

Tx of PVCs

Amiodarone 

Lidocaine 

300

This rate rhythm becomes clinically significant if the rate is >0.51 as is can lead to R-on-T phenomenon. 

Long QT Syndrome

300

This rhythm is referred to as irregularly irregular. 

A-Fib

Described as a squiggle created by quivering. 

V-Fib

300

Shock VF?

YES

Determine cause

Beta Blockers

Pacemaker 

400

Occurs when a single impulse starts early in the atrium. 

Premature Atrial Contractions

400

Distinguished by one or a few wide/bizarre/ugly shaped QRS complexes. 

Premature Ventricular Contractions

400

PRI: consistent in time except when QRS complexes are dropped

Amiodarone 

Digoxin 

Cardioversion
