No P Waves, QRS at reg
intervals
Sawtooth or FLUTTER WAVES
Tx: Anti coagulants, TEE,
Atrial Flutter
synchronized cardioversion
Adenosine, beta blockers,
calcium channel blockers,
digitalis (digoxin) (Fluttering in a
circle singing "ABCDs")
Episodes of abnormally
fast/racing heartbeat (between
150-250)
Normal QRS w/ reg intervals
Supraventricular
Tachycardia (SVT)
Tx: first - valsalva's maneuver,
carotid massage, ice to face
Adenosine, beta blockers,
calcium channel blockers, dig
stimulus can be caffeine,
nicotine, alcohol stress
common but if pt has cardiac
Premature Atrial
probs it can cause ischemia
Complexes (PAC)
usually asymptomatic
tx: take away trigger

Can deteriorate to V Fib
Tx: check pulse and LOC... if
they have a pulse: synchronized
Ventricular Tachycardia (V- cardioversion
tach) Vasopressin, Lidocaine,
Amiodarone, Magnesium, Epi (V
TACH = V LAME)
if pulseless = CPR and
defibrillation
3 or more PVCs in a row V-tach
abnormal heart rhythm which
results in quivering of ventricles
Ventricular Fibrillation (V-
fib) FATAL RHYTHM
Tx: Defibrillation, CPR
no electrical impulses
unconscious and pulseless
Asystole
DO NOT START CPR UNTIL YOU
CHECK TWO LEADS
TX: CPR, epi or vasopressin
- Elective procedure (informed consent is needed)
Cardioversion - Synchronized with QRS
- 50-100 Joules
- Emergency (call code)
- V-fib / V-Tach
- Begin with 200 joules (can go up to 300)
Defribrillation - No CO
- Synch off
- Make sure O2 is shut off before starting to avoid fire!
- No one can touch bed
