CARDIAC ARRYTHMIAS - Coggle Diagram
CARDIAC ARRYTHMIAS
Six Rythms tested on NCLES
Asystole
Atrial flutter
Rapid
P-wave depolarization
in a
saw-tooth
(flutter)
Atrial fibrillation
Chaotic
P-wave depolarization's
Ventricular fibrillation
Chaotic
QRS depolarization's
Ventricular tachycardia
Wide,
bizarre
QRS, always disceernable
repeating
pattern
Premature ventricular contractions
Periodic
wide,
bizarre
QRS's
"One snapshot of a tachycardia
Low to moderate priority
Be concerned
if there are 3 circumstances
More than
6
per minute
6
in a row
PVC falls of
T-wave
of previous beat
Treatment
PVC's (ventricle)
Lidocaine (ventricular, lasts longer)
Amiodarone
V Tach (ventricle)
Lidocaine
Supraventricular arrhythmias (atrial arrhythmias)
"
ABCDs of Atrial Treatment
"
A
denosine/Adenocard
push fast
IV push ->
8 sec
or faster
Temporary asystole around 30 seconds (normal)
B
eta-blockers (-lol)
C
alcium channel blockers
D
igoxin (Digitalis) Lanocin❗
V-Fib
"
For V-Fib you Dfib
"
Shock= 200 defibrillate
A
systol
E
"
A for Atrophine and E for Epi but give it reverse
"
Epinephrine
Atropine
S/E anticholinergics
4 Rythm strip tracing to know by sight
Normal sinus rythm
P wave
before every
QRS
followed by a
T wave
,
P wave
equally distant to one another (doesn't matter if they go up or down)
V-Fib
V-Tach
Asystole
Terminology
QRS depolarization
Always refer to
ventricular
P wave
Atrial
Potentially life threatening arrhythmia
Still have cardiac output
V-tach
No pulse
Pulseless v-tach
Same as asystole and V-Fib
After 8 mins consider dead
Lethal Arrhythmias
(High priorities‼)
Both have no cardiac output
-> no brain perfusion
-> dead in
8
minutes
Asystole
V-fib
