Asystole

Question 6

QRS depolarization equals

Answer 6

ventricular

Question 7

P wave equals

Answer 7

atrial

Question 8

NSR

Answer 8

p wave- QRS- T wave
peak of P wave equal distance to QRS

Question 9

V-fib

Answer 9

no pattern

Question 10

V-tach

Answer 10

sharp peaks with pattern

Question 11

Asystole

Answer 11

flat line, lack of QRS

Question 12

flutter

Question 13

chaotic

Answer 13

fibrilation

Question 14

bizarre

Answer 14

Tachycardia

Question 15

Periodic wide bizarre

Answer 15

PVCs (short run of v-tach)

Question 16

non lethal arrhythmias

Answer 16

PVCs
low-moderate priority
moderate if:
6 or more PVC in a minute
more than 6 in a row
R on T (PVC falls on Twave)

Question 17

Lethal arrhythmias

Answer 17

high priority
will kill within 8 minutes or less
Asystole & v-fib
low/no cardiac output (no pulse)-> no brain perfusion -> confusion and death

Question 18

potentially lethal arrhythmias

Answer 18

v-tach
potentially lethal
Cardiac output present (pulse)

Question 19

Answer 19

Ventricular, Lidocaine or amiodarone

Answer 20

ABCDs
Adenocard (adenosine): fast IV push
Beta-blockers (-olol)
CCBs
Digitalis (digoxin), Lanoxin

Question 21

v-fib & systole treatment

Answer 21

defib for vfib (defibrilate)
epinephrine (1st) and atropine (2nd) for asystole
