EKG Rhythms Flashcards

1
Q

what is the causes of normal sinus rythym

good functioning heart

good sv, CO, preload, after load and good perfusion

Q

what is important to do for a pt who appears to be in sinus rhythm

A

make sure they are asymptomatic and that they are not in PEA (pulsless electrical activity) pt will not have a pulse and be unresponsive
*do not shock for PEA

Q

what is it called if pt is in normal sinus rhythm but has an elongated PR interval (> 0.20)

A

AV block and if it is consistent then its called 1st degree heart block
*people can live with this rhythm

Q

what is the treatment for 1st degree heart block

A

monitor pt, pt can live with this

*check cap refill, skin color, pulses to see if they occur with monitor

A 
hypoglycemia

Q

what are the different variations with sinus bradycardia

A

elevated T wave- caused by hypokalemia

ST depression- caused by injury or untreated hypovolemia

Q

what would the treatment be for sinus bradycardia

A

treated only if the client is experiencing symptoms

IV atropine, fluid challenge, or pacemaker

Q

what is the tx for sinus tachycardia

A

(tx the cause)
NS fluid challenge
maybe BB to slow heart rate

14
Q

is the sinus tachycardia pt perfusing well

A

check pulses and color, if rate is consistent the perfusion will decrease
*due to loss of atrial kick and too fast to allow filling times

16
Q

umbrella term for unidentifiable rhythms
P waves often not identifiable
PR interval not measured
150-200bpm

A

supraventricular tachycardia (SVT)

17
Q

what are S/S of SVT

A

chest pain, SOB, lightheadedness/dizziness, confused, syncope

18
Q

what is the treatment for SVT

A 
vagal maneuver
slow heart rate with meds 
oxygen (if pt is stable)
adenosine (chem cardioverter if stable)
*if pt is UNSTABLE electrically cardiovert (synchronized)
19
Q

does the pt who has SVT have perfusion

A

no because theres no atrial kick

20
Q

atrium quivering, irregular, excess P waves but not true P waves

A

atrial fibrillation

21
Q

what are S/S of A fib

A

dizzy/lightheadedness, syncope, confusion, fatigue, SOB, bird flopping feeling

22
Q

what is the tx of A fib

A

if the HR is too fast slow it with meds
*make sure pt is on anticoags to reduce risk of clot formation
must get a TEE to r/o clots before cardioversion
the tx of choice is cardioversion

23
Q

what are risks of A fib

A

develop clots in the heart
stroke
PE
low BP and decreased CO

24
Q

sawtooth appearance

A

A flutter

25
Q

what are S/S of A flutter

A

SOB, anxiety, weakness, angina, syncope

26
Q

what is the treatment for A flutter

A

same as A fib- slow heart rate, anticoags, TEE before cardioversion
**can pace someone out of A fib- turn on pacemaker, dial up to what HR says, leave for a few sec, start turning down

27
Q

greater than 100 bpm
P waves unidentifiable
QRS wide and bizarre shape

A

V tach

28
Q

what are S/S of V tach

A

lightheadedness, dizzy, angina, syncope, SOB, absent or rapid pulse, LOC, hypotension

29
Q

what is the tx for V tach

A

O2, lidocaine drip, and shock quickly (shock out of chaotic rhythm)
NO cardioversion
there is no perfusion

30
Q

HR is undetermined, no PR interval, no P waves

A

v fib

*if v tach is untreated it goes to V fib

31
Q

how do you treat V fib (worse than v tach)

A

CPR, Defib (NO cardioversion)

theres no perfusion

32
Q

“flat line”

A

asystole

33
Q

if you see asystole what should you do first

A

assess leads are on, assess pt, check pulse

34
Q

how is systole treated

A

CPR- NO defib and theres not any perfusion
