sinus tachycardia causes
Give this one a try later!
stress
- acute blood loss
- anemia
- shock
- pain
- hyper/hypovolemia
meds that stimulate sympathetic response
POTS syndrome
asystole management
Give this one a try later!
, high quality CPR
identifying underlying causes
Hs & Ts (possible cause)
- hypoxia
- hypovolemia
- hydrogen ion (acid-base imbalance)
- hypo/hyperglycemia
- hypo/hyperkalemia
- hypothermia
- trauma
- toxins
- tamponade (cardiac)
- tension pneumothorax
- thrombus
what does the QRS complex show?
Give this one a try later!
ventricular depolarization (contraction)
asystole characteristics
Give this one a try later!
absent QRS complexes confirmed in 2 different leads
P waves may be apparent for a short duration
no heartbeat, palpable pulse, or respirations
atropine
,Give this one a try later!
increases heart rate and improves atrioventricular conduction by blocking
the parasympathetic influences on the heart
initial treatment for:
- symptomatic 3rd degree AV blocks
- sinus bradycardia
- asystole
ventricular fibrillation management
Give this one a try later!
defibrillation
CPR
administration of amiodarone & epinephrine may facilitate spontaneous
return of pulse
patient education for pacemaker
Give this one a try later!
leave incision uncovered and observe daily for redness
avoid tight restrictive clothing over incision
avoid heavy lifting for two weeks
restrict movement of arm until incision is healed
check pulse daily
main characteristic of 1st degree heart block
, Give this one a try later!
PR interval is regular/constant BUT is greater than 0.20 seconds
symptoms of cardiac tamponade
Give this one a try later!
arterial hypotension
tachycardia
decreased output
main characteristic of atrial flutter
Give this one a try later!
atrial rate is 250-400 bpm
saw-tooth P waves
premature atrial contractions (PAC) characteristics
