●● Third degree block
Answer: no P wave for every Complex
no constant PR interval
Sx: hypotension, angina, HF
Cause: Rheumatic fever, hypoxia, MI, dig toxicity, beta blocker
overdose
Tx: Epi drip to increase heart rate, permanent pacemaker
●● First degree block
Answer: prolong PR interval
Cause: hyper/hypokalemia, dig toxicity, Ca.Channel Blockers,
amiodarone
Tx: Atropine
●● Torsades de pointes
Answer: twisting about the points
cause: alcoholic, anorexia
Sx: hypomagnesemia <1.4, hypokalemia, Tetany, tremors, hyperreflexia
,Tx: Mag push, Potassium push
●● Ventricular Fibrillation
Answer: uncoordinated and chaotic
Cause: MI
Sx: loss of consciousness, pulseless, sudden death
Tx: 1-check pulse 2-pulseless; CPR/Defib pulse; Epi every 3-5min 1mg
●● Asystole
Answer: no ventricular contraction
must be assessed in more than 1 lead
Tx: CPR, epic every 3-5min 1mg,
●● pulseless electrical activity (PEA)
Answer: Hs: Hypovolemia, Hypoxia, Hydrogran ions (acidosis),
Hyper/hypokalemia, Hypothermia
Ts: Toxins, Tamponade, Thrombosis (cardiac), Thrombosis (pulmonary),
Tension pneumothorax
●● Supraventricular Tachycardia (SVT)
Answer: HR 150-200bpm T&P merge
Cause: overexertion, stress, stimulants
Tx: 1-vagal maneuver (cough/bear down)
, 2-AV nodal blocking agents (CCB, Beta blockers, amiodaraone)
3-IV adenosine (can cause flat line)
4-Cardioversion
●● Ventricular tachycardia
Answer: EMERGENCY!
Sx: lightheadedness, weak, unconscious
Cause: MI, aneurysm, CAD, hyper/hypokalemia, PE
Tx: 1-check pulse/BP
2-stable: amiodarone
unstable: hypotensive w/ pulse=cardiovert
unstable: NO PULSE- CPR/Defib
●● Sinus tachycardia
Answer: HR >100bpm
P precedes each QRS complex, normal rhythm
Cause: fever, exercise, anxiety, dehydration, pain, ETOH
Tx: correct cause, beta-olol, CCB -pine
●● sinus bradycardia
Answer: HR <60bpm
P precedes each QRS complex, rhythm normal
