conduction defects that cause delayed or blocked transmission of sinus impulses through the AV node.There are three degrees ranges from benign to severe

Question 5: Atrial fibrillation: tx

Answer:

synchronized CV medsto slow ventricular rate, anticoagulants to decrease the risk for stroke

<60 bpm, regular Question 16: sinus tachycardia: tx

Answer:

only if sympotomatic

Question 17: Why are anitdysrhythmic drugs used

Answer:

Answer:

for emergency, they should also have what kind of pacemaker they have on them

Answer:

it occurs when the pt HR falls outside the programmed limits Question 23: pt with pacemakers: what is the electrical cautions

no MRI, Question 24: Atrial fibrillation: def

Answer:

irregularly irregular, no identifiable p wave, variable ventricular rate Question 25: Sinus Bradycardia: tx

Answer:

only if sympotomatic, pacemaker or atropine Question 26: v-fib: tx

Answer:

immediate defibrillate Question 27: what type of rhythms are fatal supraventricular or ventricular rhythms

Answer:

ventricular

Question 28: What is defibrillation used for

Answer:

to treat rhythms that effect cardiac output and the client's welfare (electrical shock is administered to depolarize all cells of the heart at the same time) it stops the abnormal rhythm
