Question 1

what is the normal sinus rhythm of the heart

Answer 1

SA node generates at 60-100

Question 2

what are dysrythmias or arrythmias?

Answer 2

• abnormalities of electrical conduction which can effet heart rate or cardiac rythm
• dangerous when heart beats are to fast or to slow, generally less than 50 and greater then 100

Question 3

Risk factors for AFIB

Answer 3

-advanced age w valvular disase
-HTN
-CAD
-congenital disorder
_HF
-diabetes
-obesity
-hyperthyroidism
-pulmonary hypertension
-embolism

Question 4

Signs and Symptoms of A fib

Answer 4

• irregular pulse
• dizzy (lightheaded because decrease in bp)
• SOB
• fainting (decrease in BP)
• palpitations (usually described as skipped or extra beats)
• decreased BP if not compensating

Question 5

what are some nursing considerations for Atrial fibrillation

Answer 5

• bp, HR, RR, 02 sats
• drug to drug interaction
• electrolytes (k+, Na+, Ca++)
• hepatic/renal
• hx, heart failure
• monitor for signs and symptoms of clotts

Question 6

Diagnostics for Afib

Answer 6

• ECG (primary)

- hotler monitor

Question 7

interventions when someone is in A fib

Answer 7

• spontaneous conversion
• Cardioversion (convert into normal sinus rythm)
• pharmacology

Question 8

pharmacology for A-fib

Answer 8

• beta blockers: metoprolol (decrease hr give heart more filling time to increase CO)
• antiarrythmic: Digoxin, (increase force of myocardial contraction Increase CO)
• anticoagulants: warfarin, heparin, dalteparin
