Atrial dysrhythmias

Question 1

Atrial fibrillation

Answer 1

rapid, disorganized electrical activity- ectopic atrial pacers replace the normal SA node pacer. Atria quiver, leading to potential thrombus formation.

Question 2

Atrial fibrillation rate

Answer 2

can be slow (120)

Question 3

Atrial fibrillation rhythm

Answer 3

irregular

Question 4

Atrial fibrillation p wave

Answer 4

not present- replaced by fibrillatory waves

Question 5

Atrial fibrillation QRS

Answer 5

normal

Question 6

Atrial fibrillation ST

Answer 6

some depression

Question 7

Atrial fibrillation T

Answer 7

may be inverted

Question 8

Atrial fibrillation causes

Answer 8

long standing HTN, valve disease, HF, CAD, sick sinus syndrome, Pericarditis, Post CABG,, hyperthyroidism

Question 9

Atrial fibrillation effects

Answer 9

can be asymptomatic, or can have heart palpitations, SOB, dizziness, syncope, angina

Question 10

Atrial fibrillation treatment

Answer 10

Rate control drug: diltiazam, verapamil, digoxin, metoprolol. And, anticoagulation: ASA for low risk, Warfarin for high risk or Pradaxa/Xarelto. Can also do direct current cardioversion (anti coagulate before), radio ablation or install a permanent pacemaker.

Question 11

Atrial flutter rate

Answer 11

atrial rate is fast (PP) and ventricular rate is slow (RR)

Question 12

atrial flutter P wave

Answer 12

characteristic saw-tooth appearance

Question 13

atrial flutter QRS

Answer 13

normal

Question 14

Atrial fibrillation ECG

Answer 14

Question 15

Atrial Flutter ECG

Answer 15
