implanted device, continuous monitoring

Answer 12

heart disease
family history
abnormal baseline ECG
syncope
driving/flying

Question 13

2 mechanisms of tachycardia?

Answer 13

automatic focus: from one cell

Re-entry: eg. through 2 limbs of circuit

Question 14

explain what happens with conduction in re-entry causing tachy

Answer 14

retrograde conduction, via transient conduction block

Question 15

3 places you get re-entry tachycardias?

Answer 15

• atrial flutter (R atria)
• A-V node (dual A-V node pathyways
• ventricular tachy (around scar)

Answer 17

AV-node

Question 18

what parameter determines the ventricular rate in AF?

Answer 18

refractory period

what’s the problem with AF re heart function?

Answer 19

decreases LV filling time
increased LA pressure
pulmonary congestion
