A

500 micrograms atropine IV

repeat upto 3mg

21

what suggests mobility of leaflets?

length of murmur suggests?

A

opening snap - pressure in left atrium is greater than the pressure in left ventricle

severity

loud S1

22

uptight t waves
dominant r in V2

> circumflex or right coronary

24

II,II, aVF

25
Q

A

V1-V6, I aVL

proximal left anterior descending

26
Q

lateral MI

A

I, aVL, +/-V5,V6

left circumflex

27

coagulase negative staphylococcus epidermis

2 month tho

30
Q

why does Omeprazole affect clopidogrel?

A

pro-drug activated by the enzyme CYP2C19

omeprazole is an inhibitor of this enzyme

31
Q

Cardiac Resynchronisation Therapy?

A

Heart failure patients taking maximum triple therapy with widened QRS complexes

Biventricular pacemaker would improve cardiac function

32
Q

what does a wide QRS indicate in HF?

A

electrical signals between left and right sides of heart are not working well

33
Q

symptomatic bradycardia

A

Isoprenaline/adrenaline infusion is an alternative treatment to atropine/transcutaneous pacing

stop warfarin

give IV vitamin K 5mg
prothrombin complex concentrate

35
Q

Buerger’s disease

A

raynaud

intermittent claudication

finger ulcerations

36
Q

Why do ACEi cause a cough as a side effect?

A

build up of bradykinin in the lungs which acts as an irritant

37
Q

Thiazide diuretics work by?

A

inhibiting sodium absorption in the distal convulated tubule

  • hyponatraemia
38
