34
what does a prolonged QT segment increase the risk of
arrrhythmias
35
when does a systolic heart murmur happen?
after heart sound 1
36
why does S3 happen?
cos blood oscillates in ventricles due to rapid filling and frail/compliant ventricle
37
why does S4 happen?
when blood is forced into a stiff ventricle
38
why does a split heart sound occur
because during inspiration, thoracic pressure becomes more negative, causing more blood to be sucked into the pulmonary artery, delaying the closure of the pulmonary valve. hence causing a de-synch with the aortic valve
39
6 characteristics to describe murmurs
``` timing location characteristics intensity radiation response to respiration ```
40
how does a pansystolic murmur occur
can be due to mitral regurgitation, after S1, as blood is being pushed out of the ventricle, it leaks back into the atrium, causing a long murmur until S2
41
how can an ejection murmur occur
aortic stenosis can cause an ejection murmur during systole as blood is forced through a narrower opening of the aorta during systole. it stops before S2
42
how to accentuate a mitral murmur?
listen at mitral area and roll to the left
43
what pathology is associated with a crescendo-decrescendo murmur
aortic stenosis

54
difference between a thrombus and an embolus
thrombus is blood clot forming on the endothelium | embolus can be any mass in the circulation system
55
3 stages of chronic arterial disease
intermittent claudication critical limb ischaemia acute limb ischaemia
56
how to differentiate intermittent claudication VS critical limb ischaemia?
intermittent claudication presents as muscular pain on exertion which is relieved by resting CLI is severe ischaemia that comes on with pain at night and when legs are horizontal. relieved in bed by hanging the legs off the bed at night. can present with tissue loss as ischaemia progresses.
57

``` smoking obesity high cholesterol hypertension diabetes age ```
58
what 3 features are part of Leriche's syndrome
claudication of thighs and buttocks absent/decreased femoral pulse male impotence/ED
59
why do ulcers form in PVD?
reduced blood flow, lack of nutrients, reduced healing. leads to necrosis and inability to heal.
60
difference between arterial and venous ulcers ``` Site Edge depth Base/colour gender ```
Arterial VS venous ``` pressure points VS gaiter region regular VS jagged punched out vs superficial necrotic, green VS pink and yellowish male VS female ```
61
2 types of gangrene that can occur
dry and wet gangrene
62
difference between dry and wet gangrene
infection VS no infection
63

``` pain pallor paraesthesia pulseless paralysis perishingly cold ```
64
what can cause acute limb ischaemia?
an embolus suddenly blocking off blood supply
65
how long is the window the save a limb from acute limb iscahemia?
6 hours, before necrosis starts
66
what is the presentation of an aortic abdominal aneurysm, before and after rupturing
palpable expansile region in the abdomen if ruptured - sudden back pain - hypovolaemic shock - LoC - sudden death
67
what can a carotid atheroma cause
embolus which cause TIA and stroke
68
presentation of varicose veins
ache in leg after standing for long night cramps venous ulceration superficial thrombophlebitis
69
classical features of DVT
``` calf pain pyrexia persistent tachycardia swelling of leg, along the vein pain when walking or standing warmth over inflamed area ```
70
key questions to ask in PVD history
acute/chronic when does it come on what makes it feel better (hanging from bed) pmhx - RF, stroke Dhx - SHx - smoking, exercise tolerance, ADLs
71
