Q

define syncope

A

syncope is the loss of consciousness characterised by unresponsiveness, loss of postural tone and the spontaneous recovery without resuscitation efforts or interventions.

25
what is the issue with patients with unknown syncope?
as it hard to distinguish whether it has occurred because only 40-60% of syncopal events are witnessed - a large proportion of the elderly forget they had a fall within three months
26
what does the tilt table test do?
mimics postural hypotension - see if the feeling can be recreated - so that they can get a diagnosis
27
what happens to some elderly patients if the carotid is activated?
it can cause syncope
28
what is postural hypotension also known as?
orthostatic
29
what is the most serious and frequent accident in the 65+
falls
30
what is the main cause of disability and death in the 75+
falls
31
in the 2017 study, what does strength and balance training do?
reduce falls by 35%
32
how is frailty measured?
assessed by the rockwood sore | 1- very fit and 9- terminally ill
33
what year was the study for falls from?
2017
34
what did the 2017 study show relating to falls?
1. that strength and balance training reduced falls by 35% 2. falls are the most common cause of disability and death in the 75+ 3. falls are the most serious and common accident in 65+
35
how does a neck of femur fracture present?
1. pain 2. shortened 3. eternally rotated leg
36
when does NICE recommend arthroplasty after neck of femur fracture?
day of injury, or the day after
37
how many patients does the ncl falls service see yearly?
4000 patients
38
who recommends falls mdt service?
NICE
39
what percentage of people have experienced a synoptic event?
40-50%
40
what groups of people are most likely to experience syncope?
young adults and then over 50+
41
what system/ mechanism describes vasovagal syncope?
Bezold- Jarish Reflex
42
what starts of the chain of Bezold -Jarish Reflex
drop in blood pressure
43
describe the baroreceptor route of vasovagal syncope
1. BP drops 2. drop detected by baroreceptors 3. there is an increase in HR and inotropy via catecholamines 4. there are vigorous ventricular contractions - activates LV mechanoreceptors 5. vasovagal reactions
44
describe the venous return route of Bezold- Jarish Reflex
1. BP drops 2. venous return drops 3. Cardiac Output drops - limited 4. vigorous ventricular contractions - activates LV mechanoreceptors 5. vasovagal reactions
45
what are vasovagal reactions?
decrease in HR and decrease in BP
46
why is syncope an evolutionary flaw?
syncope was to control blood loss by reducing BP and HR - to minimise blood loss, but the body is sensing the signal incorrectly
47
how does syncope present?
myoclonus movements, pale, sweaty, rolling eyes while open, light-headed, black out, restless, strong urge to sit/ lie down
48
what are myoclonus movements?
involuntary jerking movements
49
what is inotropy?
contractions of the heart
50
what is the medial term for blackout?
retinal ischaemia
51
what symptoms to elderly experience through syncope
may not have the signals - no symptoms and therefore they fall more and get injured
52
what are the situational triggers?
pain, cough, deglutination, gelastic, shock, emotion, standing, heat, dehydration, vasodilation
53
what is deglutination
the process of swallowing - situational trigger of syncope
54
what is gelastic
laughing - situational trigger of syncope
55
how do you treat vasovagal syncope?
water, salt, caffeine, physical counter manoeuvres, trigger avoidance
56
how does caffeine help prevent syncope?
it increases bp
57
what is carotid sinus syndrome?
affects older people - no warning | it is the exaggerated response to carotid baroreceptor stimulation
58
how would you treat carotid sinus syndrome?
need to control the response so surgery - pacemaker to control or carotid sinus denervation
59
describe the pathway/ mechanism of orthostatic hypotension
1. go from lying where there is venous pooling in thoracic areas 2. when you stand, gravity pools blood in legs which decreases venous return 3. CO decreases and BP drops 4. baroreceptors end up less stretched 5. medulla detects this and increases HR 6. trying to get CO back up
60
what is the treatment for orthostatic hypotension
water, salt, caffeine, physical counter manoeuvres, compression socks
61
what do systolic and diastolic bp drop by?
systolic drops by 20 mmHg | diastolic drops by 10 mmHg
62
what heart blocks cause syncope
1st does not 2nd does 3rd does
63
what is 2nd degree heart block?
paroxysmal atrioventricular block - sudden change in physiology of AV conduction
64
what is third degree heart block?
ventricular asystole
65
how many people over 60 forget having fallen in last three months?
1 in 3
