management of paroxysmal AF
rhythm control = flecanide prevention = BB, stall or amiodarone anticoag assessment via CHADS2VASC
209
treatment of AF if persistant
rhythm control | rate control
210
rhythm control for AF
``` ECHO first to look for structural abnormalities anticoagulation sotalol BB amiodarone ```
211
rate control for AF
BB or rate limiting CCB add digoxin (not as mono therapy) amiodarone
212
what happens if BB and CCB togtehr
bradycardia
213
invasive options for AF tx
radio frequency ablation, maze procedure, pacing
214
anticoagulant options in AF
warfarin or NOAC if >1 CHADS
215
what is cha2ds2vasc
``` congestive heart failure HTN age >75 DM stroke/vte/TIA vascular disease >65 female ```
216
what is hasbled
used to assess bleed risk in those on anticogulants in AF
217
contraindications of flecainde
strutural defects in the heart
218
management of flutter
like AF | amiodraone to restore sinus
219
examples of narrow complex tachycardias
AF, flutter, atrial tachycardia, AVRT, AVNRT
220
medications to avoids in WPW
BB, CCB, adenosine, digoxin as leads to VF
221
what is WPW
congenital accessory conducting pathway between atria and ventricles
222
treatment of WPW
radio frequency ablation of the accessory pathway amiodarone sotalol NOT DIGOXIN
223
acute management in narrow complex tachycardia (supraventricular tachycardia) with no regular rhythm
treat like AF
224
acute management in narrow complex tachycardia (supraventricular tachycardia) with regular rhythm
ECG vagal manoeuvres adenosine 6mg IV, then 12mg then 12mg if no relief, and no adverse signs then give digoxin, amiodarone, verapamil or atenolol, if no relied, DC
225
why not digoxin in WPW
as reduces ventricular rate but increasing conduction through bundle of his
226
treatment of VT with pulse and no adverse signs
correct electrolytes regular = amiodarone irregular = AF tx failure = DC
227
treatment of VT with pulse and adverse signs
DC x 3 then amiodarone then ICD
228
cause of VT
recent MI
229
treatment of VF
``` dc dc adrenaline dc amiodarone ``` longterm = BB +ICD if witness = 3xDC then CPR
230
treatment of tornadoes de pointes
mgso4 | then BB and ICD
231
complication of tornadoes de pointes
can lead to VF
232
what is brugada
ad inheritance | defective sodium channel leading to restricted movement of sodium channel
233
treatment of brugada
if abnormal ECG - defibrillator
234
what should be avoided in brugada
phenytoin, TCAs, illicit drugs, high temp, low K+
235
how to enhance ECG change in brugade
give flecanide as it is a sodium channel blocker
236
management of pulseless electrical activity
``` CPR airway monitor adrenaline 1ml in 10,000 Iv central line every 3-5 minutes CPR once shockable rhythm DC CPR adrenaline DC amiodarone ```
237
causes of bradycardia
``` sinus heart block drugs vagal hypertonia hypothyroidism dilated cardiomyopathy ```
238
treatment of bradycardia
atropine IV adrenaline external pacing permanent pacing
239
management of AAA
``` O2 large bore cannula major haemorrhage protocol vascular surgeon before rupture analgesic ``` if <5.5 then monitor via US
240
symptoms of ruptured AAA
sudden onset severe abdo pain collapse and shcok expansible abdo mass
241
investigations of AAA
AXR abdo US CT/MRI angiography
242
stages of limb ischaemia
intermittent claudication critical limb ischaemia leinches syndrome burgers disease
243
6ps of peripheral vascular disease
pain, pulseless, perishingling cold, paraestheisa, paralysis, pale
244
symptoms of limb ischaemia
raised CRT, ulcers, nail dystrophy, skin 6ps, venous guttering, burgers angle/sign
245
what is the fontaine classification
asymptomatic intermittent claudication ischaemia rest pain ulceration and gangrene
246
investigations in critical limb ischaemia
``` doppler waveforms ABPI walk test bloods imaging - colour duplex US, CT/MR angiogram contrast ```
