Cardiology Flashcards
If a patient presents with bradycardia, what should you look for?
Adverse Features
What are the four adverse features
HF
Myocardial ischaemia
Shock
Syncope
If a patient has bradycardia with adverse features what should you do
IV atropine 500mcg
What dose of atropine is given
IV 500mcg
If a patient with bradycardia has a satisfactory response to 500mcg IV atropine what is done
Assess if they are at-risk of asystole
What 4 factors make a patient at-risk of asystole
- Recent asystole
- Ventricular pause >3s
- Mobitz II AV block
- Complete HB, Broad QRS
If a patient is not at risk of asystole what is done
Observe
If a patient is at-risk of asystole what is done
Repeat IV atropine 500mcg IV
what is the maximum dose of atropine that can be given
Up to 3mg
what happens if there is not a satisfactory response to atropine
Repeat up to 3mg IV
what is an alternative approach to repeating atropine
Transcutaenous Pacing
what other drugs can be given as an alternative to atropine
Adrenaline
Isoprenaline
what is the mnemonic to remember STEMI management
MONARTH
what is given in a STEMI
Morphine, Metclopramide Oxygen GTN Aspirin Reperfusion Ticagrelor Heparin
what dose of morphine is given
5mg IV morphine (4-hourly)
what should be given with IV morphine
IV Metclopramide
what dose of metclopramide is given
10mg
what dose of GTN is given
500mcg sublingual
how often can GTN spray be repeated
every 5-minutes
what is the maximum dose of GTN spray that can be given
3 doses
what loading dose of aspirin is given
300mg PO
what is the long-term dose of aspirin
75mg OD
what is the loading dose of ticagrelor
180mg PO
what dose of fondaparinux is given
2.5mg SC
when should fondaparinux be stopped
Continue for 8-days. Stop 24h before CABG surgery if intended
when is PCI attempted
- STEMI on ECG
- Can reach reperfusion centre in 120min
if PCI is not available what is performed
Fibrinolysis
what is used for fibrinolysis
Tenectaplase
what time frame should tenectplase be implemented
WITHIN 6-HOURS OF SYMPTOMS
how is tenectplase given
30-60mg over 10s
what should be ordered after tenectplase
ECG
what are you looking for on post-tenectplase ECG
50% resolution in ST elevation
if there is not 50% reduction in ST elevation, what is done
Rescue PCI
how is a patient with NSTEMI initially managed
Initial drug-management
what is included in the initial drug-treatment of NSTEMI
IV morphine, IV metoclopramide Sublingual GTN Aspirin (300mg) Ticagrelor (180mg) Fondaparinux (2.5mg)
what dose of morphine is given
5mg IV
what dose of sublingual GTN is given
500mcg
what dose of aspirin is given
300mg
what dose of ticagrelor is given
180mg
when is fondaparinux not given
Do not give unless angiography in next 24h is planned
after initial management of NSTEMI what is performed
