26
What is the diagnosis and management if a pt presents with SOB, chest pain, worse on coughing and a STEMI 3 weeks ago
Pericarditis/Dressler's syndrome
27
What is seen in a JVP with complete heart block?
Cannon A-wave (atrial contraction against closed tricuspid valve)
28
After what conditions is Mobitz type 2 likely to present?
MI, mitral valve repair, rheumatic heart disease
29
What are some causes of first degree heart block?
athlete, MI, electrolyte disturbance, B-blocker, CCB, digoxin
30
What treatment is given in orthostatic hypotension?
Fludrocortisone and midrodrine (increase renal Na+ reabsorption)
31
What can be given within 6 hours after an inferior STEMI?
IV tenecteplase (fibrinolysis), PCI is done within 2 hours
32
What is the management for fast AF?
``` DC cardioversion (due to adverse features, e.g. syncope, HF, myocardial ischaemia and shock) B-blocker if there are no adverse features ```
33
What are the signs of aortic stenosis?
Ejection systolic murmur, radiates to carotids on inspiration, narrow pulse pressure, slow rising pulse, syncope, angina, dyspnoea Severe: peak trans-valvular pressure gradient over 40 mmHg
34
What 3 things could a pan-systolic murmur be?
Mitral regurgitation - loudest at apex, radiates to axilla, loudest on expiration Tricuspid regurgitation - loudest at left sternal edge on inspiration Ventricular septal defect - loudest at left sternal edge, common in Down's
35
What is the main causative agent for infective endocarditis?
Staphylococcus aureus, found on skin, can enter through IV needles
36
What is a side-effect of statins?
Rhabdomyolosis - pain/swelling, brown urine, AKI
37
What is torsades de pointes and what is the treatment?
Ventricular tachycardia, prolonged QT | Treatment - IV magnesium sulphate, stop causative medications, haemodynamically unstable - defib

What are the causes and signs of aortic regurgitation?
Rheumatic fever, pancarditis, fibrosis, stenosis, regurgitation of valves Signs: SOB, fatigue, signs of HF, wide pulse pressure, CVS collapse

What is amyloidosis and what does it cause?
Amyloid protein deposition - heart, restrictive cardiomyopathy, HF w/ preserved EF Arrhythmia, conduction disturbances, nephrotic range proteinuria = oedema
57
What are the contraindications for GTN?
Low BP, GTN decreases it further, can cause cardiac arrest
58
What are the 2 most common causes of infective endocarditis?
Staph aureus, Strep viridans

How is pulmonary HTN diagnosed?
Right heart catheterisation, pulmonary pressures
60
What is the best combination for B-blocker and CCB?

61
What complication can rhabdomyolysis lead to?
Hyperkalaemia -> arrhythmia e.g. VT
62
What JVP waveform is seen in tricuspid regurgitation?
Prominent V-wave
