Q

what is 2nd degree - mobitz type 1 heart block

A

progressive prolongation of the PR interval on consecutive beats followed by a blocked P wave (i.e., a dropped QRS complex)

It usually does not cause symptoms and rarely requires treatment.

Q

what is 2nd degree - mobitz type 2 heart block

A

P wave is blocked from initiating a QRS complex like type 1 but there is no pattern

constant PR interval
p wave without a QRS

needs intervention i.e. pacemaker

A

First line: ACE-inhibitor and β-blocker

Second line: mineralocorticoid antagonist (spironolactone)

Add-in ARB if ACI-inhibitor intolerant

Third line: Digoxin

If fluid overloaded: Furosemide

Q

what is definition of HTN

A

Blood pressure > 140/90

Ambulatory BP monitoring can aid diagnosis

  • Rules out white coat hypertension
  • Stage 1: ABPM >135/85 -> calculate CV risk, if >20% TREAT!
  • Stage 2: ABPM >150/95 -> treat

Q

treatment cascade for BP

A

Step 1:
If under 55
- start on ACEi (A)

If over 55
- start on CCB (C)

Step 2:
A + C

Step 3:
A + C + D

Step 4:
A + C + D = consider further diuretic or alpha/beta blocker
Consider seeking expert advice

Q

what are the 3 categories of ACS

A

Unstable angina: ECG changes, no corresponding trop rise

NSTEMI: ECG changes (ST depression, T wave inversion), trop rise

STEMI: ST elevation, trop rise
>2mm in 2 adjacent chest leads
>1mm in 2 adjacent limb leads
New LBBB

Q

STEMI Tx

A

Primary PCI within 2 hours of presentation

Thrombolysis if PCI not available

MONAC acronym is not longer accurate, instead:

  • IV morphine (plus anti-emetic)
  • Oxygen ONLY if sats <95%
  • GTN spray
  • Aspirin 300mg
  • Ticagrelor 180mg or Clopidogrel 75mg

Q

Tx for NSTEMI

A
  • IV morphine (plus anti-emetic)
  • GTN spray
  • Aspirin 300mg
  • Clopidogrel 300mg
  • Fondaparinux
  • Angiography +/- PCI
20
Q

side effects of ACE-i

A

Dry cough

[switch to ARB]

21
Q

side effects of GTN spray

A

headaches

22
Q

side effects of bisoprolol

A

Dizziness/postural hypotension/collapse

Stop if this occurs – the risk of harm outweighs benefit

23
Q

what drugs cause Long QT syndrome

A

Antibiotics (Erythromycin, Clarithromycin, anti-fungals)

Antipsychotics (Haloperidol, Quetiapine, Risperidone)

Antiarrhythmics (Amiodarone)

Antidepressants (Citalopram, Amitriptyline, Clomipramime)

Antiemetics (Ondansetron, Domperidone)

Others (Methadone, antimalarials, antiretrovirals)

24
Q

A 55 year-old man presents to his GP for a routine health check. He is found to have BP 160/105 in clinic. He has a strong family history of cardiac disease, and a personal history of type 2 diabetes. He is a current smoker. What is the most appropriate management?

A

Start lisinopril and encourage smoking cessation

Diabetic = ACE-inhibitor is first line

25
Q

how is pericarditis treated

A

high-dose ibuprofen (or any NSAIDs)

26
Q

An 80 year old inpatient in a surgical ward develops acute shortness of breath, with RR 28 and SpO2 85%. They are tachycardic and normotensive. Temperature is 38.4. They are day 2 post-op for bowel obstruction. Past medical history includes a STEMI 6 months previously, and 3 months of worsening shortness of breath on exertion at home before admission. What is the most appropriate initial management?

A

High-flow oxygen

This could be acute pulmonary oedema, PE or chest infection. No matter which, if a patient has low sats -> give O2!

27
Q

treatment for SVT

A

Adenosine

28
Q

A 69 year-old is reviewed in the heart failure clinic. They have increasing shortness of breath on exertion, and reduced exercise tolerance. Currently they can walk 20m before having to stop to catch their breath; 6 months ago they could walk half a mile. Past medical history includes 2 previous MIs, angina, moderate LVSD (confirmed on echocardiogram 2 months ago), T2DM, and benign prostatic hyperplasia. They are on bisoprolol, ramipril and tamsulosin. What is the most appropriate next management step?

A

Start spironolactone

After BB and ACE-inhibitor, adding MRA is the next step in chronic LVF

35
Q

ECG changes - hypocalcaemia

A
