1

Implantable Cardioverter Defibrillators are first line treatment for Hypertrophic Cardiomyopathy

1

Arrhythmogenic right ventricular cardiomyopathy is an autosomal dominant condition whereby mutations in the genes encoding cardiac cause fibrofatty replacement of cardiomyocytes in the right ventricular, thus leading to arrhythmias.

1

Generally, which of the following types of medication has been proven to reduce the rate of Sudden Cardiac Death?

1

The likelihood of having a disease if you have a gene mutation is called the of a disease

1

Marfan Syndrome occurs due to a mutation to the gene

1

The safest position for a baby to sleep in is on their side.

1

You are receiving patients in casualty. A 38 yo healthy man became acutely unwell, becoming very pale and than grey and unresponsive. An ambulance was called, but in the interim, he spontaneously recovered. He has no past medical history.
On arrival in hospital, his ECG was as follows:

What is the most likely diagnosis?

1

What is the only type of shock which causes a bradycardia (as opposed to tachycardia)?

1

Which of the following should be given to treat neurogenic shock?

1

Inadequate organ perfusion caused by the failure of the heart to act as a pump is known as shock

1

Anaphylactic shock is treated via IV

1

Anaphylactic shock is treated with 500micrograms of adrenaline at a dilution of

1

A patient is hypertensive once their BP drops below ( 90/60, 90/70, 100/60, 100/70 )

1

In neurogenic shock, the ( sympathetic, parasympathetic ) supply to the heart has been cut off which is which neurogenic shock results in ( bradycardia, tachycardia ) (when the other types of shock result in ( tachycardia, bradycardia ))

1

MI, Heart Failure, PE and Cardiac Tamponade are all causes of which type of shock?

1

Which of the following is most commonly known to cause cardiac arrest?

1

Which two of the following are typically used to treat cardiogenic shock?

1

Which of the following are types of distributive shock?
I.e. the blood volume is normal, it is just unevenly distributed

1

At what depth should chest compressions be conducted?

1

In a case of an adult with heart failure, rescue breaths should be conducted before chest compressions are started.

1

Which of the following are shockable?

1

Which of the following are non-shockable rhythms?

1

IV Adrenaline (+IV Amiodarone if arrhythmia) should be given after ( 3, 5, 10 ) rounds of CPR and every ( 3, 5, 10 ) rounds thereafter

1

❌ is reversible
❌ is irreversible

Clinical death

Biologic death

1

In absence of CPR, clinical death lasts around 3-6 minutes before biologic death occurs.
