A 28 year old male patient visits the GP surgery complaining of palpitations. During initial assessment you find that his BP is 185/120. You organise a 24 PB monitoring and send off a blood sample for FBC, glucose, U&Es. His K comes back as 3.5 mMol/l (normal 4.5-5.5 mMol). The patient at this point is on no medication. What is the most likely cause of his hypertension?
A. Renal artery stenosis
B. Policystic kidney disease
C. Pheochromocytoma
D. Hyperaldesteronism
E. Hyperthyroidism
D. Hyperaldesteronism
Of the list below which event is unlikely to happen in heart failure?
A. A compensatory increase in sympathetic tone
B. A decreased parasympathetic innervation to the heart via the vagus nerve.
C. An increase in renin production
D. An increase is ANP/BNP levels
E. A compensatory decrease in circulating volume
E. A compensatory decrease in circulating volume
In a patient with a complete occlusion of the LAD where would you expect to see the most pronounced ST elevation?
In v2, v3, v4
A 68 year old female patient is brought to A&E by ambulance. She has experienced chest pain for the last half an hour, is pale and clammy. On the 12 lead ECG the QRS complexes are wide (more than 200 milliseconds). There is a deep QS wave in v1-v4 and the QRS in M shaped in v5-v6. What is the reason for this?
A. Ventricular tachycardia
B. A Mobitz type I block
C. Right bundle branch block
D. Left bundle branch block
E. Wolff-Parkinson-Wight syndrome
D. Left bundle branch block
A patient has a coronary plaque. The fibrous cap has been eroded and the lipid core is exposed to the blood flow. On top of the plaque there is a platelet clot forming that almost occludes the artery but from time to time bits of the thrombus brake off keeping the lumen patent. What condition is compatible with the above picture?
NSTEMI
A 39 year old anxious male patient present with to A&E with chest pain. The pain started about 2 hours ago and is of variable intensity and does not radiate. The patient has a fine tremor, is pale and tachycardic. Otherwise the observations are unremarkable. However, on the ECG there is a slight ST elevation in v1-v3. This may be a normal variant. How would you investigate this patient further?
A. Given the atypical presentation and the age reassure him and send him home.
B. Organise an exercise test
C. Use high sensitivity troponin testing at 1 and 3 hours to rule out cardiac hypoxia.
D. Do a stress echocardiogram
E. Organize a CT angiogram
C. Use high sensitivity troponin testing at 1 and 3 hours to rule out cardiac hypoxia.
Which ion channel/pumps in cardiomyocytes is blocked by local anaesthetics?
Voltage gated Sodium channel
Which ion/channel in cardiomyocytes is blocked by drugs causing pharmacologically acquired long QT-syndrome (LQTS)
Voltage gated Potassium channel
Which common valvular heart disease would result in a systolic crescendo-decrescendo murmur?
Aortic stenosis
Which phase of the ECG corresponds to the beginning of the rapid passive ventricular filling?
A. The period between the T and the P wave
B. The PQ interval
C. The QRS complex
D. The ST segment
E. The T wave
D. The ST segment
Name the mediator that when activated causes a reduction in the circulating volume:
A. Adrenalin/noradrenaline
B. Endothelin
C. Bradykinin
D. BNP
E. Histamine
D. BNP
This medication inhibits the Na++/K+/2Cl- carrier in thick ascending limb of the loop of Henle.
A. Glyceryl Trinitrate
B. Furosemide
C. Bendroflumethiazide
D. Hydralazine
E. Indapamide
B. Furosemide
Of the events described below which one happens as a result of angiotensin 2 production?
A.The activation of the baroreceptors in the carotid artery
B. An increase in the sympathetic innervation of the kidney.
C. Increased vasoconstriction of the efferent arterioles
D. Increased vasoconstriction of the afferent arterioles
E. The activation of the low pressure baroreceptors in the atria/ventricles.
C. Increased vasoconstriction of the efferent arterioles
A 23 year old female patient is 6 months pregnant. She lives on the 6th floor of a council high-rise building. She presents to the GP because the previous day, when the lift was broken, she experienced central gripping chest pain as she was climbing the stairs. She is known to have a systolic murmur. She is referred to cardiology where a Doppler ECHO finds severe aortic stenosis. What is the cause of of the chest pain?
A. Due to the increased pressure the semilunar valves cover up the openings of the coronary arteries.
B. Her heart rate is so high that diastolic flow in the coronary arteries is compromised.
C. Due to the pregnancy pressing on the iliac veins her preload is too low.
D. The stenotic valve results in high blood pressure in the aorta
E. Her circulating volume is increased, increasing oxygen demand in the myocardium.
E. Her circulating volume is increased, increasing oxygen demand in the myocardium.

A. Lidocaine
B. Fleicanide
C. Verapamil
D. Digoxin
E. Bisoprolol
E. Bisoprolol
