100
It decrease active re-absorption of sodium and chloride ions by inhibiting the sodium/chloride co-transporter in the distal convoluted tubule
What is Thiazide ?
100
It collects the venous blood return from the cardinal veins and runs posterior to the LA
What is the coronary sinus ?
100
It is a brief change in voltage (membrane polarisation) across the cell membrane of heart cells and consists of 5 phases .
What is cardiac action potential ?
100
A disease characterised by : an increase in appetite. poor weight gain or loss of weight a sudden growth spurt. smoother skin. fine-textured hair.
What is Graves disease ?
100
8 in 1000
What is incidence of CHD ?
200
It is a phosphodiesterase inhibitor type III which increase the intracellular cAMP leading to net increase in Ca concentration
What is Milrinone ?
200
It is located at the junction of the SVC and RA and initiates the cardiac action potential.
What is the SA node ?
200
It is a benign atrial arrhythmia that occurs when the natural cardiac pacemaker site shifts between the sinoatrial node (SA node) and the atria and is characterised on ECG by at least more than 3 P wave morphologies .
What is (wandering atrial pacemaker) ?
200
It is a type of long term neonatal jaundice, characterized by indirect hyperbilirubinemia that develops after the first 4-7 days of life and has no other identifiable cause.
What is breast milk jaundice ?
200
it is a measurement of all individuals affected by the disease at a particular time
What is (Prevalence) ?
300
It acts by inhibiting cell membrane sodium/potassium ATPase which leads to reversal of the usual sodium/calcium exchange. An increased intracellular calcium level results which, in myocardial muscle, has the effect of enhancing the strength of contraction
What is digoxin ?
300
It transports deoxygenated blood from the posterior walls of the thorax and abdomen into the superior vena cava vein
What is the azygos vein ?
300
It is a disorder characterized by sudden death associated with one of several ECG patterns characterized by incomplete right bundle-branch block and ST-segment elevations in the anterior precordial leads
What is Brugada syndrome ?
300
sandpaper skin rash
What is the description given to the rash associated with scarlet fever ?
300
It is the probability that subjects with a negative screening test truly don't have the disease
What is negative predictive value ?
400
Its used to treat SVT if vagal manoeuvres fail.
What is adenosine ?
400
It is a smooth-surfaced, thick portion of heart muscle in a crescent shape at the opening into the right atrial appendage
What is crista terminalis ?
400
It is a syndrome associated with long QT interval on ECG and severe, bilateral sensorineural hearing loss .
What is Jervell and Lange-Nielsen syndrome ?
400
A disease characterised by the following : high fever that persists for five or more days rash bloodshot eyes, without crusting bright red, swollen lips “strawberry” tongue, which appears shiny and bright with red spots swollen lymph nodes swollen hands and feet red palms and soles of the feet
What is Kawasaki disease ?
400
It is the hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.
What is Null hypothesis ?
500
It shows beta blocker-like and calcium channel blocker-like actions on the SA and AV nodes, increases the refractory period via sodium- and potassium-channel effects, and slows intra-cardiac conduction of the cardiac action potential, via sodium-channel effects
What is amiodarone ?
500
The nerve that typically arises from the vagus nerve just anterior and caudal to the ductus arteriosus .
What is recurrent laryngeal nerve ?
500
It is a small positive deflection (‘blip’) buried in the end of the QRS complex. It is the characteristic finding in arrhythmogenic right ventricular dysplasia (ARVD)
What is Epsilon wave ?
500
A disease encompasses a group of autosomal recessive disorders, each of which involves a deficiency of an enzyme involved in the synthesis of cortisol, aldosterone, or both
What is congenital adrenal hyperplasia (CAH) ?
500
It is the commonest congenital cardiac abnormality with an estimated prevalence of 1-2%
What is BAV ?
