G6.i · Cardiovascular Measurement

This VIVA will examine cardiovascular physiology and monitoring. Relate the parts of the cardiac cycle and ECG to the CVP waveform below? (Image removed from report.)

This viva will examine the electrocardiogram and local anaesthetic pharmacology. Label the components of the ECG trace and explain the x and y axis. (Image removed from report.)

This viva will explore your knowledge of anti-arrhythmic agents and the electrocardiogram. Briefly describe the phases of an action potential of the SA nodal / pacemaker cell. (Image removed from report.)

This viva is about the ECG and important electrical currents in the heart. Relate the phases of the ventricular myocyte action potential to the normal ECG. (Image removed from report.)

This viva will explore your knowledge of the following areas: Renal clearance and aspects of the ECG. What is meant by the term clearance when applied to the kidney? What are the units?

This viva is on cardiac electrical physiology and anti-arrhythmic drugs. This is a normal trace obtained from the Lead II of the electrocardiogram. Describe the features of this trace. (Image removed from report.)

This Viva tested knowledge of cardiovascular physiology, ECG and Antiarrhythmic pharmacology.

This Viva explored knowledge of the principles of the electrocardiography (ECG) and statistical tests. Specifically it tested knowledge of the recording of the normal ECG, sources of error and statistics (sensitivity, specificity, prevalence, etc.). Most candidates performed well, with knowledge of sources of error in the ECG and the measures of performance of a diagnostic test being an area of weakness.

This Viva will test your knowledge of renal physiology and potassium regulation Q 1. Briefly outline the functions of the kidney? This viva tested, briefly, knowledge of renal function, as well as covering hyperkalaemia in some depth. Candidates had a general knowledge related to hyperkalaemia, but struggled to explain the cardiac consequences as they related to the cardiac action potential and as they reflected upon the ECG.

The initial information given to the candidates was – This will explore your knowledge of cardiovasclar physiology. Draw a normal ECG tracing , indicate waves and intervals And Statistics Candidates were asked to draw a normal ECG trace and to explain the ionic mechanisms that form the basis to that trace and the consequences of hyperkalaemia. In relation to statistics, candidates were shown a series of blood pressure values on a range of patients, asked to describe what type of data was being represented, how it may be displayed, what is normal distribution and what test may be used to compare the blood pressure values between the two groups. It is important for candidates to understand that generally only knowledge of fundamental, common and fairly simple statistical tests would be asked from them.

Please explain the physiological basis of the electrocardiograph.
