Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

• Evaluate the need for calibration and quality assurance for all measurements undertaken in Cardiac Physiology
• Recognise and evaluate limitations of non-invasive investigations.
• Become informed recipients of research evidence in healthcare science by critically appraising professional journals and associated literature using established appraisal tools
• Interpretation of non-invasive diagnostic investigations.
• Explain the principles of a range of routine non-invasive diagnostic cardiac investigations used to detect and quantify cardiac disease, and compare and contrast each modality. a) 12 lead Clinical Electrocardiography b) Ambulatory electrocardiography application and analysis c) Blood pressure measurement d) Ambulatory blood pressure monitoring & analysis e) Cardiac stress testing procedures f) Transthoracic echocardiography

In this module students will build on Year 1 learning and begin detailed learning that underpins the routine practical techniques.

Communication skills and team working

Students will learn by exploring material in seminars and laboratory practicals in conjunction with directed learning. Students will be encouraged to take responsibility for the development of their own learning by utilising a variety of means such as multimedia resources, and the library, and by self-directed development of the study skills necessary to access these resources.

Formative

This is how we’ll give you feedback as you are learning. It is not a formal test or exam.

Critical article and verbal presentation

• Assessment Type: Formative
• Feedback: Feedback will be provided from a panel on presentation skills and the critical review of the article.
• Final Assessment: No
• Group Work: No

Summative

This is how we’ll formally assess what you have learned in this module.

Referral

This is how we’ll assess you if you don’t meet the criteria to pass this module.
