Non-Invasive Cardiac Physiology

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

• Appreciate the need for effective communication skills and respect for the rights, dignity and privacy of patients.
• Explain the principles of a range of routine non-invasive diagnostic cardiac investigations 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 e) Cardiac stress testing procedures (including echocardiography)
• Evaluate the need for calibration and quality assurance for all measurements undertaken in Cardiac Physiology
• Become informed recipients of research evidence in healthcare science by critically appraising professional journals and associated literature using established appraisal tools
• Interpretation of electrocardiograms including arrhythmias and morphological abnormalities.
• Recognise and evaluate limitations of non-invasive investigations.

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

Teaching and learning methods

Students will learn by exploring material in seminars and laboratory practical's 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.

Assessment strategy

Both components of the summative assessment must be passed

Formative

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

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.
