About the Course
This experiential VR training and assessment is designed to help learners acquire the necessary skills to use and understand an electrocardiograph.
An electrocardiograph is an instrument that allows the heart’s electrical activity to be recorded and studied. It is used to produce an electrical (electro) tracing (graph) of the heart (cardio). This representative tracing of the electricity, as it moves through the heart, is known as an electrocardiogram (ECG). The ECG procedure may not be difficult to perform but surely requires competence and accuracy. Each electrical current of the heart must be precisely traced as this is what helps in deciding the course of care and treatment. Even a slight mistake may result in an inaccurate reading and lead to the wrong medication or treatment.
This interactive electrocardiography VR course takes place in a realistic, zero-risk virtual environment where learners can use physics-based interactions to practice the procedure on a virtual patient. In training mode, the step-by-step guides enable a scaffolded learning experience, while the assessment mode provides the user with immediate feedback as mistakes are made. The user can only pass the assessment if the entire procedure is performed in the correct sequence without mistakes. Learner performance can be tracked through an advanced analytics portal, empowering administrators to manage compliance, identify areas for improvement, and gain a deeper understanding of their learners.
- Attain the foundational skills required to use an ECG machine
- Understand how to interpret ECG output
Leads & Waveforms
The 12-lead ECG, which records the electrical activities of the heart, makes use of electrodes and lead wires to complete the process. Lead wires are connected to electrodes, small sensors, on one end and the ECG machine on the other. The electrodes are placed on the skin to read the electrical activities, which are transmitted to the ECG machine through the lead wires. Though named 12-lead ECG, 10 lead wires are used for the purpose. In this VR training, you will reinforce your knowledge about the 12-lead ECG system and how the electrical activity works across various leads. Apply theoretical knowledge in a practical scenario with a virtual patient and various interactive tools. We have designed the interactions in a way that helps learners visualize the directions of currents produced by various combinations of leads.
Operating the ECG Machine
Speed, gain and artifact filter are the three most important controls on the electrocardiograph. This VR training program is designed to help the learner understand these controls on the electrocardiograph. Interacting with the machine, gaining familiarity with its functions and performing steps to generate the correct output of the graph is designed to assist in building confidence. A confident ECG operator can help to put an anxious patient at ease, thereby making the process more smooth and comfortable. Learners may also gain practical knowledge of the practical implications faced while dealing with a patient.
Performance of an ECG
To perform a successful ECG procedure, it is important to have solid knowledge of where and how to place the electrodes on the chest and limbs as well as to understand the significance of the limb leads. ECG readings need to be accurate and precise. The precision of readings gained from this procedure is particularly important when it comes to patients suffering a cardiac crisis. Placing electrodes at the wrong places will produce an incorrect result or no graph in the output. This VR training, with the use of virtual humans, provides learners with an immersive experience to help them practice and perform the lead placements accurately as well as connect the correct lead wires for a successful ECG procedure.
An ECG analysis is a combination of five-steps to gather data about the core components of the ECG rhythm strip. These components consist of Rhythm (regularity), Rate, P wave morphology (shape), PR interval, QRS duration and morphology. In the immersive environment of this VR training session, learners master the five-step process of gathering data, perform interpretations and get skilled in rhythm classification. Learners will be presented with an output graph of the ECG and they may select and highlight the correct region on the graph.
For every patient, a normal sinus rhythm is desired. A patient with a normal sinus rhythm should have a normal cardiac output. Cardiac output (CO) refers to the volume of blood the heart pumps each minute. Stroke volume is the volume of blood ejected by one or both ventricles with each contraction. CO is determined by using the equation Heart Rate (HR) * Stroke Volume (SV). This VR session will help learners become proficient in identifying various sinus rhythms originating from the sinus node by analyzing the rhythm strips. This competency is extremely helpful to improve the analytical skill, interact with the graphs and identify the correct rhythms produced.
The AV junction includes the atrioventricular (AV) node and the surrounding area. With junctional rhythms it is worth noting that the electrical currents originate from the AV junction and not the SA node. Due to this reason the electrical impulses that result in depolarization of the atria flow in the reverse direction. This backward flowing electrical impulse leads to the formation of an inverted P morphology which is seen in junctional dysrhythmias. This VR session is designed to help learners’ practice and get skilled in identifying these formations, P wavelength and its relation to the QRS complexes.
