Patient & Catheter Setup, Model And Fusion.

In Model Workflow - Model Edit Mode with multiple surfaces in the Surface List and one selected, the user can perform various actions. They can edit the surface names, color, detail type, and fill value for the selected surface. Additionally, they can also change the surface color, grid, and visibility of a surface that is not selected. The user has the option to include or uninclude all the surfaces present in the Surface List. Furthermore, they can delete existing model points of the selected surface. Lastly, the user can finish the model.

The different ways of adding catheters to a study include loading a catheter preset, loading a template which has all the presets saved with it, loading a template which has only the catheter preset saved with it, and manually defining a catheter or adding from a catalog.

An unsuccessful study resume can occur when trying to resume the study with a segment paused at a location where there is no valid location data. Additionally, it can also happen when the Amplifier is not connected to the study while resuming.

The explanation for the correct answer is that DIF stands for Digital Image Fusion, which is a technique used to combine multiple images into a single image. DIF files can be loaded in all the five workflows (Setup, Model, Mapping, Therapy & Review), which means that they can be used throughout the entire process of the study. This allows for seamless integration of the DIF files into the various stages of the study.

The correct statements related to Field Scaling are: Unincluding all the surfaces in the Surfaces List unapplies the Field Scaling. Field Scaling are of two types NavX & Magnetic (NavX SE / MediGuide depending on the study). Field Scaling can fail when there are no enough model points and magnetic fiducials (in NavX SE & MediGuide study) are collected.

Model points can be collected on a Contact Force catheter when the Total Force is outside the Threshold. While model point collection is in progress for a catheter, it is possible to change the catheter source for model point collection. Model point collection stops when the user collects Respiration Data. Even when there is no valid Magnetic data for Sensor Enabled catheters, Model Points can be still collected with valid impedance data. The statement suggests that model points can be collected on a Contact Force catheter when the total force exceeds the threshold, the catheter source can be changed during model point collection, model point collection stops when respiration data is collected, and model points can still be collected with valid impedance data even if there is no valid magnetic data for Sensor Enabled catheters.

The valid Electrode Spacing values for a 7 electrode catheter are 5 -10 -5, 1.35 - 2.49 - 1.35, and 999 - 10 - 999 - 65 - 45 - 65. These values are consistent with the requirement of having 7 electrodes and provide the necessary spacing between them.

The given correct answer states that an Array Study supports both Array and EP Catheters, while the Sheath Detection feature is not supported in an Array Study. This means that an Array Study can be used with both types of catheters, but it does not have the ability to detect the sheath.

The statement is stating that the Measured Electrode Spacing is only calculated when the EnSite Model is Field Scaled and it changes with Automatic Field Scaling. In other words, the spacing between the electrodes is determined and adjusted based on the scaling of the EnSite Model. Therefore, the answer "True" indicates that the statement is correct.

The study cannot be ended without entering the First Name & Physician details because these are crucial pieces of information that are likely required for documentation and identification purposes. Without these details, the study may lack important information and could potentially be considered incomplete or invalid. Therefore, it is not true that the study can be ended without entering those information.

The correct answer is "All of the above is CORRECT". This means that all of the filtering options listed (i, ii, iii, iv, v, vi, vii, and viii) are the correct ways to filter the catheters in the Catheter Catalog.

After performing the given sequence of steps, the observation(s) that occur are as follows:
- The Active Electrode is set to '2' and it is displayed in Green in the Map Display.
- The Active Electrode is set to 'D' and it is displayed in Green in the Map Display.
- The Roving Source Electrode of the Detection Settings is set to 'D'.
- The Roving Source Electrode of the Detection Settings is set to 'All'.
- Signals -D +2 , -3 +4 , -5 +6 are present in the Map Display.
- Signals -D +2 and -- +4 are present in the Map Display.

The statement is false because while selecting 'Type' from the Catheter Catalog, Diagnostic and Ablation cannot be chosen simultaneously. These are two different types of catheters used for different purposes. Diagnostic catheters are used for diagnostic procedures such as mapping and recording electrical signals in the heart, while ablation catheters are used for ablating or destroying abnormal tissue in the heart. Therefore, they cannot be chosen at the same time.

When a map is loaded onto a model that is initially created in 'Red' color, the color of the model will change to 'Off White'.

An Array catheter consists of 64 electrodes.

In an EnSite Model created with a bunch of surfaces in an Array Study, the first surface cannot be deleted. This suggests that the app has a restriction in place that prevents the deletion of the first surface in an Array Study.

The active electrode after performing the sequence of steps will be the distal electrode of the HRA catheter. This is because the question states that the 2nd and 4th electrodes of the HRA catheter are disconnected, leaving only the distal electrode as the active electrode.

The statement ii is true because the user is provided with a confirmation pop-up before deleting a catheter. The statement iii is true because a manually added catheter can be added to the Catheter Catalog anytime during the study. The statement v is true because the signal order of a catheter can be changed anytime during the study. Therefore, the correct option is ii, iii & v is TRUE.

The WorkMate Claris Catheter Input Module along with Genconnect can visualize 124 Electrophysiology catheter electrodes at once.

The given statement is true because Fusion Fiducials, which are markers used in medical imaging to aid in the alignment of different scans, can indeed be edited or deleted at any time during a study. This flexibility allows for adjustments to be made as needed, ensuring accurate and precise alignment of the scans.

After performing the given sequence of steps, the number of surfaces present in the study will be 5. This is because initially there is one surface in the basic setup. Then, 3 surfaces are created from 3 different catheters, making the total number of surfaces 4. After finishing the model, 2 more surfaces are created from 2 different catheters, resulting in a total of 6 surfaces. However, when the changes are discarded and confirmed, the number of surfaces is reduced back to 5.

When an EnSite Model is created for a patient with less weight, such as 20kg, the model expands in size after field scaling. This means that the model will be larger than the actual size of the patient.

When the user attempts to discard the changes and confirms the action during a model edit mode, the app actually exits the model edit mode and discards the changes. Therefore, the given statement is false.

The given answer states that statements i, ii, and iv are correct, while statement iii is incorrect. According to statement i, when the distal electrode of a catheter is invalid, all the electrodes of that catheter turn 'RED' and points North. Statement ii states that electrodes are displayed in 'YELLOW' when they receive data from an unreliable location and when there are Packet patching, drop, and delay errors. Statement iv mentions that the active electrode is displayed in GREEN in NavX study and it blinks GREEN in an Array Study. Therefore, based on these statements, the correct answer is i, ii, iv is CORRECT, and iii is INCORRECT.

The correct answer is -3 +4 , -2 +3 , -D +2, -3 +D. This is the correct order of signals after performing the given sequence of steps. The first step adds a 4 electrode catheter with polarity 'All Bipole'. The second step changes the signal order to 'Proximal to Distal'. The third step adds a trace "-3 +D". Combining these steps, the correct order of signals is -3 +4 , -2 +3 , -D +2, -3 +D.

According to the given statements, i, ii, and iv are true, which means that "None" is selected by default before validation, the first visible catheter is selected after validation, and if an active EnGuide is hidden or deleted, the next visible EnGuide becomes the active EnGuide. On the other hand, iii and v are false, which means that any visible/invisible EnGuide cannot be selected as an active EnGuide, and if all the electrodes of an active EnGuide are hidden or disconnected, "None" is not selected as the active EnGuide. Therefore, the correct answer is i, ii, iv is TRUE & iii, v is FALSE.

The total number of catheter signals can be calculated by adding up the number of electrodes for each catheter. The first catheter has 1 electrode, the second catheter has 6 electrodes, and the third catheter has 9 electrodes. Therefore, the total number of catheter signals is 1 + 6 + 9 = 16.

The statement is saying that the measured electrode spacing will not be calculated for a field scaled model created with a catheter of undefined electrode spacing. The correct answer is false because the measured electrode spacing can still be calculated even if the catheter used has an undefined electrode spacing.

The statement is saying that only diagnostic catheters with valid electrode spacing can be added to the catalog. Therefore, the correct answer is False, indicating that this statement is not true. This means that diagnostic catheters without valid electrode spacing can also be added to the catalog.

The correct answer is 9. This suggests that there are 9 ports available for a Sensor Enabled catheter added to MediGuide studies.
