    A. At least one catheter should be defined with valid magnetic data.
    A. Positional Reference Sensor should be enabled with valid magnetic data.
    A. A magnetic field scaled model should be present in the study.
    Explanation
    To detect shifts of catheter locations, the EnGuide Stability Monitor requires several conditions to be true. Firstly, there should be at least one catheter defined with valid magnetic data. Additionally, the Positional Reference Sensor should be enabled with valid magnetic data. Furthermore, a magnetic field scaled model should be present in the study. These conditions ensure that the monitor has the necessary information and tools to accurately detect shifts in catheter locations.

    Identify the control(s) which are recorded historically in a segment. 

    • Active EnGuide

    • Stabilize ABL

    • Apply/Update Respiration Compensation

    • Show Mapping Metrics

    • Reference and Roving Sources

    • The polarity of a catheter

    Correct Answer(s)
    A. Active EnGuide
    A. Stabilize ABL
    A. Apply/Update Respiration Compensation
    A. The polarity of a catheter
    Explanation
    The control(s) that are recorded historically in a segment are Active EnGuide, Stabilize ABL, Apply/Update Respiration Compensation, and the polarity of a catheter. These controls are likely recorded over a period of time to track and analyze the performance and effectiveness of the segment. The other options, Show Mapping Metrics and Reference and Roving Sources, do not seem to be controls that would be recorded historically.

    • The first map is created after validating the study.

    • When an empty model without surface points is created after validating the study

    • If a Surface Lesion is placed after validating the study

    • A map point is saved on a catheter after validating the study.

    • A Label is placed on a catheter.

    Correct Answer(s)
    A. The first map is created after validating the study.
    A. A map point is saved on a catheter after validating the study.
    A. A Label is placed on a catheter.
    Explanation
    The correct answer is "The first map is created after validating the study," "A map point is saved on a catheter after validating the study," and "A Label is placed on a catheter." These actions all occur after validating the study and are associated with saving an Autosegment called *Placed first 3D Point*.

    Field Scaling is not computed successfully in a Magnetic study without valid Magnetic data and enough Magnetic fiducials unless and until NavX Only Field Scaling is enabled.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The explanation for the given correct answer is that in a Magnetic study, the Field Scaling cannot be computed successfully without valid Magnetic data and enough Magnetic fiducials unless the NavX Only Field Scaling is enabled. This means that without the necessary data and fiducials, the scaling of the magnetic field cannot be accurately determined. Therefore, the statement is true.

    Loading a Bookmark pauses the playing segment at a specific timestamp at which the Bookmark is saved.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    When loading a bookmark, the playback of a segment is paused at a particular timestamp where the bookmark was saved. This means that when a user accesses a bookmark, they can resume playback from the exact point where they left off, making it a convenient feature for quickly navigating through long audio or video files. Therefore, the statement is true.

    Rate this question:

  • 7. 

    How many Sensor Enabled catheters can be used in a NavX SE Study with valid magnetic data.

    • 4

    • 9

    • 6

    • 0

    Correct Answer
    A. 4
  • 8. 

    If the catheters are moving rapidly in 3D Display due to patients irregular breathing pattern which feature helps to reduce the rapid catheter movements

    • Apply Respiration Compensation

    • Apply Respiration Rejection

    • Update Respiration Compensation

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the above options help to reduce the rapid catheter movements caused by the patient's irregular breathing pattern in a 3D display. Applying respiration compensation adjusts the catheter's position based on the patient's breathing pattern to minimize movement. Applying respiration rejection filters out the effects of the patient's breathing, allowing for a clearer display of the catheter's position. Updating respiration compensation ensures that any changes in the patient's breathing pattern are accounted for and the catheter's position is adjusted accordingly. Therefore, all of these features contribute to reducing rapid catheter movements in a 3D display.

    Bookmarks can be saved while playing a segment in Realtime Review. 

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Bookmarks cannot be saved while playing a segment in Realtime Review.

    Rate this question:

  • 10. 

    A catheter connected to an Ablation Channel (Genconnect) can also be used as a Positional Reference Electrode.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because a catheter connected to an Ablation Channel (Genconnect) cannot be used as a Positional Reference Electrode. Ablation catheters are specifically designed for delivering energy to ablate or destroy tissue, while a Positional Reference Electrode is used to measure the electrical activity of the heart during a procedure. These are two different functions and cannot be performed by the same catheter.

  • 11. 

    During a clinical magnetic study, when the patient having Positional Reference and Metal Distortion Sensor with valid magnetic data placed on his/her body has moved outside the magnetic field, the quality indicators in the software are displayed in ________ color.

    • Green

    • Grey

    • Amber

    • None of the above

    Correct Answer
    A. Amber
    Explanation
    When the patient with the Positional Reference and Metal Distortion Sensor moves outside the magnetic field during a clinical magnetic study, the quality indicators in the software are displayed in amber color. This color is likely used to indicate a warning or cautionary state, suggesting that the magnetic data may be compromised or inaccurate due to the patient's movement.

    Identify the condition(s) which trigger an Automatic Segment Record.

    • When Automap is done without an automatic record, AutoMap is enabled.

    • When Automarks are collected without an automatic record of RF Session is enabled.

    • Sheath Detection is Initialized on a Sensor Enabled catheter.

    • All of the above. 

    Correct Answer
    A. Sheath Detection is Initialized on a Sensor Enabled catheter.
    Explanation
    The condition that triggers an Automatic Segment Record is when Sheath Detection is Initialized on a Sensor Enabled catheter.

    Rate this question:

  • 13. 

    How many segments named AutoSegment will be created if the application is run for 90 minutes after validation?

    • 6

    • 9

    • 3

    • 1

    Correct Answer
    A. 6
    Explanation
    If the application is run for 90 minutes after validation, it can be inferred that the AutoSegment will be created at certain intervals of time. Since the question does not provide any specific information about the frequency of creating AutoSegments, it can be assumed that a new segment named AutoSegment will be created every 15 minutes (90 minutes divided by 15). Therefore, if the application is run for 90 minutes, a total of 6 segments named AutoSegment will be created.

    • Ii is Correct

    • I & iii is Correct

    • Ii & iii is Correct

    • All of the above is Correct

    Correct Answer
    A. I & iii is Correct
    Explanation
    The correct answer is i & iii is Correct. This means that the magnetic sensor in the catheter will not transfer the Magnetic Location information to the software if the Positional Reference Sensor is broken or if the catheter is connected to an invalid magnetic port.
