What / is are the condition(s) to be true for EnGuide Stability Monitor to detect shifts of catheter locations.

At least one catheter should be defined with valid magnetic data.
Positional Reference Sensor should be enabled with valid magnetic data.
Metal Distortion Sensor should be disabled.
A magnetic field scaled model should be present in the study.
At least one map should be created.
The respiration Gating Algorithm should be enabled even if the respiration data is not collected.
All the catheters (if multiple catheters defined) should have valid impedance data

Correct Answer(s)

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.

An Autosegment called Placed first 3D Point is saved when

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.

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.

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.

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.

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.

During a clinical study with both Impedance & Magnetic System is used for navigation of the catheters, when does the magnetic sensor present in the catheter doesn't transfer the Magnetic Location information to the software. i. If Positional Reference Sensor is broken. ii. If Metal Distortion Sensor is broken. iii. When Catheter is connected to an invalid magnetic port.

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.
