People also ask
How does the ATAC procedure work?
The ATAC procedure begins at the back of the vehicle and traces a streamline forward to the stagnation point. This assures a reasonable distribution at the end of the vehicle and eliminates the effects of the ablated nosetip on the streamlines.

What is cardiac ablation?
Dr. Anet Varghese
Doctor of Medicine (MBBS) · 1 years of exp
Cardiac ablation uses heat or cold energy to create tiny scars in the heart to block irregular electrical signals and restore a typical heartbeat. The procedure is used to correct heart rhythm problems. It is most often done using thin, flexible tubes called catheters inserted through the veins or arteries. Less commonly, ablation is performed during cardiac surgery.

What does a successful ablation mean for a patient?
If an ablation is successful, the patient is cured. Recovery after ablation for some patients is straightforward. Their quality of life improves, and they may no longer have palpitations or episodes of SVT.

How does the ATAC solution work?
The ATAC solution integrates both pressure and wall shear to determine the drag on the vehicle. Also included in Figure 23 are CFD predictions by Mike Wright of ELORET. The ATAC predictions are in good agreement with these CFD values.

What does catheter ablation treat?
Catheter ablation treats fast heartbeats. This minimally invasive procedure stops the electrical impulses that cause irregular heart rhythms. Heart arrhythmias (irregular heartbeats) that can’t be controlled with medication may benefit from catheter ablation.

How does a vascular ablation procedure work?
The ablation procedure proceeds in steps. After vascular access is obtained, the arrhythmia is induced to confirm the diagnosis and to establish whether abolishing inducible VT is a potential end point for the procedure. Mapping is performed to locate the source, followed by ablation. Testing is then performed to assess the effect of ablation.
