5. Blazer II™ Ablation Catheter AVNRT
AV NODE
Regulates the conduction between the Atrium and Ventricle
Composed of a fast and slow pathway
In a healthy heart, the fast and slow pathway cancel each other depending on the bpm
AVNRT
Atrial Ventricular Nodal Re-entry Tachycardia
PAC initiates a re-entry circuit in the AV Node
Reentrant circuit around 50 msec
Stimulates both the A and V
NSR – conduction through the AV node via the fast pathway

6. Blazer II™ Ablation Catheter AVNRT
Sinus Rhythm – slow pathway and fast pathway can not both be activated
AVNRT – a PAC comes in at a different time and is able to conduct through the slow pathway, up the fast pathway and start a reentry circuit

7. Blazer II™ Ablation Catheter AVNRT
Mapping and Ablating AVNRT
Mapping usually done with three fixed DX catheters (RA, His and RV)
Confirm AH jump between slow and fast conduction
Ablation of the slow pathway
posterior and anterior to the AV node
Post ablation confirm no AH jump

8. Blazer II™ Ablation Catheter AVNRT
Summary
Symptoms
Lightheadedness
Rapid palpitations
Pulsations in the neck
Regular rhythm with narrow QRS
No visible P wave (may be buried at end of QRS)
A and V stimulate simultaneously (reentry <50msecs)
Ventricular rates between 160 – 200 bpm
Paroxsysmal
Starts and stops suddenly
Most common SVT
Treated by ablating the slow pathway of the AV Node

14. Blazer II™ Ablation Catheter Evaluation Model
When preparing the evaluation of new customer please follow the SIX easy steps outlined below:
STEP 1:
Schedule minimum 2 AVNRT cases during the same day for the evaluation.
STEP 2:
The evaluation should be performed with Maestro 3000™ generator.

15. Blazer II™ Ablation Catheter Evaluation Model
STEP 3:
Discuss with the Physician whether he/she wishes to use Standard or Large curve

16. Blazer II™ Ablation Catheter Evaluation Model
STEP 4:
Suggest to the Physician to use high torque distal segment (HTD) because of its high performance. However, you may wish to mention to certain physicians that a standard torque distal segment, which minimizes vascular and endocardial trauma, is also available.

STEP 6: Before doing the ablation make the test on Maestro 3000™ - as described in the following slide.
The test must be done in order to verify the compatibility of the generator with the recording system installed in the cat lab.
Tester required.
