A "Tech Tip" is a short and easy way to learn technical tip of a NayaMed device feature. This second topic will deal with the subject of Charge Saver.

Saving Battery
Life in
NayaMed ICDs.
ATP during charging provides painless therapy
without delaying the shock if it’s needed.
However, it could cause battery depletion
equivalent to a delivered shock.

3. NAYAMED TECH TIP #2
In NayaMed devices, if ATP during charging with ChargeSaver
are programmed ON, the device switches to ATP Before
Charging if successful ATP during charging therapy has
been delivered.
A study evaluating ATP in the VF zone reported that in 421
implanted patients, 116 VF episodes occurred in 37 patients.
In 4 patients, 38 charges were saved through delivering ATP
Before Charging 1. If you consider that a full-energy charge
reduces longevity by approximately 40 days 2 , that’s a total of
1520 days of longevity that were saved by ATP Before Charging
for those 4 patients (or 380 days/person).
