A "Tech Tip" is a short and easy way to learn technical tip of a NayaMed device feature. This third topic is covering a best practice in programming Wavelet.

Wavelet
The Wavelet feature compares the patient’s current QRS
waveform to a collected and stored template of the
patient’s QRS waveform in sinus rhythm. VT/VF detection
is withheld if the current waveform sufficiently matches
the template thereby preventing inappropriate therapy for
sinus tachycardia or SVT.

NayaMed ND X4 VR Clinical Manual, Page 191.
The NayaMed single-chamber ICDs use the EGM2 channel for
template creation and comparison. Nominally the EGM2 source
is set as Can to RVcoil and the EGM2 Range is ±12 mV.
Wavelet may be tailored to your patient by simply printing
EGM2 (using the programmer strip chart recorder) and
evaluating the signal:
If the baseline-to-peak R-wave amplitudes are too large (either clipped
or within 1 mV of the EGM2 Range), consider selecting a larger EGM2
Range value.
If the peak-to-peak R-wave amplitudes on the EGM2
trace are less than 3 mV, consider selecting a different
EGM2 source.
