Technical Data
Resistance to interference • Note on device type DX (only devices with a DF-1/IS-1 connection): The EMC
requirements are met as long as atrial sensitivity is set to 1.0 mV (factory set-
tings) or values ≥ 1.0 mV. Measures must be taken to assure interference-free
therapy if more sensitive values are set.
• Note on device type HF: In the case of unipolar sensing, the requirement for
interference voltages of ≤ 0.3 mV (tip to tip) is met.
Common mode rejection
ATP amplitude A burst was measured at 500 Ω, an amplitude of 7.5 V (tolerance ±1.5 V), pulse
width of 1.5 ms, R-S1 interval of 300 ms and an S1 count of 5:
Automatic sensitivity
setting
Measurement of actual values and test signal wave shape: standard triangle. For
the device type DX, the programmed atrial sensitivity is intensified by a factor of 4.
