All the systems have extensive features that allow quick diagnosis and
delivery of safe therapy for cases of bradycardic arrhythmia. The
guided follow-up functions have been largely automated. Initialization
and optimization of Closed Loop Stimulation is also automated. This
saves the physician time and eliminates problems in verifying and
adjusting the pacemaker.
Even during implantation, the implant can detect any connected leads
– one of the key aspects of Auto-initialization.
Cylos features numerous special functions:
• The amplitude control function (which is referred to as ACC, Active
Capture Control) continuously monitors the effectiveness of
ventricular pacing and continuously adjusts the pacing amplitude to
the pacing threshold.
• Closed Loop Stimulation (CLS) is automatically initiated and
optimized.
• Statistics tracking intrinsic AV conduction help optimize the
programmed AV delay and AV hysteresis.
• Antitachycardia functions provide the patient significant protection
from the consequences of tachycardias. Automatic mode conversion
or automatic mode switching prevent atrial-controlled pacing in the
case of atrial tachycardias.
• A preventive overdrive mode reduces the occurrence of atrial
tachycardias by using minimal overdrive pacing of the patient’s
intrinsic rate.
• Extensive algorithms help to prevent, recognize, and terminate
tachycardia induced by the pacemaker.
