Therapeutic and Diagnostic Functions
Diagnostic functions
Data from implantation and the most recent interrogations and follow-ups are
recorded as well as arrhythmia episodes; they are stored together with other data
to assess patients and the state of the device at any time.
To check the lead for proper functioning, an automatic impedance measurement
using subthreshold pacing pulses is performed in the device.
Leadless ECG function: For all device types, far-field derivation can be measured
without external leads between the right ventricular shock coil and housing, which,
depending on the implantation site, corresponds to ECG derivation II or III
(Einthoven).
Once a telemetry connection has been established during a test procedure in an in-
office follow-up, the leadless ECG and the IEGM are displayed with markers.
Antitachycardia pacing
The ICD can treat ventricular tachycardia with antitachycardia pacing (ATP); ATP can
also be delivered in the VF zone (ATP One Shot) when the stability criterion indicating
that this will be effective before shock delivery (monomorphic rapid VTs) is met.
Arial tachycardia can be treated with antitachycardia pacing (atrial ATP) at stable
heart rhythms and with high frequency bursts (HF burst) at instabil heart rhythms.
Depending on the device type, the device program contains not only the ICD func-
tions but also all pacemaker functions for 1, 2, or 3 chambers. The heart rhythm is
continuously monitored; each arrhythmia is classified according to the heart rate
and the adjustable detection criteria. Depending on the preset values, antibrady-
cardia as well as antitachycardia therapy is inhibited or delivered.
Cardioversion, defibrillation
The ICD can treat ventricular tachyarrhythmia with cardioversion and/or defibrilla-
tion. Shock polarity and energy can be programmed individually. Shock energies
between 2.0 and 45 J are possible. Before delivery of the shock, the ICD can be set
to only deliver a shock when ongoing tachyarrhythmia is confirmed; during this
time period the device can identify spontaneous conversion of the tachyarrhythmia
and cancel the charging process if necessary.
The shock paths can be set between the different shock coils (SVC/RV) and/or the
housing.
