ICD devices

World’s longest lasting implantable defibrillators.1

Home Ürünlerimiz ICD devices


Our ground breaking research has allowed us to develop the world’s longest lasting implantable defibrillator1 which embeds PARAD+TM, a clinically proven arrhythmia discrimination algorithm providing the lowest rate of inappropriate shocks ever reported in the medical literature2, further highlighting our dedication to product innovation.


  • PARAD+™ – World’s first dual-chamber discrimination algorithm. Best-in-class 99% specificity.3
  • SafeR™ – AV Management proven to be safe and effective for all patients with bradyarrhythmia.3,4
  • BTO™ – Unlock Brady and Tachy therapies in the slow VT zone. 96% specificity.5

is the world’s first discrimination algorithm protecting patients from inappropriate shocks for over 20 years.


Brady Tachy Overlap (BTOTM)

allows the patient to benefit from ventricular pacing during exercise while maintaining slow VT detection and therapy.

SafeR Pacing Mode

SafeR is the only AV management algorithm which has been proven to strongly reduce ventricular pacing for AV block patients as well as for SND patients. SafeR reduces the risk of HF hospitalization or cardiac death by 51%. It is designed to intelligently manage AV conduction, diagnosing all types of AV blocks and has been proven to be safe and effective for all brady patients.

Window of Atrial Rate Acceleration Detection (WARAD)

The WARAD is designed to monitor the atrial activity in order to discriminate pathological atrial waves (Atrial Fibrillation, Atrial Flutter, Atrial Tachycardias) from sinus P waves. This atrial discriminator uses atrial prematurity to trigger mode switching.

Fallback Mode Switch (FMS)

The FMS function is designed to diagnose atrial arrhythmias and manage their occurrence using the WARAD (Window of Atrial Rate Acceleration Detection): in the event of atrial arrhythmia, FMS switches from DDD®, SafeR® or Dplus® pacing mode to an inhibited dual- chamber pacing mode DDI® to avoid prolonged ventricular pacing at a high rate for the entire duration of the sustained atrial arrhythmia.

Anti-PMT (Pacemaker Mediated Tachycardia) algorithm

The Anti-PMT algorithm is intended to protect the patient from Pacemaker-Mediated Tachycardia (PMT) without reducing the atrial sensing capability of the device.

Tachyarrhythmia Suspicion and Detection

The primary goal of an Implantable Cardioverter Defibrillator (ICD) is to preserve life by terminating life-threatening ventricular tachycardia (VT) or ventricular fibrillation (VF).

The secondary goal is to deliver therapy only when required and always in the least obtrusive manner.

The third goal is to deliver therapy as painless as possible by giving priority to ATP.

The challenge for any device is to determine whether an elevated ventricular rate corresponds to a true ventricular tachyarrhythmia requiring device therapy or not (in the event that the elevated rate is not of ventricular origin).

PARAD/PARAD+ : P and R Based Arrhythmia Detection

The proper detection of VT requires a specific algorithm (arrhythmia discrimination) to discriminate ventricular tachycardia from Supraventricular tachycardia (SVT) or sinus tachycardia (ST). The MicroPort core algorithms used for rhythms within the VT zone are called PARAD and PARAD+.

ATP in the Fast VT zone

The fast VT zone offers the possibility to attempt painless ATP to terminate fast ventricular arrhythmias in a defined portion of the VF zone.

Automatic Ventricular Sensitivity Control (ASC)

The ASC is an essential of sensing used in MicroPort Implantable Cardiac Defibrillators to ensure appropriate sensing for all ventricular rhythms at all rates. It dynamically adapts the sensitivity to the changing endocardial signal in an attempt to detect each and every R wave.

Brady Tachy Overlap (BTO)

Brady-Tachy Overlap (BTO) is a function which starts as soon as the pacing zone and the Slow VT detection zone overlap by programming the maximum pacing rate faster than the slow VT detection rate. It allows the patient to benefit from biventricular (CRT-D) and ventricular (ICD) pacing during exercise while maintaining slow VT detection and therapy if programmed.

Alerts – System, Lead, Tachy Therapy and Clinical Alerts

In patients’ daily life, some clinical or device-related events need to be communicated to the physician or someone in the hospital or clinic’s team. Alerts are ALWAYS programmed through the programmer. They are triggered automatically by the device when the selected event occurs.
