Rhythm devices demand evidence that lasts years.
Pacemakers, ICDs, CRT, ablation catheters and EP mapping sit at the top of the risk scale. We run the Class III and active implantable investigations, the long-term PMCF and the registry evidence that a Notified Body expects for cardiac rhythm management devices.

Device leaders rely on Eclevar for cardiology and rhythm management evidence. Read all client success stories.

Rhythm evidence a reviewer will accept.
Dr Mark DaCosta, COO and former TÜV SÜD reviewer, leads a team that knows how a Notified Body scrutinises active implantable and Class III cardiac devices. We design lead-survivorship endpoints, long-term follow-up and PMCF so the benefit-risk case holds, with in-house CRAs rather than outsourced monitoring.
The full arrhythmia device landscape.
From high-energy implants to diagnostic monitors, we cover the cardiac rhythm management portfolio, connecting each to our wider cardiovascular clinical strategy.
Pacemakers & CRT
Single, dual-chamber and biventricular resynchronisation devices, including leadless systems.
ICDs
Implantable cardioverter defibrillators, transvenous and subcutaneous, with shock-therapy endpoints.
Ablation catheters
Radiofrequency, cryo and pulsed-field ablation for atrial fibrillation and other arrhythmias.
EP mapping systems
Electrophysiology mapping and navigation platforms, hardware and software.
Loop recorders
Implantable and external monitors for long-term arrhythmia detection.
Leads & accessories
Lead survivorship and extraction data, central to the long-term benefit-risk profile.
Endpoints built for rhythm devices.
We combine device performance and long-term safety, captured through clinical investigations and registry-based real-world evidence.
Does the device do its job
- Sensing, pacing and shock-therapy performance

Rhythm device questions sponsors ask us.
Which cardiac arrhythmia devices does Eclevar support?
Pacemakers, implantable cardioverter defibrillators (ICDs), cardiac resynchronisation therapy (CRT) devices, ablation catheters, electrophysiology mapping systems and implantable loop recorders, including Class III and active implantable (AIMD) devices.
How are arrhythmia devices classified under EU MDR?
Most cardiac rhythm management implants are Class III or active implantable devices under EU MDR 2017/745, which triggers the highest clinical evidence expectations, mandatory PMCF and, for implantables, an SSCP.
What clinical endpoints matter for rhythm management trials?
Endpoints typically combine device performance (sensing, pacing and shock therapy), procedural safety, arrhythmia recurrence, lead performance and long-term survival, captured over multi-year follow-up.
Can registries support PMCF for arrhythmia devices?
Yes. Registry-based PMCF and real-world evidence are well suited to rhythm management devices, where long-term lead and device survivorship are central to the benefit-risk profile.
Does Eclevar run the sites itself?
Yes. Eclevar deploys in-house CRAs across the UK, Germany, France and Sweden, handling site initiation, ethics submissions and monitoring with its own team rather than outsourcing.
