Study summary

This registry is performed for the long-term assessment of outcome, performance and residual safety aspects of the BIOMONITOR III and possible successors in a real-life clinical set-up. In addition, this registry is set up in a way that it may also be used as a platform for submodules to investigate additional scientific and regulatory aspects while minimizing the additional effort for the investigational sites and patients.

Study population

The intended patient population consists of all patients who would benefit from long-term cardiac rhythm monitoring.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patient is intended to receive a BIOTRONIK Implantable Cardiac Monitor (ICM)
  • Patient is able to understand the nature of the registry and to provide written .
  • Patient is willing and able to use the CardioMessenger and accepts the BIOTRONIK Home Monitoring concept.

  • Patient is less than 18 years old.
  • Patient is participating in another interventional clinical investigation other than the submodules of BIO\|STREAM.ICM
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Time to diagnosis

    Device is intended to detect rare arrhythmias. Time to detect this relevant arrhythmia will be recorded.

    Time frame: The time to a relevant diagnosis can vary significantly. The time period starts with the insertion of the device.

Secondary outcomes

  1. Insertion procedure and success

    Information on the insertion procedure (Operation time, handling of the BIOMONITOR incl. incision and insertion tool); Success rate of insertions.

    Time frame: Data on BIOMONITOR insertion procedure and success rate are collected at day of insertion.

Other outcomes

  1. Sensing and noise

    Quality of sensing Amplitude (Millivolt) and electrical noise (%) detected by the BIOMONITOR.

    Time frame: Data will be collected throughout the entire registry, i.e. until February 2023 (Last patient out).

  2. Inspection results of the insertion site

    Rating of wound healing and cosmetic outcome by the physician/patient (5-level scale).

    Time frame: Data will be collected throughout the entire registry, i.e. until February 2023 (Last patient out).

  3. Patient contentment regarding BIOMONITOR wearability

    Patients opinion about the wearing comfort (5-level-scale).

    Time frame: Data will be collected throughout the entire registry, i.e. until February 2023 (Last patient out).

  4. Device migration

    Assessement whether the BIOMONITOR migrates under the skin.

    Time frame: Data will be collected throughout the entire registry, i.e. until February 2023 (Last patient out).

  5. Diagnosis and clinical actions after arrhythmia detection

    Documentation whether the BIOMONITOR helps to detect arrhythmias. Documentation of therapies used to treat these arrhythmias and whether the BIOMONITOR helps to monitor therapy success.

    Time frame: Data will be collected throughout the entire registry, i.e. until February 2023 (Last patient out).

  6. Explantation / deactivation / exchange information of the BIOMONITOR

    Collect information about explantation, deactivation and exchanges of the BIOMONITOR, such as number, reason, and data on procedure.

    Time frame: Data will be collected throughout the entire registry, i.e. until February 2023 (Last patient out).

  7. Adverse Events

    Collect and analyze adverse events.

    Time frame: Data will be collected throughout the entire registry, i.e. until February 2023 (Last patient out).

  8. Device Deficiencies

    Collect and analyze device deficiencies. Calculate rate (frequency) of device deficiencies.

    Time frame: Data will be collected throughout the entire registry, i.e. until February 2023 (Last patient out).

  9. Documentation of imaging techniques, if applied.

    Documentation if patients underwent any MRI examinations or mammography. Documentation of exact kind of examination and occurrences with regard to the BIOMONITOR.

    Time frame: Data will be collected throughout the entire registry, i.e. until February 2023 (Last patient out).

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2019 (actual). Primary completion is estimated for May 2027, 91 months after the start.

Of 27 observational studies under Tachycardia, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 43. This study's planned 91 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 1, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
