AI-assisted ICD screening

A fuller picture. More informed ICD decisions.

Deep-ICD turns 24-hour heart recordings into clear, visual insights to help clinicians assess suitability for subcutaneous and extravascular ICDs, revealing changes that state-of-the-art screening practices may miss.

ICD means implantable cardioverter-defibrillator: a device that treats potentially life-threatening heart rhythms.

Why a fuller picture matters

Heart signals change. Screening should capture that.

A short recording captures a moment in time. Deep-ICD is designed to help clinicians explore changes across the day and identify patterns relevant to device suitability and the risk of inappropriate shocks.

See changes over time

Explore the recording across 24 hours, including periods that may warrant closer review.

Make insights easier to review

Bring lengthy recordings into clear visual summaries, with detail available for further examination.

Support personalised assessment

Use the patient's individual recording to inform clinical discussion and screening decisions.

See what Deep-ICD reveals

From a day of recordings to a clearer clinical picture.

Each view leads to the next, from the full recording down to the ECG behind a single prediction.

Deep-ICD's 24-hour overview for a test S-ICD recording: predicted T:R ratios in 10-second windows across the day for vectors A, B and C, with windows above the ratio of concern in red and noisy windows in orange.

01 · Overview

The 24-hour timeline

After submitting a recording for analysis, the clinician sees an overview of the whole day across each recorded vector.

The 24-hour overview with a second timeline beneath it, showing the chosen period from 04:45 to 05:00 in more detail.

02 · Zoom in

A closer look at a chosen time

Choosing a time on the overview opens a second timeline, showing that period in more detail.

A 10-second ECG sample for vectors A, B and C, from 04:55:21 to 04:55:30.

03 · ECG sample

The ECG behind a prediction

Selecting a specific example on the second timeline shows the 10-second ECG sample it came from.

Example output from a test recording: predicted T:R ratios across 24 hours for vectors A, B and C, above histograms of their distribution with the 1:2 ratio of concern marked. Noisy windows: 0.11% for vector A, 0.068% for B and 0.056% for C.

04 · Report

Predicted T:R or P:R ratio distribution

Clinicians can generate a PDF report, including how the predicted T:R or P:R ratios are distributed for each vector.

Example output from a test recording. Deep-ICD is research software, not a tested medical device, and is not for diagnostic use.

The screening approach

Record. Explore. Inform.

  1. 01 · Record

    Capture the 24-hour picture

    A Holter recording captures how the patient's heart signals vary across the day.

  2. 02 · Explore

    Review clear visual insights

    Deep-ICD analyses the recording and presents patterns for closer review.

  3. 03 · Inform

    Support clinical judgement

    Clinicians interpret the findings, using them to inform the shared decision-making process with the patient.
