Reverse the Numbers.

The psychological burden of cardiac arrhythmia is not theoretical. It is measured, published, and rising. OneRhythm exists to move those numbers in the other direction — through visibility, community, and education.

The Crisis

The Numbers That Started This

Not projections. Not estimates. Taken from real patients. Published in real journals. And still waiting to be fully integrated into routine clinical care.

88.3%

of arrhythmia patients report moderate to severe anxiety

Nature Scientific Reports (2025), N=222

71.1%

report moderate to severe depression

Nature Scientific Reports (2025), N=222

1 in 5

symptomatic AFib patients reported suicidal thoughts

3.9×

increased anxiety risk after ICD shocks

EP Europace (2023), N=39,954

3.2×

mortality risk from elevated PTSD in ICD patients

22.6%

“The psychological consequences of arrhythmia are not quality-of-life footnotes. People are really struggling.”

The Trajectory

The Wrong Direction

Compiled from published prevalence data across multiple decades of cardiology research.

The research is clear. The opportunity to better support patients is growing. OneRhythm’s mission is to help bridge that gap.

Strength in Numbers. Unity in Execution.

Three pillars. One mission. Move the numbers in the other direction.

Visibility

Name it. Measure it. Refuse to look away.

Bring the conversation to the surface. The psychological impact of arrhythmia has been documented in every major cardiology journal on earth. 88.3% anxiety prevalence. 20% suicidal ideation. 3.2× mortality from untreated PTSD. These numbers have names. These names have families. OneRhythm helps make them visible.

Target: Increase public awareness of arrhythmia-related mental health burden

Measure: Media citations, social reach, institutional acknowledgments

Community

You are not alone in this.

Loneliness and social isolation independently predict AF progression and worse cardiac outcomes. The Heart Mosaic is not decoration — it is an evidence-based intervention against isolation. Every ECG contributed is a hand raised in the dark. Every tile placed is proof that the invisible bears don’t get to win.

Target: 25,000 ECG contributions to the Heart Mosaic within 24 months

Measure: Mosaic growth, community engagement, patient-reported isolation reduction

Education

Arm yourself with knowledge.

Routine EHR depression screening catches 2.5% of cardiac patients. Research-grade screening catches 15-40%. That gap represents an opportunity to do better — and patients can help close it. OneRhythm’s educational engine translates peer-reviewed research into questions you can bring to your doctor, information about medical advancements relevant to your condition, and the vocabulary to advocate for your own mental health as a partner in your care.

Target: Every user leaves with at least 3 evidence-based questions for their cardiologist

Measure: Questions generated, educational content engagement, Research Pulse utilization

Institutional Validation

The ESC Is Leading the Way

The 2025 European Society of Cardiology Clinical Consensus Statement on Mental Health and Cardiovascular Disease.

The ACTIVE Framework

Acknowledge

Recognize the multidirectional link between mental health and cardiovascular disease

Check

Screen for mental health symptoms during cardiovascular care

Tools

Use validated screening instruments

Implement

Shared decision-making between patient and care team

Venture

Change the culture of cardiovascular care

Evaluate

Audit current practice against the standard

Every pillar of the ACTIVE framework maps directly to what OneRhythm already does. Acknowledge: the Heart Mosaic makes the burden visible. Check and Tools: the educational engine arms patients with screening vocabulary. Implement and Venture: Research Pulse translates the literature into conversations patients can have with their cardiologists. Evaluate: the platform is open-source and auditable.

The Response

Cardiology has made extraordinary progress in treating arrhythmia. The procedures are better, the devices are smarter, the survival rates are higher. What hasn’t kept pace is the psychological support surrounding that care. Every year the anxiety prevalence data grows clearer, and the opportunity to bridge that gap grows more urgent.

OneRhythm exists to help close that gap - not by replacing clinical care, but by giving patients the tools to see the research, understand it, connect with each other, and walk into their next appointment ready to have a fuller conversation with their care team.

The next number we publish should be the number of people who decided they didn’t have to carry this alone.
