3-2-1 Arrhythmia

Arrhythmia is when the heart beats with an irregular rhythm, too fast, too slow, or unpredictably due to disruptions in the heart’s electrical signals. While some arrhythmias are harmless, others can lead to serious complications like stroke or cardiac arrest if left untreated. Symptoms may include palpitations, dizziness, shortness of breath, chest discomfort, or even fainting, though some people experience no symptoms. The most common type is atrial fibrillation (AF), which causes a fast and irregular heartbeat. Arrhythmias can result from heart disease, high blood pressure, certain medications, or lifestyle factors such as caffeine or alcohol use. Diagnosis typically involves an electrocardiogram (EKG) and sometimes longer-term heart monitoring. Treatment depends on the type and severity, ranging from lifestyle changes and medications to procedures or devices that help regulate heart rhythm
Globally, arrhythmias impact a substantial portion of the population. Recent estimates indicate that 1 in 3 people worldwide will develop a potentially life-threatening arrhythmia during their lifetime. The most common type, atrial fibrillation (AF), has seen a sharp rise in prevalence, with projections suggesting this number could increase by more than 60% by 2050. Overall, arrhythmias are recognized as a growing and major health concern worldwide.
3 startups making an impact in this space:
Company | |||
Location | Europe | US | US |
Modality | Diagnosis | Diagnosis | Treatment |
Descriptor | Remote atrial fibrillation (AF) detection and monitoring. | Eko can detect the most subtle signs of heart and lung disease by digitizing the stethoscope. | Revolutionizing cardiology by bringing the most advanced ablation tools to market. |
Core Problem | It is hard to detect AF in patients since patients may not display any symptoms. Also, patients need extensive hardware and monitoring to diagnose arrhythmias. | Over 60% of heart diseases go undiagnosed. Missing the warning signs of disease can lead to serious complications and outcomes. | Current cardiac ablation treatments are not efficient and may have unintended consequences. |
Solution | FibriCheck is a medically certified and FDA-cleared tool to detect and monitor arrhythmias. Patients can use their smartphones, negating any need for special hardware. | FDA-cleared solution enables early detection using AI-powered enhanced audio and real-time visualizations. | Pulsed Field Ablation (PFA) catheters aim to improve existing ablation technology by using microbursts of energy to disrupt heart cells within fractions of a second and minimize unintended impacts on surrounding areas. |
Product Suite | FibriCheck patient-facing app. Validated AI algorithm for detection. Portal for healthcare providers. | 3M Littman Digital Stethoscope - cardiology grade. Eko Core Stethoscope - 3-lead ECG with AI insights and Afib/ Murmur detection Eko Digital attachment - Transforms an analog stethoscope to digital. | Next-generation pulsed field ablation (PFA) solution for treatment of cardiac arrhythmia. |
Regulatory Status | FDA-cleared | FDA-cleared | Breakthrough device for ventricular tachycardia. |
Funding Stage | Series A | Series D | Series A |
Team | The founder’s father suffered a stroke, and that led him to work in this space. | Co-founder’s thesis at Berkeley made him realize the limitations of traditional stethoscopes. | The CEO is a board-certified clinical cardiac electrophysiologist. |
Traction | Significant traction, including NHS and J&J. | Significant traction, including several key health systems. | Early stage |
2 actionable insights to inspire your strategy.
Remote Monitoring & Virtual Care There is a continued shift toward remote cardiac monitoring, using wearable ECG devices and patches to detect arrhythmias outside the clinic. This trend is complemented by virtual consultations and telehealth, which improve access to arrhythmia care, especially for chronic disease management and follow-up. More arrhythmia procedures and diagnostics are moving from hospitals to ambulatory surgery centers and outpatient settings, making care more accessible and cost-effective. | AI/ML Advances in machine learning have significantly improved the sensitivity and specificity of computerized ECG interpretation, with some AI models now outperforming average cardiologists in arrhythmia detection. AI-driven tools are increasingly used for arrhythmia detection, risk prediction, and real-time decision support during procedures. AI algorithms are also being applied to imaging (e.g., echocardiograms) to detect subtle or hidden arrhythmias that may not be evident during routine exams. |
