Key Findings
Our research demonstrates that adversarial beats can successfully spoof arrhythmia in automated ECG diagnosis systems, with a significant real-world success rate. This poses a direct threat to the integrity of medical diagnoses and could be leveraged for fraudulent activities.
42.1%
Attack Success Rate in Real-World Scenarios (for spoofing 7 V heartbeats/minute)
Enterprise Implications
For healthcare providers and medical device manufacturers, this research highlights an urgent need for enhanced cybersecurity measures. The potential for misdiagnosis, fraudulent insurance claims, and compromised patient care necessitates immediate action. Implementing robust defense strategies, including advanced signal processing, ensemble classification, and enhanced human oversight, is crucial to mitigate these sophisticated attacks. Neglecting these vulnerabilities could lead to severe financial penalties, erosion of trust, and adverse patient outcomes.

Chance of spoofing 7 V heartbeats/minute (leading to cardiomyopathy misdiagnosis)
Real-World Impact: Medical Fraud & Misdiagnosis
Adversarial beats can be leveraged by malicious patients to spoof the presence of serious heart conditions like Premature Ventricular Contraction (PVC), leading to a faked diagnosis of PVC-induced cardiomyopathy. With an average attack success rate of 42.1% for spoofing 7 V heartbeats per minute, attackers can repeatedly attempt to establish a fraudulent medical insurance claim. This could result in unnecessary medication prescriptions (e.g., β-blockers) and significant financial incentives for fraud, highlighting a critical vulnerability in automated ECG diagnosis systems.

Diagnostic Report
| Feature | Hardware-Based (Our Approach) | Software-Based (Existing) |
|---|---|---|
| Attack Domain | Analog signals into ECG hardware, real-world constraints (frequency response, impedance matching) | Mathematical perturbations to digitized signals (sample-wise independence, clinically implausible artifacts) |
| Constraint Adherence | Physical constraints (e.g., amplitude, frequency band, temporal shifts) explicitly considered | Unconstrained digital perturbations, often clinically implausible |
| Success Metrics | Real-world implementability, 42.1% success rate reflecting physical constraints | Numerical >90% success rates without physical constraints, methodological superiority not applicable to hardware |
| Threat Model | Physical hardware access, analog acquisition level bypassing digital security | Digital access to systems |
| Implementation | End-to-end implementation with commercial hardware | Theoretical vulnerabilities demonstrated |
| Novelty | Novel attack vector complementing existing software research | Focus on software-based vulnerabilities |

Proposed Mitigation Strategies
To counter the threat of adversarial beats, a multi-faceted defense approach is required. This includes Advanced Signal Processing for detecting adversarial patterns, Physical Constraint Verification to ensure physiological plausibility, Ensemble Classification with diverse models, and Anomaly Detection Systems for unusual patterns. Crucially, Enhanced Human Oversight by trained cardiologists and Multi-Modal Verification (cross-validation with other physiological measurements) are essential operational defenses. Finally, Secure Hardware Design with tamper-evident features and signal authentication provides foundational protection.
