HIPAA Compliance for Cardiology Practices: ECG Data and Remote Monitoring
Cardiology’s defining HIPAA challenge is that a large share of its data is now generated outside the clinic, streaming continuously from devices implanted in or worn by patients at home. Pacemakers, implantable cardioverter-defibrillators (ICDs), implantable loop recorders, Holter and event monitors, and remote blood-pressure and weight sensors transmit electronic PHI around the clock through device manufacturers and monitoring vendors before it ever reaches the cardiologist. Add high-volume ECG and echocardiogram imaging, and cardiology becomes a specialty where ePHI is constantly in motion across third parties. Securing that flow of remote cardiac data is what sets cardiology compliance apart.
Remote monitoring and the business-associate web
When a patient’s ICD transmits an arrhythmia alert from a bedside monitor, that data typically travels through the device manufacturer’s network and a remote-monitoring service before landing in your system. Each company that receives, stores, or transmits identifiable cardiac data on your behalf is a business associate, and you need a Business Associate Agreement with each one. Cardiology practices often have more remote-monitoring and device relationships than they realize, and an un-papered vendor handling cardiac telemetry is a direct compliance gap. Remote patient monitoring programs add home blood-pressure cuffs and scales that feed the same obligations.
ECG, echo, and imaging data
ECG tracings, echocardiograms, stress-test results, and cardiac catheterization images are all PHI, frequently stored in a cardiovascular information system or PACS separate from the main EHR. Those systems need their own access controls, encryption, and audit logging, and any cloud storage or analysis vendor handling them is a business associate. Because cardiac images and waveforms are often shared with referring physicians and hospitals, encrypted transfer is essential rather than optional.
The Security Risk Analysis
HIPAA’s Security Rule requires a Security Risk Analysis under 45 CFR § 164.308(a)(1)(ii)(A) — an accurate, thorough assessment of risks to all electronic PHI. For cardiology, the SRA must reach beyond the EHR to include device-monitoring platforms, the cardiovascular information system, remote patient monitoring tools, and every vendor that carries cardiac data. Because so much cardiology ePHI originates outside your walls, the SRA is the only way to get a complete map of where it travels and where it’s exposed. A HIPAA compliance checklist helps confirm none of those connections are missed.
The proposed 2026 Security Rule update
In December 2024, HHS published a Notice of Proposed Rulemaking to strengthen the HIPAA Security Rule, with proposed requirements including mandatory encryption, multi-factor authentication, network segmentation, and more frequent risk analyses. The proposal is not final and remains in the rulemaking process; if finalized as written, covered entities would have roughly 240 days from the effective date to comply. For cardiology’s many remote-monitoring connections, tighter encryption and authentication standards would touch a wide web of vendors, so it is wise to strengthen those controls ahead of any deadline.
How Medcurity helps
Medcurity helps cardiology practices run a guided Security Risk Analysis that maps their full remote-monitoring and imaging footprint, inventory the device manufacturers and monitoring vendors that handle cardiac ePHI, track Business Associate Agreements, and keep documentation ready for an audit. The platform is $499/year (about $42/month) for a single practice, with quotes available for larger cardiology groups and multi-site organizations. It brings the scattered, always-on world of cardiac data into one defensible compliance view.
Frequently asked questions
Is data from pacemakers and other cardiac monitors considered PHI?
Yes. Telemetry from pacemakers, ICDs, loop recorders, and remote monitors is identifiable health information about a patient, so it is electronic PHI and must be protected throughout its journey from the device to your practice.
Are cardiac device manufacturers and remote-monitoring vendors business associates?
When they receive, store, or transmit your patients’ identifiable cardiac data on your behalf, yes. Each is a business associate requiring a Business Associate Agreement, and cardiology practices frequently need agreements with several device and monitoring companies.
Does ECG and echocardiogram data need the same protection as EHR records?
Yes. Cardiac waveforms and images are PHI even when stored in a separate cardiovascular information system or PACS. Those systems require their own encryption, access controls, and audit logging, and any vendor handling them needs a Business Associate Agreement.
How does the Security Risk Analysis apply to remote cardiac monitoring?
Your SRA must include every device-monitoring platform and vendor that carries cardiac ePHI, not just the EHR, documenting the risks and safeguards for each under 45 CFR § 164.308(a)(1)(ii)(A). Because cardiology data originates largely outside the clinic, this mapping is essential.
