Cardiology practices that implant devices from more than one manufacturer face an immediate problem. Staff must maintain separate logins, learn separate interfaces, and manually reconcile data from systems that don't talk to each other. Each manufacturer uses its own nomenclature, technical standards, and communication protocols for similar features, which turns consolidation into a manual, error-prone task that eats hours of clinical staff time daily.
Traditional EHR systems aren't built to manage CIED data, and standalone tools have had only mixed success extracting data from proprietary formats. When workflows depend on PDFs, scanned reports, or disconnected portals, extracting useful information becomes slower and more resource-intensive, cutting into the value of remote monitoring programs.
Transmission volume is climbing fast. Device clinics process thousands of transmissions annually, and many of those alerts carry no clinical significance. Some clinics have seen their device populations grow substantially since 2018 and now manage thousands of devices. That growth creates a real bottleneck risk, as Marcus Pritchett, Cardiac Device Specialist at Kansas City Heart Rhythm Institute, described: "You can imagine with all of that information flowing in, if we don't accommodate for all of the increase and influx of information, we're going to have a bottleneck… the last thing we want is to expose patients to bad patient care and expose our doctors and our APPs to maybe missing something that's very clinically relevant that could compromise patient care."
The financial fallout follows a clear chain. Billing depends on clean data segmentation, but most clinics lack the infrastructure to support it, which pushes staff toward manual data entry. That manual step is prone to transcription errors, and those errors compound downstream. When data mapping is incomplete, EHR workflows frequently produce delayed claims submission or failed documentation.
Andrew Beaser, MD, Associate Professor of Medicine at the University of Chicago Medicine (UCM), described pre-implementation workflows as "a major challenge and incredibly difficult." Gaurav A. Upadhyay, MD, FACC, FHRS, Professor of Medicine and Director of the Pacing & Defibrillation Device Clinic at UCM, added: "Staffing was always an issue for our center, because our device clinic — like many other medical centers — had struggled with technician turnover and timely weekend coverage."
Vendor-neutral arrhythmia monitoring platforms fix fragmentation by acting as a single data layer above all OEM systems. Instead of forcing staff into manufacturer-specific portals, these platforms ingest data through APIs, HL7 feeds, XML, and PDF parsing. They normalize that data into one format and present it through a unified clinical interface.
The core capabilities that define this category include:
Anjali B. Thakkar, MD, member of the American College of Cardiology's Health Care Innovation Council, put it this way: "I envision a future in which data analytics are used to consolidate large amounts of remote-monitoring data and present clear and accurate management recommendations on the guideline-directed next steps." Practices running a unified platform are already living in that future.
Rhythm360 by RhythmScience is a cloud-based, HIPAA-compliant platform that pulls CIED data from Medtronic, Boston Scientific, Abbott, Biotronik, and other manufacturers into a single source of truth. It reaches a data transmissibility rate above 99.9% through redundant data feeds, computer vision (OCR), and AI-powered extrapolation. Critical information doesn't get lost to OEM server outages or format mismatches.
The platform's alerting system filters non-actionable transmissions and prioritizes clinically significant events such as new-onset atrial fibrillation, ventricular tachycardia, lead malfunction, and ERI/RRT indicators. Optional 24/7/365 oversight by certified cardiac technicians (CCTs), supervised by physicians, adds a human review layer. Together, these features cut critical alert response times by up to 80%.
Rhythm360 also runs distinct but connected service lines for Rhythm-CIED (implantable devices) and remote physiological monitoring for heart failure and hypertension. This matters because roughly 30% of patients who qualify for CRT don't respond favorably to the therapy, so close monitoring of both device data and comorbid conditions is critical. Without a unified workflow, data streams from CRT devices get split between separate EP and HF teams, creating confusion, redundant work, and gaps where critical information slips through.
The secure, HIPAA-compliant mobile app lets electrophysiologists and clinical staff review transmissions, sign reports, and coordinate care from anywhere. A Twilio-powered communication hub tracks all patient messaging and call logs with a full audit trail, cutting out redundant outreach and documenting every interaction in the patient record.
UCM's implementation of Rhythm360 let clinicians review more transmissions daily and catch more abnormalities, with Dr. Beaser noting: "We are able to address these issues earlier; rather than waiting for a 3-month visit, we can call patients in for evaluation."
Remote arrhythmia monitoring generates billable events across a complex set of CPT codes. Each requires precise documentation of transmission days, device types, and staff time. Without automated tracking, practices routinely miss eligible claims or submit incomplete documentation that gets denied.
The 2026 CMS Physician Fee Schedule introduced expanded RPM codes 99445 and 99470, allowing billing for shorter 2 to 15 day data collection periods within a 30-day window. The relevant codes for cardiology practices include:
Rhythm360 automates CPT code capture and generates compliant documentation for each code, tracking transmission days, staff time, and patient consent inside the platform. Practices using Rhythm360 have seen revenue increases of up to 300% through better CPT code capture, improved staff efficiency, and new RPM service lines for HF/HTN management.
UCM's results show what this looks like in practice. The hospital reviewed more than 73,000 reports through Rhythm360 in 2025, averaging over 18,000 per quarter. Dr. Upadhyay confirmed: "We have improved billing and accountability for our patients after the integration."

The table above covers the core feature set. A few additional factors shape how well a platform fits your practice long-term.
Implementation timeline. Rhythm360's onboarding, including EHR integration, takes a few days to a few weeks. This minimizes disruption to existing clinical operations.
Pricing flexibility. Rhythm360 uses a SaaS-based pricing model that scales with clinic size and platform usage. This avoids the high setup fees and rigid contracts common in legacy systems.
AI triage performance. Alert triage needs to reduce fatigue without sacrificing reliability. Dr. Beaser at UCM noted: "Decision support, including AI-assisted decision support, will become increasingly important as data volumes grow."
