Multi-OEM device mixes now define most cardiology practices, and that reality strains legacy workflows. The moment a practice implants devices from more than one OEM, staff must log into separate, non-interoperable portals to retrieve patient data. This creates unsustainable administrative burden, data silos, and compounding clinical risk. 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.”
Staffing instability magnifies that strain. Gaurav A. Upadhyay, MD, FACC, FHRS, Professor of Medicine and Director of the Pacing & Defibrillation Device Clinic at UCM, stated: “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.” Alert fatigue from non-actionable notifications accelerates burnout, while fragmented documentation causes missed CPT revenue on codes such as 93298 and 99454. These problems appear in practice after practice, yet modern platforms now provide a path to resolve them.

Cardiologists rely on a range of cardiac implantable electronic devices (CIEDs) and wearable sensors that match specific clinical indications. Pacemakers and implantable cardioverter-defibrillators (ICDs) provide continuous rhythm therapy and remote telemetry. Cardiac resynchronization therapy (CRT) and cardiac contractility modulation (CCM) devices support patients with heart failure. Implantable loop recorders (ILRs) capture intermittent arrhythmias over extended periods. For hemodynamic monitoring, devices such as the CardioMEMS pulmonary artery sensor deliver continuous pressure data. Each device transmits through its manufacturer’s proprietary portal, which creates the fragmentation problem most practices now face.
No single wearable suits every patient or indication, so cardiologists match device type to monitoring goals. Short-term Holter monitors capture 24–48 hours of continuous data. Extended-wear patch monitors such as the Zio Patch record up to 14 days and improve detection of less frequent events. Consumer-grade smartwatches with ECG capability offer convenience but have limited clinical-grade sensitivity and documentation. For long-term, continuous monitoring, implantable loop recorders remain the gold standard for detecting paroxysmal atrial fibrillation and unexplained syncope. The critical workflow challenge does not come from the device itself, but from how that device’s data reaches the clinical team accurately and without delay. Platforms that aggregate wearable and implantable data into a single dashboard remove manual reconciliation work that consumes technician hours and introduces error.
Alert fatigue reduction in 2026 centers on AI-driven triage that filters non-actionable transmissions before they reach clinical staff. Instead of presenting every routine device check as an equivalent notification, modern platforms apply machine learning to stratify alerts by clinical urgency. Andrew Beaser, MD, at UCM, noted: “Decision support, including AI-assisted decision support, will become increasingly important as data volumes grow.”
Practices that layer optional 24/7 oversight from certified cardiac technicians (CCTs) on top of AI triage add a human checkpoint that further reduces noise reaching the on-call physician. This combined model keeps routine transmissions out of the physician queue while surfacing true exceptions quickly. Many practices report up to 80% faster response to critical alerts after adopting this approach.
Five capabilities define a platform that can address the pain points above in a unified workflow. First, vendor-neutral multi-OEM aggregation via API, HL7, XML, and PDF parsing eliminates portal fragmentation by pulling all device data into one interface. Once data is centralized, AI-powered alert triage becomes possible, which filters non-actionable transmissions and prioritizes clinically significant events before they reach staff.
This triage layer then supports automated CPT billing documentation, because the system already knows which events meet billable thresholds. Automated documentation captures codes 93298, 93299, 99454, 99457, and related codes without manual entry. Bi-directional EHR integration with systems such as Epic, Cerner, and Athenahealth closes the loop by sending this enriched data back into the patient record and removing duplicate transcription. A HIPAA-compliant mobile application extends the same workflow to any location, so clinicians can review transmissions and sign reports from their phones. Andrew Beaser, MD, at UCM, highlighted: “I am more likely to sign off on these while in meetings because I can easily access them on my phone.”
Practices evaluating any arrhythmia workflow platform should score each vendor across five clear criteria. Interoperability depth measures how many OEM data feeds the platform supports natively versus through manual PDF uploads. Onboarding timeline reflects how quickly EHR integration and staff training complete, measured in days to weeks rather than months. Staffing impact quantifies the reduction in technician hours spent on data retrieval and manual entry.
Compliance documentation assesses whether the platform auto-generates auditable records for every billable CPT event. Scalability evaluates whether the platform can handle high transmission volumes without degraded performance or latency. UCM processed more than 73,000 reports annually through Rhythm360 in calendar year 2025, averaging more than 18,000 reports per quarter, which illustrates what enterprise-scale performance looks like in daily operations.
The table below compares platforms across four objective capability dimensions. Outcome figures for Rhythm360 come from documented client results. Competitor capability assessments reflect publicly available product documentation, so practices should request vendor-specific outcome data during evaluation.

Rhythm360’s architecture targets each failure point in the legacy workflow with specific technical safeguards. Redundant data feeds, computer vision-based PDF parsing, and AI-powered extrapolation produce a transmissibility rate exceeding 99.9%. That reliability means critical device data still reaches clinicians when an OEM server experiences downtime. The AI alert triage layer shortens the path from transmission to action, which can reduce critical response times by up to 80% and shift teams from reactive to proactive management. Andrew Beaser, MD, at UCM, explained: “We are able to address these issues earlier; rather than waiting for a 3-month visit, we can call patients in for evaluation.”
On the financial side, automated CPT documentation removes the manual tracking that causes revenue leakage, which enables practices to capture up to 300% more revenue. Gaurav A. Upadhyay, MD, at UCM, observed: “We have improved billing and accountability for our patients after the integration.” The SaaS pricing model scales with clinic size and usage, and onboarding, including EHR integration, typically completes in days to weeks. Every outcome cited here can be reviewed during a live platform demonstration.
The primary CPT codes for remote cardiac device monitoring include 93298 for remote interrogation of an implantable cardiovascular monitor or loop recorder, 93299 for remote interrogation of a pacemaker or ICD, and 99454 for remote physiological monitoring device supply with daily recordings. Rhythm360 automates the documentation required to support each of these codes, tracking billable events, generating compliant reports, and maintaining an auditable trail for every patient encounter. This automation removes the manual tracking that causes missed claims and rejected submissions, which often drives revenue leakage in practices without a centralized platform.
Rhythm360’s onboarding process, including EHR integration setup, typically takes from a few days to a few weeks depending on practice size and the complexity of the existing EHR environment. The platform supports bi-directional integration with Epic, Cerner, Athenahealth, eClinicalWorks, Greenway Health, and other systems via HL7. Implementation follows a structured plan that minimizes disruption to active clinical workflows, and RhythmScience provides dedicated support so staff receive training and the system reaches full readiness before go-live.
HIPAA requires that any mobile application accessing protected health information (PHI) use end-to-end encryption, enforce role-based access controls, maintain audit logs of all data access events, and support remote wipe capabilities if a device is lost or stolen. Rhythm360’s mobile application meets these requirements and provides clinicians with secure access to transmissions, reports, and patient records from their smartphones. All communications and access events are logged within the patient record, which creates the auditable documentation trail that HIPAA mandates. Practices should confirm that any platform under evaluation provides a Business Associate Agreement (BAA) and documents its mobile security architecture before deployment.
Fragmented OEM portals, alert fatigue, missed CPT revenue, and staffing burnout do not have to define cardiology practice in 2026. These issues arise from workflows built around single-vendor tools that never anticipated today’s multi-device patient population. Vendor-neutral platforms with AI triage, automated billing documentation, bi-directional EHR integration, and mobile access now resolve each of these problems with measurable, verifiable outcomes. Rhythm360 is the platform with the documented results referenced earlier, including the UCM volume, up to 80% faster critical alert response, and up to 300% revenue lift, to support that claim.
