Once a cardiology practice implants devices from more than one manufacturer, staff must maintain separate logins across non-interoperable portals. The operational consequences compound quickly. An international survey of 471 device clinic staff across 44 countries found that 42% rated their staffing as somewhat or very insufficient for remote monitoring demands, and the three most burdensome tasks were managing disconnected patients, initial transmission review, and patient phone calls.
Alert fatigue grows in parallel with this workload. In a cross-manufacturer analysis of 2,659 rhythm episodes from 1,710 patients, 32.9% of episodes from AI-equipped devices were non-actionable and 30.6% were indeterminate. As Niraj Varma, MD, PhD, of the Cleveland Clinic, noted, “False-positive alerts remain one of the biggest operational challenges in remote cardiac monitoring. Every episode flagged by an implantable cardiac monitor must be reviewed by a clinician, yet even devices equipped with manufacturer AI algorithms still generate a substantial number of non-actionable alerts.”
Financial leakage follows this clinical overload. A 500-patient cardiology RPM program leaves more than $400,000 per year on the table when the 20-minute rule, 16-day transmission rule, and 90-day device interrogation cycles are tracked manually. Many clinics do not measure remote monitoring program performance in a structured way, so most practices lack a baseline to identify or recover that leakage.
Schedule a demo to see how Rhythm360 consolidates your CIED workflows into one platform.
The following sections outline six core capabilities that distinguish an effective care team empowerment platform from fragmented OEM portals, starting with vendor-neutral data ingestion.
A cardiology practice that manages devices from Medtronic, Boston Scientific, Abbott, Biotronik, and others cannot operate efficiently when each manufacturer requires a separate login, separate data review, and separate documentation workflow. A care team empowerment platform must ingest and normalize data from all of these sources into a single dashboard.
Rhythm360 achieves this through a multi-layered ingestion strategy. API connections and HL7 messaging handle structured data from modern OEM systems, while XML parsing and AI-powered computer vision extract information from unstructured PDFs, which many OEM portals still use for transmission reports. When an OEM server experiences downtime, a redundant data feed system takes over, which supports Rhythm360’s greater than 99.9% transmissibility rate. University of Chicago Medicine reviewed more than 73,000 reports annually through Rhythm360 in calendar year 2025, averaging more than 18,000 reports per quarter, which demonstrates the platform’s scalability across a high-complexity, multi-manufacturer device population.
Unfiltered, non-prioritized alert volume drives alert fatigue and delays care. An effective care team empowerment platform applies AI triage that surfaces clinically significant events while suppressing non-actionable noise, without sacrificing sensitivity for true emergencies.
Rhythm360’s AI triage engine prioritizes alerts by clinical severity so teams can act on the events that matter most. Practices using Rhythm360 have documented sharply faster response times for critical alerts. A common scenario involves a Saturday-morning arrhythmia flag, such as new-onset atrial fibrillation detected remotely, that leads to the patient receiving anticoagulation therapy that same afternoon. Without a prioritized, mobile-accessible alert system, that event might not surface until the next business day or a scheduled three-month visit. As Andrew Beaser, MD, Associate Professor of Medicine at University of Chicago Medicine, explained, “We are able to address these issues earlier; rather than waiting for a 3-month visit, we can call patients in for evaluation.”
Dr. Beaser also noted that “Decision support, including AI-assisted decision support, will become increasingly important as data volumes grow.”
Manual transcription of device data into the EHR drives documentation errors and staff burnout. Diagnostic results should flow into patient records in structured format, not as scanned attachments, and should trigger automatic follow-up tasks for cardiology care teams. A platform that requires staff to re-enter data from one system into another adds both error risk and time cost.
Rhythm360 offers bi-directional EHR integration with Epic, Cerner, Athenahealth, eClinicalWorks, Greenway Health, and additional systems via HL7. Data flows in both directions. Device transmissions populate the EHR, and patient demographic or scheduling updates in the EHR appear in Rhythm360. The onboarding process, including EHR integration setup, typically takes from a few days to a few weeks, which is substantially faster than the 8-to-16-week timelines associated with full EHR platform implementations.
Patient follow-up in CIED monitoring programs consumes significant staff time. Teams spend hours on calls to reconnect disconnected devices, send reminders for scheduled transmissions, and coordinate after abnormal findings. Without a documented communication log, practices face compliance exposure and duplicated effort.
Rhythm360 integrates a Twilio-powered messaging framework that supports both automated and manual patient outreach. Every communication, including phone call logs, is recorded within the patient record with a full audit trail. A medical assistant reviewing a patient whose heart failure scale has been disconnected can see the automated reminders already sent before making a personal call. This visibility eliminates redundant contact and maintains a complete, auditable record of all care coordination activity.
Cardiology practices differ in their internal staffing capacity. Some have dedicated device technicians available during extended hours, while others need external clinical support to ensure no transmission goes unreviewed. A care team empowerment platform should support both models.
Rhythm360 offers optional 24/7/365 oversight by certified cardiac technicians supervised by physicians, which gives practices a scalable safety net for after-hours and weekend transmissions. For clinicians who prefer to manage reviews internally, the secure, HIPAA-compliant Rhythm360 mobile app provides access to transmissions, report signing, and care coordination from any location. Dr. Beaser at University of Chicago Medicine described his own use of this capability: “I am more likely to sign off on these while in meetings because I can easily access them on my phone.”
CPT billing for remote cardiac monitoring is time-sensitive and rule-dependent. The 90-day interrogation cycle for CIED codes, the 16-day transmission threshold for 99454, and the 20-minute time requirement for 99457 each create compliance checkpoints that manual tracking routinely misses. This gap is particularly costly for 99457, where practices often fail to document the 20-minute threshold even when staff time qualifies, which leaves billable units uncaptured on complex cardiac patients.
Rhythm360 automates CPT code capture and documentation across 93298, 93299, 99454, 99457, and related codes. The platform tracks thresholds upstream and generates compliant documentation at the point of clinical activity. Practices implementing Rhythm360 have documented substantial revenue increases from this automation. Gaurav A. Upadhyay, MD, at University of Chicago Medicine, confirmed, “We have improved billing and accountability for our patients after the integration.”

Most cardiology practices go live with Rhythm360 in a few days to a few weeks, depending on size and system complexity. This timeline covers data source connections to all relevant OEM portals, bi-directional EHR integration, staff onboarding, and configuration of alert thresholds and billing rules. The process is designed to minimize disruption to ongoing clinical operations, and RhythmScience provides dedicated implementation support throughout.
Yes. The Rhythm360 mobile application is built to HIPAA compliance standards and provides clinicians with secure access to patient transmissions, report signing capabilities, and care coordination tools from their smartphones. All data transmitted through the mobile app is encrypted, and access is controlled through authenticated user credentials. This setup allows electrophysiologists, cardiologists, NPs, PAs, and device technicians to review and act on critical alerts from any location, including evenings, weekends, and time between appointments, without compromising patient data security.
Practices implementing Rhythm360 have documented significant revenue increases from more complete and compliant billing. This improvement results from several compounding factors: automated tracking of CPT billing thresholds that manual workflows routinely miss, compliant documentation generated at the point of clinical activity, and the addition of new RPM service lines for heart failure and hypertension patients that generate recurring monthly reimbursement. University of Chicago Medicine specifically noted improved billing and accountability following Rhythm360 integration. The platform’s billing automation captures codes including 93298, 93299, 99454, and 99457, and enforces the 90-day interrogation cycle, 16-day transmission threshold, and 20-minute time requirements that are primary audit triggers under current OIG scrutiny of Medicare RPM payments.
Rhythm360’s AI triage system filters non-actionable transmissions and ranks remaining alerts by clinical severity before presenting them to the care team. Instead of surfacing every device communication at equal priority, the system distinguishes between routine scheduled transmissions, low-acuity findings, and high-priority events such as new-onset atrial fibrillation, ventricular tachycardia, lead malfunction, or ERI/RRT indicators. Clinically significant events are escalated immediately, including on weekends, which enables same-day interventions that would otherwise wait for a scheduled office visit. For practices that require additional coverage, the optional 24/7 CCT oversight layer provides certified cardiac technician review of all transmissions, supervised by physicians, so no critical event goes unaddressed regardless of time of day.
Fragmented OEM portals, manual billing workflows, and siloed data systems create a compounding burden on cardiology teams. The result is administrative overload, alert fatigue, missed critical events, and recoverable revenue that never gets captured. A care team empowerment platform purpose-built for multi-manufacturer cardiology workflows addresses each of these failure points within a single, unified system.
Rhythm360 delivers vendor-neutral data ingestion across major device manufacturers, AI-powered alert triage that shortens critical response times, bi-directional EHR integration with the systems cardiology practices already use, Twilio-powered patient communication with a full audit trail, optional 24/7 CCT oversight, a HIPAA-compliant mobile app, and automated CPT billing documentation that supports the revenue improvements detailed earlier. University of Chicago Medicine’s experience, with high-volume report management and earlier interventions alongside stronger billing, shows what this platform can deliver at scale.
