Five of the best EHR systems for cardiologists. Updated: 8th October 2026 As of this article's last update, cardiologists have increasingly been looking for systems tailored to their specialty, seeking out features that can handle the unique aspects of cardiac care such as imaging, stress tests, EKGs, and other cardiovascular diagnostics. Here is a look at five of the best cardiology-specific EHR systems currently available, as well as an update on existing entries. Merge Cardio. Merge Cardio is Merative's cardiology-specific, web-based EHR that ranked in the top 3 for cardiology monitoring/systems in the 2026 KLAS report. Merge Cardio offers a centralized and easily accessible web-based view of a patient's complete record from all cardiology modalities. It also includes a sophisticated automated billing function that can increase the speed of reimbursements. The system remains a top choice among cardiology EHR software options, with recent updates focused on enhancing interoperability and user experience: * AI-enhanced diagnostics: Includes tools that assist in interpreting diagnostic imaging, potentially reducing error rates and enhancing decision-making. * Improved user interface: Updates to the UI have made it more intuitive, reducing training time for new users and increasing overall efficiency. * Merge Cardio 12.5 includes FDA-cleared AI-generated echocardiogram measurements integrated from partner Us2.ai to reduce variability and streamline clinical workflows AdvancedMD (Replacing NueMD). NueMD will reach its end of life at the end of 2026, as AdvancedMD phases out the platform and its support in favor of the vendor's own, highly integrated, cloud-based platform that combines EHR with practice management software. The transition from NueMD to AdvancedMD offers enhanced features, including: * Improved cardiology-specific templates: Customizable templates tailored for cardiology, including EKG interpretations, stress test reports, and imaging results. * Comprehensive practice management: Features a full suite of tools including billing, scheduling, and reporting. * Integrated telehealth services: Built-in telemedicine capabilities to support remote patient consultations, increasingly crucial for follow-up in chronic cardiac care. Migrating to AdvancedMD could offer smoother workflows and better integration with diagnostic tools. Objective Medical Systems (OMS EHR). Objective Medical Systems' cloud-based, cardiology-focused EHR has 16 reporting modules for all popular diagnostics. It also has the ability to interface with a cardiologist's diagnostic equipment so that results may be viewed directly within the EHR without any scanning or manual document management required. OMS EHR continues to lead with its cardiology EHR software that interfaces seamlessly with diagnostic equipment. Recent updates include: * Enhanced reporting modules: OMS integrates with a broad range of cardiovascular diagnostic tools, providing comprehensive support for key diagnostic modalities such as Holter monitors, echocardiograms, and stress tests. * Integration with wearable devices: Supports integration with patient wearable devices, enabling real-time monitoring of vitals such as blood pressure and heart rate directly into the EHR system. * AI-driven insights: The system incorporates advanced AI features through its platforms such as Cardiolytica(TM) and Trace Analytics. These tools deliver predictive analytics and clinical decision support, helping identify patterns in patient data. For instance, AI capabilities can predict issues like diastolic dysfunction from EKG results and assess the likelihood of patient no-shows. drChrono. drChrono's cloud-based patient care platform offers practices the ability to customize the EHR's interface and functionality at the point of care and through its mobile applications available on iPad, iPhone and Apple Watch. drchrono also includes scheduling, billing, and patient reminders. An interesting feature included in the drChrono system is its patient portal module which allows providers to maintain constant communication with patients and allows easy communication of patient data such as daily blood pressure readings. drChrono has remained a strong contender in the cardiology EHR market due to its flexibility and user-friendly design. Recent enhancements include: * Enhanced mobile access: Continued improvements in its mobile apps for iPad and iPhone, facilitating easy access for cardiologists on the go. * Improved patient portal: The updated patient portal now offers more robust features, including secure messaging, appointment scheduling, and the ability to upload patient health data from wearable devices. athenaOne Cardiology EHR. The athenaOne Cardiology EHR provides cloud-based services with integrated revenue cycle management, medical billing, patient engagement, care coordination, and population health management, as well as point-of-care mobile apps that integrate with the main EHR. Athena's system also allows providers to collect, analyze and generate reports on the quality of care and other patient data. Athenahealth has solidified its position as a leader in cardiology-specific EHR software, with a focus on integration and patient engagement. * Revenue Cycle Management: Athenahealth was recognized for its revenue cycle management (RCM) in 2020 when Frost & Sullivan named it the RCM company of the year. The award was given in recognition of Athenahealth's leadership in solving RCM challenges and providing agile solutions during the COVID-19 pandemic. * Expanded mobile app features: "Hey athena" activates cloud-based, voice-enabled skills in the athenaOne app for hands-free task completion and increased efficiency. Many clinicians using a voice assistant have saved significant documentation time, allowing them to focus on other high-priority tasks.

Truven has launched MarketScan Snapshot, an AI-powered tool that enables users to assess real-world healthcare data in minutes using plain language queries. The capability allows researchers to explore MarketScan Research Databases without programming experience or medical coding knowledge. MarketScan Snapshot addresses a significant time bottleneck in real-world evidence research. "The real-world evidence community can spend days or even weeks just getting to an initial answer on whether a cohort exists," said John E. Linnehan, Truven's vice president and head of real-world data. The tool returns patient counts and summary statistics dashboards to help teams evaluate cohort feasibility quickly. The platform accesses MarketScan's longitudinal closed-claims data, which includes over 300 million cumulative lives, 95 million active lives, and 99% claims completeness, with records dating back to 1995. Complimentary access is available to qualified organisations evaluating the MarketScan Research Databases.
