Remote Medical Monitoring & TeleRehabilitation Platform

Remote Medical Monitoring & TeleRehabilitation Platform
Our physician-led innovation, powered by the 4i4 IT team
Problems: Critical Gaps in Outpatient Care
Cardiovascular disease: still the world’s leading cause of death and disability.
Post-Myocardial Infarction & Surgery
Patients recovering from heart attacks or cardiac surgery are highly vulnerable post-discharge, often lacking sufficient follow-up.
Stroke of Unknown Cause
Many strokes are driven by hidden arrhythmias. Prolonged ECG monitoring is missing in current care pathways.
Under-treated Arrhythmia
Conventional rhythm monitoring leaves dangerous blind spots. This results in missed arrhythmias, delayed diagnosis, and suboptimal treatment, putting patients at risk of stroke and heart failure.
Cardiac Conditions in Professional Athletes
Athletes use ECG wearables, but fitness-focused algorithms often miss early arrhythmias and hidden cardiac conditions that surface under intense training.
Cardiac Rehabilitation in CEE
<20% of patients access rehab after heart attack or surgery (vs. >60% in Western Europe).
Limited centers & capacity
Low adherence due to travel, cost, and poor continuity after discharge.
Younger cardiac patients avoid inpatient rehab due to work, family, and lifestyle constraints.
Telerehabilitation is underdeveloped.
Result: higher readmissions, worse recovery, and avoidable healthcare costs.
Our Digital Solution
We deliver a connected, specialist-driven platform that bridges the post-discharge gap through:
Continuous Remote Monitoring
Prolonged Holter electrocardiography and wearable device integration for early arrhythmia detection.
Specialist-Guided Follow-Up
Structured vital parameters tracking and direct communication with specialists, ensuring timely interventions and personalized care.

Telerehabilitation
Scalable, cost-efficient and clinically validated rehabilitation programs delivered remotely or through a hybrid model.
Athlete-Specific Monitoring
Medical-grade interpretation of wearable data to detect hidden cardiac risks, support safe return-to-play, and optimize performance.
GDPR-Compliant & AI-Ready
Our platform ensures robust data security and GDPR compliance, built on an open API for seamless integration. The platform is AI-ready, enabling future development of predictive analytics that can identify health risks early, trigger automated alerts, and support more efficient clinical decisions - creating strong potential for added value and scalability.
What Our Platform Can Do:
Supporting the full patient journey from acute post-event care, through rehabilitation, to long-term management
Connecting with Care: Patient Profile
Specialist Access - Patients can find relevant experts in their area on a map and schedule appointments on a calendar.
Integrated Health Data - Syncs with Apple Health, Google Fit, and other sources; combined with manual input and PROMs for comprehensive visualization and secure sharing.
Medication Diary with automated reminders to support adherence.
Validated ECG Strips - Upload ECG strips from smartwatches for medical-grade interpretation, going far beyond standard automated alarms.
Empowering Care: Physician Profile
Practice Visibility - Physicians can set their location and appear on the map, making it easy for patients to find and reach them.
Appointment Management - Integrated calendar for scheduling and coordination.
Health Data Visualization - Structured display of all shared patient data.
ECG Review - Access ECG and provide medical-grade conclusions.
Prolonged ECG Monitoring 
Validated Telerehabilitation - Conduct evidence-based remote rehabilitation programs.
Extending Beyond Patients: Athletes & Healthy Individuals

Why Our Platform Stands Out in CEE
Healee: Teleconsultation & Workflow
Healee is a Bulgarian white-label general telehealth platform, strong in virtual workflows. Our Platform offers the same core functions – EHR integration, teleconsultation, chat, and scheduling – but adds a specialized focus on arrhythmia detection, stroke prevention and rehabilitation tailored to cardiovascular patients.
Telios Care: 24/7 General Telemedicine
Romanian/Bulgarian platform offering general emergency consultations, but does not offer specialized care, rehabilitation programs, or long-term monitoring.
Check Point Care: Acute Remote Monitoring
Bulgarian scale-up offering real-time ECG and vital sign streaming with AI-driven alerts, validated in large-scale deployments (70k+ patients). Highly effective for acute surveillance, particularly in hospital or transitional settings. However, its scope remains focused on monitoring, with limited integration for long-term follow-up, patient engagement, or structured rehabilitation pathways.
Medo / eDoktor24 (General): Broad Platforms
These broad CEE telemedicine platforms offer general services but do not possess the specialized care features essential for high-risk patients.
Why We’re Better:
A specialized, cardiology-centered approach – not just another generic telemedicine app.
A complete patient journey – from post-acute follow-up to long-term care.
Integration of sports and preventive health, rarely found in other platforms.
Built on a solid clinical foundation, not just pilot programs, with initiatives already running in Czechia  and Bulgaria
