300% more accurate than single-lead ECG
COALA is powered by a unique patented digital technology resulting in industry leading diagnostic-quality ECG.
The dual ECG recording with noise suppression maximizes quality, accuracy, and reduces artifacts. The smart algorithms detect AF based on P-waves and RR-dispersion leading to a significant reduced rate of false positives and increased overall accuracy.
The only smartphone system with P-wave based AF detection
The COALA is a CE and FDA 510(k) cleared device supported by strong clinical data with thousands of users. The chest-ECG with synchronized heart sound recording and thumb-ECG is transmitted via Bluetooth to maximize quality, precision and accuracy - with less artifacts and minimized false positives.
COALA’s smart algorithms analyze the recordings based on pattern recognition, P-waves and RR variability. Conventional 1-lead ECGs typically only detect AF based on RR variability, which result in high false positives. The COALA has been proven to be 300% more accurate than standard 1-lead ECG solutions, typically used in watches and other portable ECG’s.

Real-time reports
State-of-the-art 1,000 Hz and 24-bit ECG digital architecture and data analyzed by high-performance cloud-based platform.
The HIPAA-compliant Coala Care portal presents data in real-time to providers and includes a smart report generator with ability to manually annotate and download raw data for further analysis.
Published data has not only proved high sensitivity and specificity for the system, but also a PPV of 87% for automatic AF detection.
Synchronized ECG and heart sounds
COALA has an integrated stethoscope that captures heart sounds. During ECG recordings, the heart sound is recorded and synchronized with the chest measurement. The data is presented as a digital phonocardiogram (PCG) to aid the detection of murmurs.
Heart sounds can also be listened to remotely and downloaded from the Coala Care portal.

Industry leading capabilities
The COALA is designed for real-time remote monitoring of heart and lungs. Real-time ECG analysis with integrated stethoscope enabling remote auscultation of heart and lungs.
Prescribe as a 30-day Event Monitor or as a long-term Remote Patient Monitor (RPM) up to a year. No waiting for results with on demand ECG reports.
Ideal for telemedicine services with ability to enroll in the clinic or in the safety of the patient’s home.

Virtual cardiac diagnostics
The COALA is ideal to prescribe to patients with palpitations and intermittent symptoms of possible arrhythmias that need a long-term monitoring solution.
Its unique dual-lead ECG solution captures accurate, clinically relevant cardiac data when symptoms occur. It’s the only smartphone-based solution with automatic AF detection based on advanced pattern recognition algorithms.
The real-time visibility to results ensures physicians can efficiently progress symptomatic patients along the treatment path.
Remote Patient Monitoring
Enabling true real-time Telemedicine
Prescribe COALA as a short or long-term monitoring solution to help diagnose symptomatic arrhythmias or murmurs. No wires, No patches, No waiting for reports and No unexpected bills for the patient. Home enrollment is now available, read more here.
Recordings are easy to access with automatic interpretation and real-time reports in the cloud based Coala Care portal. As it’s fully reimbursed, the COALA ensures your team’s time is covered, and at minimum patient co-pay.

"We prescribe the Coala in our general practice"
- A key benefit of the Coala is that we have been able to empower patients, nurses and doctors around cardiac disease. The Coala is now a natural part of our workflow, diagnosis of AF and threshold for prescribing anti-coagulants or ablations.
Sara Banegas General Practitioner, Ekerö Vårdcentral, Sweden

Remote
lung auscultation
The COALA can also be used for remote monitoring of lung sounds from a patient’s home. The unique stethoscope and respiratory monitoring solution is available with support of FDA’s Emergency Guidance during the COVID-19 public health emergency.
Easy to enroll patient’s directly from their homes, eliminating the need of physical visits. Data is transmitted in real-time, making COALA ideal for Telemedicine use.

A unique digital solution addressing the needs of modern cardiology
Three reasons for the heart
For Event and long-term Remote Monitoring
The COALA is a unique 2-in-1 solution that can be prescribed as an Event Monitor (billed globally as CPT 93268) and/or used to follow patients long-term in RPM programs and billed monthly (CPT 99453, 99454, 99457 and 99458).
The COALA is available for Home Enrollment, where it’s shipped direct to the patient enabling virtual cardiac diagnostics and eliminating physical patient visits.

How does COALA work?
Connect via Bluetooth to a smartphone and simply hold the COALA to the chest for 30 seconds to capture ECG and heart sounds, followed by a 30 second thumb-ECG recording.
Smart algorithms analyze the recordings instantly. Results are available within seconds in the Coala app and to the healthcare provider in the Coala Care portal.


Clinically proven to improve quality of life
The COALA was used in the groundbreaking RedHeart Study by the Karolinska Institute (Stockholm, Sweden) and included nearly 1,000 women and over 280,000 ECG recordings in everyday life. The study showed an increase in quality of life in women with palpitations, because of the instant results that helped reduce symptoms, anxiety and depression.
The COALA is currently used in multiple clinical studies including the TEASE-study on cryptogenic stroke patients. The COALA is provided to patients to help detect AF post-admission for an extended period of time at home. Results to be presented in 2020.

Increase efficiency and patient satisfaction
"Enables me to efficiently follow every patient in their recovery"

"Enables me to efficiently follow every patient in their recovery"
– I’m proud to pioneer the first post-procedural protocol based on remote, patient-engaged monitoring with real-time analytics. Smart digital technology now enables me to efficiently follow every patient in their recovery, without burden or financial surprises for my patients. Dr. Reginald Abraham Chief of CardioThoracic Surgery and Chief of Staff Elect at Fountain Valley Regional Hospital, CA
"The ideal solution for modern cardiology"
– We’re proud to be the first major healthcare provider in the USA to introduce the Coala Heart Monitor on a broad scale for remote patient monitoring. The novel patient-centered solution with real-time response and abilities for long-term monitoring is the ideal solution for modern cardiology. Dr. Siva Arunasalam Cardiologist President of the High Desert Heart Institute
"To perfect the diagnosis of palpitations, especially on women"
- We use Coala at Karolinska to investigate women's hearts and ensure we give them the right diagnosis and treatment. Seniorprofessor Karin Schenck-Gustafsson Karolinska Institute, Stockholm, Sweden
"Accurate, real-time feedback reduces patient worries"
- We use the Coala as a connected event monitoring solution to help catch arrhythmias, diagnose AF and better understand the cause of palpitations. It offers excellent patient engagement and easy to use for typically 30 days. Of extra value is that it’s simple and fast to provide to the patient.

"For smart cardiac assessments"
- Heart palpitations and rapid heartbeats are often perceived as unpleasant and frightening. They are often harmless but there can sometimes be a treatable cause behind. Symptoms often come and go, making them difficult to catch, but with a Coala Heart Monitor you can record all symptoms whenever they occur, with high security and good clinical quality. This makes it easier for you and for your healthcare provider to manage your heart. Åke Olsson, MD Cardiologist CEO of Sturebadet Healthcare, Sweden
"Ideal for long-term remote cardiac monitoring"
- The Coala Heart Monitor is a valuable addition our solutions for investigation of heart rhythm disorders. As symptoms of heart rhythm disorder can be diffuse and intermittent, the Coala is ideal to detect or dismiss non-persistent rhythm disorders, powered by the patient. Peter Magnusson, MD Senior physician and Cardiologist Region Gävleborg, Sweden
