Market leading precision

Smartphone based cardiac monitoring

The Coala Heart Monitor is an award-winning and patient-engaged medical system for remote monitoring. The Coala connects wirelessly to a smartphone and captures ECG and heart sounds in just a minute.

Smart, cloud-based algorithms analyze instantly and detect for Atrial Fibrillation (based on P-wave detection and RR variability) and the ability to detect murmurs. Results presented to user and connected healthcare provider in seconds.

No more off-line sticky ECG electrodes, itchy patches or wires. The Coala has no limits in time or place and provides instant results and reports.

  • Ideal for detection of AF, palpitations and post-procedure follow-up in everyday life
  • Proprietary 2-lead ECG and integrated stethoscope powered by smart algorithms
  • Cloud-based analysis and HIPAA compliant data access

How it works


The patient simply holds the Coala against their chest for a 30 second ECG recording, followed by a 30 second thumb-ECG recording. Recordings can be performed anywhere, anytime in daily life. The heart sound is also recorded synchronously with the chest measurement.


The recording is sent encrypted and analyzed by Coala’s smart algorithms. Results are presented within seconds to the patient in the Coala App, and to the connected healthcare provider in the web-based Coala Care platform.


ECGs and the recorded heart sounds are instantly accessed in Coala Care, a web-based HIPAA compliant system. Easy to interpret the recordings and automatic analysis for AF, possibility to generate reports and communicate with patients remotely over time.

"We use the Coala for our cardiac assessments"

-We use the Coala as a connected event monitoring solution to help catch arrhythmias, screen for 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.

World-class clinical accuracy

So much more than a single lead AF detector

The Coala is an FDA 510(k) cleared system with strong clinical data. A Coala recording is made by simply holding the Coala for 30 seconds against the chest, followed by 30 seconds of thumb-ECG. The patent pending 2-lead ECG recording, and secure Bluetooth transmission maximizes quality, precision and accuracy - with less artifacts and need to redo the recording.

Coalas state-of-the-art algorithms analyze the ECG instantly based on P-wave detection and RR variability, unlike conventional AF screening solutions that typically only detect for RR variability.

"We use the Coala in 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 work flow, diagnosis of AF and threshold for prescribing anti-coagulants or ablations.

Digital cardiac assessments

Smart, cost-effective remote patient monitoring

The Coala is the next generation event monitor designed to engage the patient for better outcomes. It’s an effective monitoring solution as an alternative to short-term, off-line ECG-patches to enable arrhythmia assessments and in everyday life.

After recording an ECG, the results are displayed within seconds for the patient in the Coala App and for the healthcare provider in Coala Care, a system that can be accessed from any computer. Coala Care offers a clear overview of abnormal values without data overload. It enables further remote analysis, auscultation, ability to create PDF's, download raw data and communicate directly with Coala users.

With the Coala system you can save time and increase revenue, it’s HIPAA-compliant and designed to enable smarter assessments, improve healthcare productivity and profitability.

"Ideal for remote diagnostics"

- We use the Coala at the Karolinska Hospital to assess female hearts, to better understand their arrhythmias and confirm the diagnosis.

A unique solution for connected cardiac assessments

  • Patient-engaged event monitor with instant AF detection as well as murmur identification

  • Smartphone and cloud-based system and ideal for long-term remote monitoring

  • Proprietary 2-lead ECG-platform detecting AF based on RR-variability and p-wave.


Award-winning solutions for early detection of heart disease

The unique, multi-patented technology is based on more than 10 years of R&D. The Coala consists of a unique high-performance piezo sensor that records and digitizes the sounds of the heart, and with three integrated electrodes to quickly capture an ECG. The digital platform with 1.000 Hz, 24-bit ECG-technology delivers excellent high-quality ECG and analysis.
