Consultation, diagnosis and treatment same day, latest same week

Heart in Focus, Patient First

“The first step when optimising one's health is to quantify risk."
Over more than 30 years of research and clinical experience, we have seen time and again how prompt intervention is crucial for optimal outcomes. That is why our goal is for you to be seen, examined, and diagnosed, and to begin treatment without unnecessary delay – if possible, on the same day.

As the saying goes, "An ounce of prevention is worth a pound of cure."

By integrating cardiology and advanced diagnostics, our doctors can make quick decisions. If we discover something during an examination that requires further investigation, we aim to take care of it immediately. If you want to optimise your health and prevent problems long before they arise, we look to provide you with answers, and a programme, right away.

This approach saves time and resources – including your time and your money – spares you from waiting in uncertainty, and leads to better clinical outcomes.

At eHeart, every patient journey is unique, tailored to the individual's specific needs to make the experience as safe, efficient, seamless and reassuring as possible.

We look forward to hearing how we can help.

eHeart takes the next step in our tailored expertise: now we're double ISO certified

eHeart is now certified to both ISO 9001:2015 (quality management) and ISO 14001:2015 (environment).

ISO certification requires significant resources: time, skills and financial commitment. Many healthcare providers choose not to make that investment. We made a different choice, because we believe you as a patient deserve evidence, not just promises. That's why we've spent thousands of man-hours building systems that ensure we keep promises we make.

Offering the market's leading specialist care takes more than ambition. It takes proven, continuous quality. That's why we're proud that eHeart AB has now been awarded two major international ISO certifications from AAA Certification AB (“A3CERT”), clear proof of our uncompromising commitment to patient safety, precision and sustainability.

Our certifications are specifically issued for our core business: providing specialized cardiovascular consultations and care, as well as advanced clinical physiological diagnostics.

For you as a patient or partner, this means two important guarantees:
ISO 9001:2015 (Quality Management):
We have been quality certified since 27 August 2026. This means our processes, from your very first visit at our clinic at Sophiahemmet on Valhallavägen in Stockholm, to advanced diagnostics and follow-up, are governed by strict international requirements for quality and continuous improvement. Your peace of mind is built into every step of our work.
ISO 14001:2015 (Environmental Management)
Our care extends beyond the individual. As of 27 August 2026, we are also environmentally certified, proof that our operations are conducted with the greatest possible consideration for our surroundings and the future.
eHeart AB’s management system has been certified (number 3169) to ISO 9001:2015 (quality) and ISO 14001:2015 (environment) standards by A3CERT. A3CERT holds accreditation number 1939 for ISO/IEC 17021-1 from Swedac Ackreditering.

For us, this is not a finish line, but confirmation that our daily work makes a difference. Through our tailored expertise, we continue to lead the way forward, for your heart, your wellbeing, and the future.

History — eHeart through the years

Rosa neonglödande pulslinjer och EKG-vågor på blå och lila bakgrund
eHeart is founded to finance and develop medical technology.
The inaugural project is EchoReporter, a software designed to support medical professionals in their analysis of ultrasound images of the heart, lungs and blood vessels. This pioneer spirit is at the core of eHeart's DNA today.

Continued development of EchoReporter and technical infrastructure.
The team is working intensively to refine the EchoReporter platform and build the technical foundation for future healthcare operations. Partnership talks are initiated with healthcare providers in the Stockholm region.

Under the leadership of Dr. Reidar Winter, eHeart begins to offer care to patients in the Stockholm region.
With its background in university hospitals, Reidar strives to combine high-quality care with the patient experience possible in a small clinic. eHeart supports other healthcare providers in the Stockholm region, including Södertälje, and begins construction of the clinic at Hötorget, Norrmalm, Stockholm. The development of EchoReporter continues.

The Covid-19 pandemic — eHeart is gearing up to help.
In April 2020, the team shifts focus to fighting Covid-19. With funding from philanthropists, eHeart buys antigen tests and donates services to test 12,000 healthcare workers in Stockholm. Despite the pandemic, the core business of cardiac diagnostics continues.

eHeart moves to Sophiahemmet in Norra Djurgården, Stockholm.
The new facility provides opportunities for expansion and collaboration. eHeart continues to serve private patients directly and also offers Sophiahemmet's other caregivers cardiac and other diagnostic services. Operations expanded to include sleep apnea diagnostics and treatment. Investments in in-house technology are accelerating to manage the growing business.

Significant investments are made in modern equipment, digital infrastructure and, above all, in the team. Members from many different countries join, and the clinic can now offer care in Swedish, English, Finnish, Spanish, Hungarian, Russian, Ukrainian, Turkish and Persian.

eHeart is opening a second clinic at Östermalmsgatan 47 (Engelbrektskliniken) to increase accessibility in central Stockholm. Work is underway to implement ISO standards for quality management (ISO 9001) and information security (ISO 27001) — a major effort that requires extensive process and system documentation.

We welcome patients who have private health insurance or who choose to pay directly for their care. We continue to invest in time- and labor-saving technologies to enable our clinicians to spend as much time as possible doing what we're good at: caring for you.

ISO certification process intensifies
eHeart begins the intensive final stage of ISO certification work according to both ISO 9001:2015 (quality management) and ISO 14001:2015 (environment), as well as accelerating compliance with ISO 27001:2022 (information security). Extensive process and system documentation is carried out, and the entire organization prepares for the external audits. With a growing clinic and team in Stockholm eHeart continues to offer fast access to high-quality cardiac care.
