“Check je hartritme” is now live in 6 Dutch cardiology hospitals. Aligned with ESC/EHRA #PulseDay2026, posters link AF awareness to action: scan the QR code to access smartphone PPG heart rhythm assessment in the @Luscii1 app, powered by Happitech.

Selected Dutch🫀hospitals will run the “Check je hartritme” campaign (2–15 March), led by Dr Stefan Timmer and Quinta Steenbergen @noordwestzh supported by @Luscii1 & Happitech. Smartphone PPG AF screening plus clearer GP follow-up aims to shorten time to AF diagnosis.

Happitech turns a smartphone camera into a clinically validated PPG tool for AF monitoring. Patients get at-home readings between appointments. Health systems get CE-marked, hardware-free monitoring that integrates with RPM and virtual care for scalable follow-up and triage.

At Noordwest Ziekenhuisgroep, cardiologists use Happitech's app (via Luscii platform) to support 🫀rhythm-based triage for cardioversion/ablation and post-treatment monitoring - reducing routine follow-ups while maintaining oversight in AF care.

What a great presentation by @HanFengGHD on using #AI to personalize #AF care - Using prediction to better prevent progression of AF, for early and personalized treatment post ablation - will help us to know who might recur, when and how best to treat! #WAFib2025

Truly an honor to have shared the stage with giants in the field. Post-ablation AAD strategy is under investigated, an area that should be given more consideration in future studies. @jobrachmann @mbelshazly @drjohnm @JonHsuMD @jhurwitz55 @deering_f @nmarrouche

In anticoagulated patients with #AFib, bleeding was strongly associated with new cancer diagnoses. Timely investigations after 🩸is of essence and should not be considered an expected adverse effect! 👏@husam247 @CircAHA @JacopoImberti
