“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.

Post #Afib #Ablation, how do you monitor for recurrence?

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.

Advancing cardiac research with smartphone-based monitoring.

Happitech’s FastStart app turns smartphones into a CE-certified, TGA-approved tool for remote AF, heart rate and HRV measurements, supporting scalable, real-world studies across the EU and US. #digitalcardiology

PPG is at the heart of Happitech’s smartphone-based cardiac monitoring. We will be at ESC Digital & AI Summit 2025 in Berlin (21–22 Nov) and would like to meet researchers and innovators working on PPG, digital biomarkers and AI in cardiology. #ESCAIsummit2025 #ESC

Survivors of ischemic #stroke face a high risk of early heart complications (within 4 weeks):

👉11.1% develop #ACS
👉8.8% #Afib
🚨Early monitoring is critical!

📍Join us at #EHRA2025 in Vienna!

We’re advancing AF research with our clinically validated, AI-powered smartphone app - already used in studies across the EU, UK & USA.

Let’s connect if you're exploring digital tools for remote heart rhythm monitoring.

[Hadi Younes, MD @SinusAtria]

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

Great presentation by my colleague and friend @BidaouiGhassan explaining the interplay between sleep apnea and AF at #WAFIB2025 @nmarrouche @TulaneTriad

[Mayana Bsoul @BsoulMayana]

Great presentation by our own @MassadChristian, diving into the complexities PFA assessment.
Always pushing the boundaries of understanding! @nmarrouche @tulanetriad #WAFib2025 @westernAFib #EPEEPS

30d-monitor sensitivity= 60%

#TelecheckAF asked pts to do #smartphone #PPG post ablation: avg’d 20 PPGs/week!

But compliance ⬇️ w/ ⬆️ duration/frequency of monitoring

#Smartwatch PPG algorithms could allow for 56 “pulse checks”/day *passively*!

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!

[ESC Council on Stroke Chairperson @ESCStrokeChair]

In pts w/ subclinical #Afib & prior stroke/TIA enrolled in @Artesia_RCT, apixaban ⬇️ stroke/systemic TE risk by 7% over 3.5 yrs vs. ASA (1% in those w/o prior stroke/TIA). Major bleeding risk ⬆️by 3%
