On 22 April, Happitech will join the 2026 Stanford Biodesign New Arrhythmia Technologies Retreat in Chicago. CEO @ysharb and team will present our approach to smartphone-based heart rhythm monitoring and medtech innovation. #StanfordBiodesign #AtrialFibrillation #Arrhythmia

“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? #WAFib2026 #EPeeps @westernAFib @nmarrouche

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

@HadiiYounes @EmoryDeptofMed @EmoryUniversity @emoryimchiefs @nmarrouche Congrats @HadiiYounes wishing you lots of success everywhere you go.

Truly an honor to have matched at @EmoryDeptofMed @EmoryUniversity @emoryimchiefs for my internal medicine residency. Looking forward to becoming part of the Emory family. Super grateful to my mentor @nmarrouche for the constant support and guidance.

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! Read more🖇️ tinyurl.com/429kd6w6 #StrokeHeartSyndrome #ESCstroke @JacopoImberti @LiverpoolCCS

SMURDEN (Smartphone-based AF Burden) as a powerful marker for quality of life, symptom severity, and predicting recurrence post-ablation presented by @nmarrouche @Charbelnoujaim @TulaneTriad #StanfordBiodesign2025

Thank you @Wanginnovate @S_NarayanMD for the invitation to speak on the “Future of Digital Arrhythmia Care” at #StanfordBiodesign2025! I am honored to be included in this in truly outstanding, fast & furious, forward-thinking conference! #WomeninEP #HRS2025

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.

📍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. #EHRA2025 #mHealth

A force in #CardioVascularAI

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

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*! @PassmanRod #WAFib2025

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

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% 🖇️tinyurl.com/4js6nsu5 @WFMMD @PHRIresearch @BorianiGiuseppe
