Our work out today in @AnnalsofIM shows the importance of systematic follow up for patients with so-called “secondary” or “peri-operative” #AtrialFibrillation. 1 in 3 will have AF recurrence when assessed with 14 day Holter @McMasterU @PHRIresearch

[Annals of Int Med @AnnalsofIM]

Patients with new-onset atrial fibrillation during hospitalization face a surprising 1 in 3 risk of AF recurrence within 1 year, according to a new study. Findings highlight importance of vigilant monitoring and care. https://t.co/s5sSDLUzaE #AtrialFibrillation #HeartHealth

Annoying hit that causes the infield to lose braincells? Ernie clement is there

Go ahead ridiculous HR off a nearly unhittable pitch location? Ernie clement is there

Platinum glove, cooperstown plays in the infield? Ernie clement is there

Monster playoff performance off every Yankee pitcher? Ernie clement is there

Sleep paralysis demons hovering over my chest? It’s Ernie clement

Dying in a hospital bed when I’m old and sick? Ernie clement is the nurse

Ernie clement today
Ernie clement tomorrow
Ernie clement forever

[William F McIntyre @WFMMD]

For a patient with new-onset trigger-associated #AF, how long do you need to monitor them in follow-up to find recurrent AF?

@drjohnm We should start to talk about non-inferiority, though. What’s the margin and why? And if we include all-cause deaths, we will have non-arrhythmic deaths (non modifiable by ICD) in the primary endpoint and bias to the null. @AlexanderPBenz

@BA_Mulder @ChristianHeeger @Dominik_Linz @EHRAPresident @simovicst @micaela_ebert I was able to fill this during my first hour on Congress. Spectacular work. Surprise thing missing: edible coffee cups. Phrase we could have had on card: “do you have data on AF burden?”

Very proud to have been part of this project. A very practical application of AI that should ultimately make diagnostics ambulatory ECG more accessible to patients.

[Linda Johnson @lsjMD]

Everyone with an interest in AI, ECGs, or cardiology should read our paper out in Nature Medicine today! The DRAI MARTINI study tested the performance of DeepRhythmAI from #MEDICALgorithmics for direct-to-physician reporting of ambulatory ECGs. The results overwhelmingly favour the AI, with 14 times fewer missed diagnoses of critical arrhytmias.

Read it here: https://t.co/jhlIRSL4Qu

Here's the study in brief:
🏥 >200,000 days of ECGs from >14,000 patients
🩺 >50 experts provided 3-cardiologist beat-to-beat consensus panel annotations of >5,000 ECG events
🖥️ Innovative study design provides absolute rates of missed diagnoses of AF or SVT ≥30s, 3rd degree block, 3.5s asystole or >10s VT

Results:
🫀Missed diagnoses in 3.2/1000 patients by DeepRhythm and 44.3/1000 patients by techs
🫀Superior sensitivity (98.6% vs 80.3%)
🫀NPV >99.9% for DeepRhythmAI.

This study is the result of an awesome collaboration with true leaders in the field who not only gave their scientific expertise but also committed many hours of their own time doing beat-to-beat annotations of >5,300 ECG events, with consensus annotation on every single beat. This resulted in an impressive author list including @EmmaSvennberg @SZDiederichsen @DrJasonAndrade @WFMMD @AlexanderPBenz @EPjeff17 @PlatonovPyotr @StavrosStavrak1 @Cardiaficionado @Dominik_Linz @JuanBenezet @PhilippKrisai @SanjeevBhavnani @AlirezaOraii @ManningerMartin and many more!
