I wrote a short interactive article👆

It uses simulations to demonstrate how different cardiac arrhythmias can develop.

Try it out! (It has defibrillators ⚡️)

Yes, just curious re the axis/transition which fused with fig. 3 to make fig 1&2

Very nice. How'd the intrinsic look?

Biventricular Paced QRS Area Predicts Acute Hemodynamic CRT Response Better Than QRS Duration or QRS Amplitudes Introduction Vectorcardiographic (VCG) QRS area of left bundle branch block (LBBB) predicts acute hemodynamic response in cardiac resynchronization therapy (CRT) patients. We hypothesized that chang.....

Very cool! Any thoughts on an RV pacing control? Would also be interesting if QRS area better corresponded to the metabolic effect of CRT as it does with hemodyanmics

Symptoms of gastroesophageal reflux disease predicts low voltage zones in the posteroinferior left atrium in patients with persistent atrial fibrillation The presence of low voltage zones (LVZs) in the left atrium (LA) is associated with the recurrence of atrial fibrillation (AF) after pulmonary vein is…

Have seen the same with patulous esophagus. Have a CT? www.sciencedirect.com/science/arti...

Interesting early experience for MR guided radiotherapy for refractory septal VT. #EPeeps #CardioSky

LA/RL makes III across the legs which is low but not no vector. If II=-III then aVF is 0.

#EPeeps Okay I thought I knew all the limb lead reversal patterns, but what madness is this?

I believe the math works if the limb leads lie in (or nearly in) the same line with LL midway between LA and RA so that II and III are mirror images (ie. II=-III)? This is consistent with aVF=(II+III)/2 =0 and aVL=(I -III)/2= (I+II)/2=-aVR.

Catheter ablation in rate-controlled atrial fibrillation with severely reduced ejection fraction: intervention for irregularity-mediated cardiomyopathy - Journal of Interventional Cardiac Electrophysi... Background Recent evidence suggests atrial fibrillation (AF) causes cardiomyopathy due to remodeling driven by both irregular rate and rhythm. Atrial fibrillation (AF) ablation in patients with reduce...

Increasingly compelling data for persistent AF/HFrEF pts to receive early rhythm control. Also RACE II rate control definitions may not be completely adequate. #CardioSky #EPeeps

SGLT2 inhibitors exert cardioprotective effects in heart failure but the role of ketone oxidation has been debated.

Goedeke et al. used sophisticated tracer experiments to evaluate the effects of SGLT inhibitors on cardiac metabolism in models: https://www.jci.org/articles/view/176708

You used to call me on my self-own

Any programmed stim attempts from LV?

Fantastic presentation from Mina Chung on the results of the TRIM-AF study.

RFM +/- Metformin had benefit in symptoms but no benefit on AF burden.

Left Atrial Appendage Closure after Ablation for Atrial Fibrillation | NEJM Oral anticoagulation is recommended after ablation for atrial fibrillation among patients at high risk for stroke. Left atrial appendage closure is a mechanical alternative to anticoagulation, but ...

Congratulations to @omwazni and the OPTION study team on the @ahascience.bsky.social presentation and publication of the OPTION trial.

Similar low rates of stroke post ablation (no difference with laao vs OAC) with no significant 23% lower rate of major bleeding.
