16, 2025 Primary results from the DEFINE AFib clinical study show the Medtronic LINQ family of insertable cardiac monitors (ICM), paired with a novel algorithm, were able to detect atrial fibrillation episodes and properly risk stratify patients as high risk prior to an AF-related healthcare utilization 80% of the time.

MY Thoughts on Today’s CASE: As tempting as it might be to reach for the defibrillator on seeing the ECG shown in Figure-1 — My initial reaction was different. The April 6, 2023 post — excessive baseline artifact misdiagnosed as AFib ( instead of sinus rhythm with AV Wenckebach — as in Figure-4 in this post ). Is this VT?

We examined the effect of ibutilide, a class III antiarrhythmic agent, on the energy requirement for atrial defibrillation and assessed the value of this agent in facilitating cardioversion in patients with atrial fibrillation that is resistant to conventional transthoracic cardioversion. Methods. . =

But artifact is "alive and well" — and learning to recognize it will amaze many of your colleagues ( and may serve to avoid an unnecessary defibrillation or two ). The April 6, 2023 post — excessive baseline artifact misdiagnosed as AFib ( instead of sinus rhythm with AV Wenckebach — as in Figure-4 in this post ).

It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. I sent it to 2 of my ECG nerd colleagues with no clinical information whatsoever, who instantly said: "Looks like afib with subendocardial ischemia and right heart strain pattern." "I The rhythm is rapid AFib. CPR was initiated immediately.

After resuscitation and defibrillation , there were no more episodes of TdP. Below is the patient’s 12 lead ECG following defibrillation. Of note — the QT interval of beat #5 ( blue line ) is markedly prolonged compared to the QT interval in the beginning of the tracing ( red line ). What does this ECG tell you?

Treatment is by ICD ( implantable cardioverter defibrillator ). Assuming the patient did not have hypercalcemia and there was no history of cardiac arrest, unexplained syncope or AFib at an early age — cardiac risk from a “short” QTc is clearly less than for patients with frank SQTC.
