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.

Her Apple Watch suddenly told her that she is in atrial fibrillation. Patients with healthy AV nodes who are not on AV nodal blockers and who are not hyperkalemic should have a rapid ventricular response if they have paroxysmal Atrial fibrillation. I focus my comment on a few additional aspects regarding new AFib.

Such as atrial fibrillation or sinus rhythm with extrasystoles. Answer shown below: This can be even more challenging with atrial fibrillation where the only thing you can rely on is careful morphologic inspection. Sometimes this type of artifact happens in atrial fibrillation and it can be very challenging.

Note: Due to the limited number of normally conducted beats — it is hard to be sure whether the underlying rhythm is sinus with baseline artefact or atrial fibrillation. After resuscitation and defibrillation , there were no more episodes of TdP. Below is the patient’s 12 lead ECG following defibrillation.

It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. The rhythm is atrial fibrillation. 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 disorder is rare — but it takes on importance as a potential cause of atrial and ventricular arrhythmias, including cardiac arrest. Treatment is by ICD ( implantable cardioverter defibrillator ). Males with a QTc ≤330 ms — and females with a QTc ≤340 ms are defined as having SQTS , even if they are asymptomatic.
