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.

Written by Pendell Meyers A man in his 70s presented with history of pacemaker presented with shortness of breath with exertion and presyncope. The ECG shows pacemaker failure with inability to capture or sense, with either underlying atrial fibrillation or junctional escape rhythm. large boxes ).

PMH: Known paroxysmal Atrial fib. He is usually is in sinus rhythm as far as he knows, but he cannot subjectively feel atrial fibrillation, so he is never completely certain when he is in sinus or atrial fib. Here is his ECG: Atrial Fib with a Ventricular Response of about 66. He immediately completely recovered.

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.

Written by Willy Frick A woman in her 90s with a history of end stage renal disease and complete heart block status post dual chamber pacemaker presented from home with acute onset dyspnea. In this case, it is atrial fibrillation. As per Dr. Frick — pacemaker spikes are best seen in lead aVL of ECG #1. ECG is shown below.

Here is the computer interpretation: ATRIAL FIBRILLATION WITH RAPID VENTRICULAR RESPONSE WITH ABERRANT CONDUCTION OR VENTRICULAR PREMATURE COMPLEXES LEFT AXIS DEVIATION [QRS AXIS beyone -30] NONSPECIFIC ST and T-WAVE ABNORMALITY The over-reading physician confirmed this diagnosis, which is incorrect. It is not atrial fibrillation.

Interpreting the waves and detecting abnormalities: Typically, the heart conducts electricity in a pathway starting in the sinoatrial node (SA), our heart’s “natural pacemaker”, located in the wall of the right atrium. AFIB/AFL – atrial fibrillation or atrial flutter episodes.
