September is National Atrial Fibrillation (AFib) Awareness Month, a time dedicated to raising awareness about one of the most common yet often misunderstood heart conditions. Physicians have a crucial role in recognizing, diagnosing, and managing AFib to prevent its potentially life-threatening complications.

Cardioversion can be done pharmacologically (usually procainamide) , but why would you want to do that? Since the ventricular response in ECG #2 is comparable to the rate range for any patient who develops new-onset AFib — definitive diagnosis of WPW was not made in today's case until the 3rd ECG was obtained.
The study will compare the safety and efficacy of the Laminar LAAX System to commercially available left atrial appendage (LAA) closure devices, providing a potential non-pharmacologic alternative for eligible patients. This is particularly important for the nearly 40% of AFib patients who cannot tolerate long-term blood thinners3,4.
Hence, the IV Amiodarone was once one of the 2nd-line choices for acute pharmacologic cardioversion in such patients without hemodynamic instability. KEY Point: Nothing other than AFib with WPW results in a ventricular response this fast ( which is why Figure-2 is pathognomonic for AFib in a patient with WPW ).
She was known to have a history of poorly controlled COPD, AFib, and multivessel coronary disease. Pharmacology Review Digoxin is probably one of those medications vaguely recalled from paramedic school. Echocardiogram showed LVEF 55%, indeterminate diastole (due to AFib), and no significant valve pathology.
Among the fast Supraventricular Rhythms: This is not AFib — because the rhythm is regular. P utting I t A ll T ogether : — The Rhythm in Figure-1 What we have just described is the following: A regular WCT ( = W ide- C omplex T achycardia ) at a rate very close to 300/minute — without clear sign of atrial activity.
We discussed several pharmacologic and electrical options. In the best case scenario, all ST segment deviations may cease after a few minutes of normal heart rate, making Occlusion MI less likely. Conversely, if there truly is OMI underlying the rhythm, normalization of the rhythm will expedite its discovery and management.
