Boston Scientific Initiates AVANT GUARD Clinical Trial to Evaluate FARAPULSE Pulsed Field Ablation System as First-Line Treatment for Persistent Atrial Fibrillation

DAIC

The trial will evaluate the outcomes of therapy provided with the FARAPULSE PFA System versus AADs, including device-or procedure-related adverse events, the rates of freedom from AF, atrial flutter, or atrial tachycardia, as well as AF burden – a measurement of the amount of AF an individual experiences.

New Onset Heart Failure and Frequent Prolonged SVT. What is it? Management?

Dr. Smith's ECG Blog

There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm. There are clearly no flutter waves, so it is not atrial flutter (a "macro-reentrant" atrial tachycardia) Is it AVNRT originating at the superior pole of the AV node, resulting in a retrograde P-wave before the QRS?

Emergency Department Syncope Workup: After H and P, ECG is the Only Test Required for Every Patient.

Dr. Smith's ECG Blog

Electrophysiologic studies were performed in selected patients only as clinically appropriate. Arrhythmias as a cause of syncope were diagnosed by cardiac monitoring or electrophysiologic testing. Holter monitoring, or intracardiac electrophysiologic studies, alone or in combination (diagnostic yields, 5% to 35%). Circulation.
