Early treatment of persistent AF can reduce the risk of blood clots, stroke, and heart failure, and may prevent the disease from becoming permanent. Patients are often treated with AADs as frontline therapy for heart rhythm maintenance, though some can experience adverse effects and limited efficacy.

This strip was obtained: Apparent Wide Complex Tachycardia at a rate of 280 What do you think? He cardioverted to sinus rhythm, and a 12-lead was obtained. Troponins 34>33>43, likely secondary to myocardial injury from tachycardia. Determining heart rate is easy when the rate is not overly fast.

Our mission to combat complex heart rhythm diseases relies on optimizing interoperability. The Volta AF Xplorer is a digital AI companion designed to assist cardiologists with real-time identification of specific abnormal electrograms (EGMs) known as spatio-temporal dispersed EGMs during AF and atrial tachycardia procedures.
