Lead aVR: The Forgotten 12th Lead

avr

Augmented leads (aVR, aVF, and aVL) were developed to derive more localized information looking at the right, lower, and left part of the heart respectively.  Specifically, lead aVR obtains information from the right upper side of the heart.  It also gives reciprocal information on the left lateral side of the heart, which is already covered by leads aVL, I, II, V5, and V6.  This is the main reason lead aVR has become forgotten.

RUSH protocol: Rapid Ultrasound for Shock and Hypotension

Patients with hypotension or shock have high mortality rates, and traditional physical exam techniques can be misleading. Diagnosis and initial care must be accurate and prompt to optimize patient care. Ultrasound is ideal for the evaluation of critically ill patients in shock, and ACEP guidelines now delineate a new category of ultrasound (US)– “resuscitative.” Bedside US allows for direct visualization of pathology and differentiation of shock states.

The RUSH Protocol was first introduced in 2006 by Weingart SD et al, and later published in 2009. It was designed to be a rapid and easy to perform US protocol (<2 minutes) by most emergency physicians.

How do you perform the RUSH protocol?
