Figure Legend:
- ECG 1: Initial ECG obtained on presentation to the hospital
demonstrating disorganized activity.
ECG 2: Post defibrillation ECG demonstrating normal sinus rhythm.
- Image 1: Pulsed-Wave doppler of mitral inflow shows rhythmic
ventricular filling.
Image 2: M-mode of the mitral valve leaflets reveals rhythmic opening
and closing of valve leaflets.
- Clip 1: An apical 4-chamber view with perflutren lipid
microsphere contrast shows organized contractility despite ventricular
fibrillation.
- Clip 2: A parasternal long image without contrast similarly reveals
organized contractility.
