Answer: VizD ECG Challenge Week of 4/30/2007

Despite many close entries, there was NO WINNER for this week's VizD.

Therefore, the pot doubles to $10

Match the ECG with the most likely clinical scenario...

(click on ECG to enlarge)




Clinical Scenario:

1. 59-year-old man with crushing substernal chest pain that radiates to left arm, associated with shortness of breath and diaphoresis

2. 4
5-year-old man with a long-standing history of hypertension presents with a finger laceration

77-year-old woman with known coronary disease and recent aortic valve replacement presents with ankle pain after a fall


ECG A = clinical scenario 2 (Left Ventricular Hypertrophy)

S wave in V1/V2 + R wave in V5/V6 > 35 mm
Any precordial lead > 45 mm
aVL (R wave) > 11 mm
I (R wave) > 12 mm
aVF (R wave) > 20 mm

ECG B = clinical scenario 3 (Left Bundle Branch Block)
QRS duration > 120 msec
Broad, monomorphic R waves in I and V6 with no Q waves, may have notching
Broad, monomorphic S waves in V1, may have small r wave

ECG C = clinical scenario 1 (Antero-septal STEMI)
ST elevation V1 – V3
ST elevation I, aVL
ST depression II, III, aVF

The next VizD will be posted on Monday May 7th

is a weekly contest of an interesting or pathognomonic image from emergency medicine. Its goal is to integrate learning into a fun and relaxed environment. All images are original and are posted with the consent of the patient. For more information please refer to the following link.
