EKGmachineA standard 12-lead EKG can be very telling for patients with chest pain or shortness of breath. A right ventricular (RV) and posterior wall infarct, however, can present very subtly. You can obtain special right-sided (V1R-V6R) and posterior leads (V7-V9), if you are concerned.

What are the indications for obtaining right-sided and posterior EKG leads?

Go to the ALiEM Cards site for more resources.

Addendum 3/11/11:
Right sided EKG leads (V1R-V6R) are positioned in a mirror image fashion from the standard 12-lead precordial leads.
Posterior EKG leads (V7-V9) are applied by moving V4-V6 in the posterior positions.
