This is an EKG tattoo sent back to me after a consulting email:
This tattoo is of a very simple and elegant EKG showing one sinus heartbeat. All waves look appropriately sized and are aesthetically pleasing.
Tips: The QRS (the sideways Z shaped wave in the middle of the tattoo) must be kept as narrow as possible to avoid giving the appearance of a damaged heart muscle. I am told this can be difficult to accomplish without the ink running. Make sure you have a conversation with your artist about keeping the QRS complex as narrow as possible.
