Do I need to shave my chest before an echocardiogram?
You can be asked to shave if your chest is quite hairy
Thanks for using the Ask a Doctor service.
The answer to this question depends on how hairy your chest is. An electrolyte gel is applied between the transducer and the skin of your chest while performing an echocardiogram. If you have more hair on your chest, they impede the signals between the transducer and the chest and therefore you might be advised to shave your chest.
