Placing SmartHeart® on the Body

Correctly placing SmartHeart on the body can be done in a few simple steps.

Prep the Skin

Using tap water, dampen the areas of the body that come in contact with the electrodes. Ensure this step is done on the inner parts of the left and right arm, left waist area, and chest (under the center housing and along the belt where the built-in electrodes are located).

Identify Belt Size

Drawing an imaginary line between the middle of the left underarm and the left hipbone indicates the chest size. Enter the belt size into SmartHeart Pro mobile application.

Position SmartHeart®

Place SmartHeart against the center of the chest. On men, the device should be ½ an inch below each nipple. Women should place the SmartHeart under the breasts, as high up as possible. Tighten the belt, positioning the electrodes on moistened areas.

Position Electrodes

Position the square electrode at the belt line against the patient’s bare skin, halfway between your navel and left hip where water was applied. Position the triangular electrode in the left armpit and the round electrode in the right armpit. Lower each arm to hold the electrodes in place.

Performing an ECG

Once the SmartHeart® has been correctly placed on the body, you are ready to perform an ECG.
