Methods and systems for electrode placement

A method for guiding placement of electrocardiogram (ECG) electrodes, the method comprising:

• normalizing a picture of a patient's chest using a normalization marker on the patient in picture;
• comparing the normalized picture of the patient to an electrode placement database to determine positioning of electrodes on the patient, wherein the electrode placement database comprises representations of a plurality of body types and predetermined conventional ECG electrode placement positions corresponding to each body type;
• and
• presenting an image of the patient showing positions for conventional ECG electrode positions on the image of the patient.

A method for determining the placement of ECG electrodes using a smartphone, the method comprising:

• taking a picture of a patient's chest including a normalization marker on the patient with the smartphone;
• normalizing the scale of the picture using the normalization marker;
• comparing the normalized picture to an electrode placement database comprising representations of a plurality of body types and predetermined ECG electrode placement positions for each body type to determine positioning of electrodes on the patient, wherein the scale of the normalized picture is the same as the scale of the electrode placement database;
• and
• presenting an image of the patient showing positions for ECG electrodes on the image of the patient.
