1. An apparatus configured for detecting congenital heart disease based on a triple screen, the apparatus comprising: a sticker suitable for securing a precordial patch to a newborn human subject; a precordial patch separate from the sticker, the precordial patch comprising dimensions for positioning the precordial patch within a precordium of a newborn human subject; a plurality of first sensors associated with the precordial patch, a given first sensor being configured to facilitate detecting oxygen saturation based on pulse oximetry; a plurality of second sensors disposed at the precordial patch, a given second sensor being configured to facilitate one or both of (1) detecting heart murmur based on a phonocardiogram or (2) detecting cyanotic heart defect based on an echocardiogram; a plurality of third sensors disposed at the precordial patch, a given third sensor being configured to facilitate detecting abnormal electrical activity of a heart based on an electrocardiogram; and one or more processing units configured to determine a presence of congenital heart disease based on all three of (1) a detected oxygen saturation, (2) a presence or absence of a detected heart murmur and/or a detected cyanotic heart defect, and (3) a presence or absence of detected abnormal electrical activity of a heart.
