Abstract

An apparatus including a main processing unit. The apparatus further including a precordial patch coupled to the main processing unit, the precordial patch having a plurality of sensors for detecting heart sounds and cardiac electrical signals (ECG). The apparatus further including a probe coupled to the main processing unit, the probe having a sensor for detecting oxygen saturation of blood circulating through a human. A method is further described including simultaneously measuring and analyzing heart sounds, cardiac electrical signals (ECG) and oxygen saturation of blood circulating through a human. The method further includes performing an algorithm to determine the presence of a significant congenital heart disease and displaying management recommendations based on results of the algorithm.

Claims

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.

2. The apparatus of claim 1, further comprising a plurality of leads coupled at one end to respective ones of the plurality of third sensors and bundled at another end, wherein the plurality of third sensors comprise sensors positioned according to a plurality of lead positions.

3. The apparatus of claim 1, further comprising a plurality of leads coupled at one end to respective ones of the plurality of third sensors and bundled at another end, wherein the plurality of third sensors comprise six sensors positioned corresponding to the lead positions of V₁, V₂, V₃, V₄, V₅, and V₆.

4. The apparatus of claim 1, wherein the patch further comprises at least one indicator for an anatomical landmark.

5. The apparatus of claim 1, wherein each of the plurality of second sensors is disposed at a different region of the precordial patch relative to each of the plurality of third sensors.
