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.
