1. A garment to be worn directly on an upper body of a person, wherein the garment is formed from fabric and wherein the garment comprises a plurality of mounting points for electrocardiogram (ECG) electrodes to which ECG electrodes are configured to be releasably attached and a flexible printed circuit board,
wherein for each mounting point of the plurality of mounting points a wire is embedded in the fabric, each of the wires being configured for electrically connecting an ECG electrode attached to the respective mounting point to the flexible printed circuit board such that an electrical signal sensed by the respective ECG electrode is transmitted to the flexible printed circuit board via the wire,
wherein the flexible printed circuit board comprises processing circuitry configured for evaluating signals received via the wires from the ECG electrodes attached to the plurality of mounting points obtain results and configured for transmitting the results to an external receiver,
wherein the flexible printed circuit board comprises a substrate formed from a flexible polymer film on which the processing circuitry is arranged, wherein the flexible polymer film is a polyimide film, wherein the processing circuitry comprises electronics components soldered to the substrate and connected by copper tracks, and
wherein the substrate and the processing circuitry are encapsulated by an upper and a lower encapsulating film, wherein the upper and lower encapsulating films are formed from a polymer and the polymer is a polybutylenadipat-terephthalat;
wherein the fabric comprises an inner layer and an outer layer, wherein the plurality of mounting points for the ECG electrodes is arranged on the inner layer, wherein the inner layer is arranged at least partially between the outer layer and skin of the person wearing the garment and wherein the wires are embedded in the fabric in that the wires are arranged between the inner layer and the outer layer and knitted to the fabric, and further wherein the inner layer is formed from a non-elastic material and the outer layer is at least partially formed from elastic material.
