1. A waterproof modular electrocardiogram (ECG) electrode assembly for use in a wearable cardiac monitoring device, the assembly comprising:
a main circuit board comprising active ECG processing circuitry encapsulated in a main circuit waterproof moldable dielectric polymer; and
an ECG electrode mechanically coupled to the main circuit waterproof moldable dielectric polymer, the ECG electrode configured to be electrically coupled to a portion of the main circuit board;
wherein the ECG electrode is removably coupled to the main circuit waterproof moldable dielectric polymer with an adhesive; and
wherein an insulating material layer is disposed between the ECG electrode and the main circuit waterproof moldable dielectric polymer.
