The invention provides an electrocardiogram monitoring garment. The electrocardiogram monitoring garment comprises a first electrocardiogram collecting
electrode, a second electrocardiogram collecting
electrode, a third electrocardiogram collecting
electrode and a first electrocardiogram
signal collecting base, wherein the first electrocardiogram collecting electrode serves as a differential
signal electrode and is arranged at the position, corresponding to the heart of the
human body, of the inner side of the monitoring garment; the second electrocardiogram collecting electrode serves as another differential
signal electrode and is arranged at the position, corresponding to the heart of the
human body, of the inner side of the monitoring garment; the third electrocardiogram collecting electrode serves as a
reference electrode and is arranged at the position, located below the second electrode, of the inner side of the monitoring garment; and the first electrocardiogram signal collecting base is arranged at the position, different from the first electrocardiogram collecting electrode, the second electrocardiogram collecting electrode and the third electrocardiogram collecting electrode, of the outer side of the monitoring garment and comprises three electrode buckles, and the three electrode buckles are correspondingly connected with the first electrocardiogram collecting electrode, the second electrocardiogram collecting electrode and the third electrocardiogram collecting electrode through wires embedded in the monitoring garment in an insulated mode respectively so that electrocardiogram signals obtained from the first electrocardiogram collecting electrode, the second electrocardiogram collecting electrode and the third electrocardiogram collecting electrode can be transmitted to a first electrocardiogram signal collecting box buckled on the first electrocardiogram signal collecting base.
