Provided is a real-time multi-monitoring method using an electrocardiograph and a real-time multi-monitoring method using an electrocardiograph including connecting at least one of a plurality of electrocardiographs via a network; receiving identification information of a user which is linked to an electrocardiograph to identify the plurality of electrocardiographs; collecting biometric signal information from the plurality of electrocardiographs; and analyzing a health condition in consideration of predetermined reference information which is defined for each user and biometric signal information collected from each of the plurality of electrocardiographs.

A system includes a signal generator, configured to pass a generated signal, which has two different generated frequencies, through a circuit including an intrabody electrode. The system further includes a processor, configured to identify, while the generated signal is passed through the circuit, a derived frequency, which is derived from the generated frequencies, on the circuit, and to generate, in response to identifying the derived frequency, an output indicating a flaw in the electrode. Other embodiments are also described.

Provided is a method for displaying electrocardiogram (ECG) data for the detection of myocardial ischemia, wherein a map is configured in the form of concentric circles using ST segments obtained through ECG measurement such that the inner circle consists of a “depression” origin and the outer circle consists of an “elevation” origin so as to display by connecting graphs or dots according to the measured ECG values of limb leads (frontal plane leads; I to aVF) and chest leads (precordial plane leads; V1 to V6), and the intuitive confirmation of the presence of subendocardial ischemia or transmural injury is enabled through the map, thereby making it possible to quickly and accurately recognize the patient's conditions and inducing prompt treatment.
