Electrocardiogram analyzer


An electrocardiogram analyzer has a measurement section for measuring an electrocardiographic signal; a determination unit for determining, from arrhythmia determination reference information that is information pertinent to arrhythmia, whether or not an electrocardiogram multiplex, which includes a first predetermined number of heart beats, in the thus-measured electrocardiographic signal is arrhythmia; a reference waveform determination unit that determines a reference waveform from the electrocardiogram complex including the first predetermined number of heart beats when the determination unit has determined that the electrocardiogram complex is not arrhythmia, storing the thus determined reference waveform; and an analysis unit that performs an analysis as to whether or not an electrocardiogram complex being measured is arrhythmia by use of the stored reference waveform.. .

System and providing diagnosis and personalized abnormalities alerts and for providing adaptive responses in clinical trials


A personalized real-time automated cardiovascular monitoring system monitors abnormalities in a patient's cardiovascular activity data through the use of individually adjusted electrocardiogram holter apparatus (holter/ecg device) that provides an automatic medical diagnosis of cardiac abnormalities and generates abnormality alert signals representative of certain abnormalities in patient's cardiac activities. The signals are transmitted using a wireless network through a bi-directional wireless protocol.

Method and identifying cardiac risk


A cardiac-based metric is computed based upon characteristics of a subject's cardiac function. In accordance with one or more embodiments, the end of a mechanical systole is identified for each of a plurality of cardiac cycles of a subject, based upon an acoustical vibration associated with closure of an aortic valve during the cardiac cycle.

Electrode structure for measuring bio-signal and measuring electrocardiogram using the same


The electrode structure for measuring a bio-signal and an apparatus for measuring an electrocardiogram using the same are disclosed. The electrode structure for measuring a bio-signal, comprises an electrode pad to measure bio-signals based on capacitive coupling between the electrode pad and human skin; an absorption layer formed at one side of the electrode pad; and a preamplifier which is electrically connected with the electrode pad and filters noise from the bio-signals from the electrode pad and amplifies and outputs the signals.
