Provided is an electrocardiogram lead guide system. The electrocardiogram lead guide system may include: an electrocardiograph attached to a part of a body of a patient and acquiring posture information and electrocardiogram signals using a plurality of sensors; and a user terminal providing guide information for guiding the attachment direction of the electrocardiograph based on the posture information.

The present invention relates to methods for marking positions for or for positioning of six ECG chest electrodes based on a subjects body height, which allows a reproducible placement of the electrodes in serial independent ECG measurements. The present invention further relates to a device for placement of ECG electrodes which implements said method, and methods and uses applying said device. Hence, the present invention provides an accurate and reproducible, easy to use and low-cost method and device for ECG chest electrode positioning, especially in serial examinations and in obese subjects by minimizing the mistakes in ECG chest electrode placement depending on the subjective and inaccurate defining of anatomic remarks for electrode positions.

To provide an electrocardiographic measurement apparatus that can prevent a variety of subjects from having discomfort when the apparatus is attached to the subjects. The electrocardiographic measurement apparatus includes: a plurality of electrodes that has a length along a circumferential direction of an upper arm, the length being variable in accordance with a length in the circumferential direction of the upper arm, and detects an electric potential from the upper arm that is brought into contact with the electrodes; and a device body that generates electrocardiographic information based on the electric potential detected by the plurality of electrodes.

Embodiments of the present disclosure relate to determining an optimal location on the body of a person where heart sounds may be optimally heard. The optimal location may be determined at a time prior to the attempted auscultation and ECG data corresponding to the optimal location may be stored in a memory of an auscultation device. Subsequently, when a e.g., physician wishes to listen to the heart sounds of the person, the physician may place the auscultation device at a first location on the patient. The auscultation device may periodically perform an ECG at a current location and use the ECG data at the current location and the ECG data at the optimal location to determine and provide guidance to the physician regarding a direction in which the auscultation device should be moved in order to reach the optimal location.
