Automatic detection and transformation method for loose of electrocardiograph limb electrodes

Abstract

The invention discloses an automatic detection and transformation method for loose of electrocardiograph limb electrodes. When one limb electrode or two limb electrodes loose (s), the loosed electrodes need not to be fixed again; the electric potential at a Wilson center end can be automatically adjusted by a system, and an obtained precordial lead electrocardiogram is still normal, so that under the condition, most parts of recorded electrocardiogram lead signals are ensured to be still available. The automatic detection and transformation method for loose of the electrocardiograph limb electrodes has the characteristic that the signals are recorded stably in a long time process; and through automatic adjustment on the electric potential of the Wilson center, the most parts of recorded electrocardiogram lead signals are ensured to be stable and effective in a long-time recording process under the condition that parts of limb electrodes loose, thereby laying a good foundation for subsequent electrocardiogram analysis and processing.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to an automatic detection and conversion method for the fall-off of an electrocardiographic limb electrode in the process of electrocardiographic recording. Background technique [0002] The Holter system is used to record and analyze the ECG of patients in normal life. With the rapid development of electronic technology and storage technology, the Holter recorder has developed from continuously recording the ECG of 2-3 leads of the patient for 24 hours to continuously recording the patient's 12 During the electrocardiogram of 24 to 72 hours of lead, due to human body movement and electrode viscosity reduction during the electrocardiogram recording process, some electrodes often fall off, resulting in a significant decrease in the quality of the recorded electrocardiogram signal.

[0002] The Holter system is used to record and analyze the ECG of patients in normal life. With the rapid development of electronic technology and storage technology, the Holter recorder has developed from continuously recording the ECG of 2-3 leads of the patient for 24 hours to continuously recording the patient's 12 During the electrocardiogram of 24 to 72 hours, due to the human body movement and the decrease of electrode viscosity during the electrocardiogram recording process, some electrodes often fall off, resulting in a significant decrease in the quality of the recorded electrocardiogram signal

Especially in the 12-lead recording mode, the 6 chest leads use the Wilson central potential formed by the limb electrodes as the reference signal. If any limb electrode falls off and causes the Wilson center terminal potential to shift, it will cause the 6 chest leads to record fail

At present, most Holter systems use the alarm mode. When the electrodes fall off, the system will prompt the patient to put on the fallen electrodes again, but this seriously affects the daily life of the patients.
