Embodiment 1

[0020] Develop a 12-lead Holter system, the recorder amplifies the ECG signal by 200 times. During the recording process, the lead signals V5, V1, II, and III are detected in real time. If the amplitude of the lead signals V5 and V1 exceeds 1000mV within 5s and the accumulative time exceeds 2.5s, the limb electrodes will fall off. Automatic detection and conversion. At this time, when the state combination of lead signals V5, V1, II, and III is state 1, isolate electrode R, and automatically adjust electrodes L and F to form the Wilson center terminal. If lead signals V5, V1 recover within 10s after adjustment If it is normal, the adjustment is successful; when it is in state 2, isolate the electrode L, and automatically adjust the electrodes R and F to form the center terminal of Wilson. If the lead signal V5 and V1 return to normal within 10s after adjustment, the adjustment is successful; When it is state 3, first isolate the electrode F, and automatically adjust electrode...

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. Especially in the 12-lead recording mode, the 6 chest leads use the Wilson centr...
