Novel 12-lead system easy for computer electrocardiosignal feature recognition

Abstract

The invention discloses a novel 12-lead system easy for computer electrocardiosignal feature recognition. By adjusting the position of each electrode and changing the connection mode of forming 12 leads, the novel 12-lead system has the following advantages: the signal-to-noise ratio of main leads for arrhythmia analysis can be improved; each waveform of the electrocardiogram is related to a conventional electrocardiogram; the baseline drift of the electrocardio record is reduced; interference of myoelectricity, alternating current and the like is reduced, and automatic analysis of computer electrocardiosignals is facilitated.

Description

technical field [0001] The invention relates to the fields of biomedical engineering, medicine and medical equipment, in particular to a novel 12-lead system which is easy to identify the characteristics of computerized electrocardiographic signals. Background technique [0002] Conventional 12-lead resting electrocardiogram is the earliest and most widely used lead system. It has been used for nearly 100 years worldwide. Due to the existence of limb electrodes, its long-term monitoring or recording is limited, and it is far away from the heart power supply, which is extremely difficult. Susceptible to myoelectric interference; in 1966, Mason-Like innovated and improved the 12-lead system in order to meet the needs of exercise, monitoring and dynamic ECG recording. significantly lower, but because the electrode is placed on the edge of the deltoid muscle in the subclavian fossa, the electrode of the lower limbs is moved to the anterior axillary line, the midpoint between the...

[0002] Conventional 12-lead resting electrocardiogram is the earliest and most widely used lead system. It has been used for nearly 100 years worldwide. Due to the existence of limb electrodes, its long-term monitoring or recording is limited, and it is far away from the heart power supply, which is extremely difficult. Susceptible to myoelectric interference; in 1966, Mason-Like innovated and improved the 12-lead system in order to meet the needs of exercise, monitoring and dynamic ECG recording. significantly lower, but because the electrode is placed on the edge of the deltoid muscle in the subclavian fossa, the electrode of the lower limbs is moved to the anterior axillary line, the midpoint between the costal margin and the anterior superior iliac spine. Movement and breathing movement, muscle activity under the electrode, generate a large muscle current, directly increase the interference of the frontal lead ECG, and the current popular lead wires are independent, connected to the electrode button on the chest wall, and recorded for a long time In the process, the wires swing with different positions of the body, causing baseline drift, increased myoelectric interference, low signal-to-noise ratio, and even poor contact between the electrodes and the skin, resulting in no ECG records for the corresponding leads, and difficult computer signal recognition.
