A kind of dynamic ecg monitoring instrumentTechnical field
The present invention relates to electrocardiogram monitoring Instrument technology field, and in particular to a kind of dynamic ecg monitoring instrument.
Background technology
Holter (DCG), clinic are also known as Holter electrocardiograms, can continuously record the full mistake of 24 hours electrocardio-activitiesEcg data under journey, including the different situations such as rest, activity, dining, work, study and sleep, it can be found that conventional ECGND arrhythmia cordis and myocardial ischemia, and it can be found that the latent dangerous factor of sudden death.Therefore, it is necessary to which one kind can fitThe monitoring instrument of long-time monitor ECG is answered with meet demand, at present, portable dynamic ecg monitoring instrument on the marketThe factor of following influence detection accuracy be present in device：1st, cause of failures：Patient when motion and rest due to disturbing, also magnetic field shadowRing dynamic ecg monitoring effect to make a big impact, patient can more or less contact some forceful electric power sources in hospital or outside of being inAnd magnetic field, it will also result in electrocardiographic wave distortion；Interference is excessive and influences diagnosis report mistake illusion.2nd, electrode slice contacts notIt is good, some patients with machine from institute after, may by it is casual drawing, perspire, get wet with it situations such as occur, be close to electricityPole releases or wire dropping, the part record missing of this period, even if patient can settle a dispute by the parties concerned themselves, electrode or wire is voluntarily pressedOn, if in the case where two or more electrode cable comes off, however not excluded that patient is even wrong electrode cable,（Such as LR leading with RRLine exchanges, V 1 with V 2 location swap etc.）Possibility, loose contact, with daylong machine, patient is not known, causes nothingRecord, without figure, also there is the roomy lopsided QRS of electrocardiogram and do not have a shape in some patients, but false VPB caused by disturbing,It is not real VPB, patient's self reason is perspired, and EGC pattern illusion can all occur in lead connection error.3、The influence of patients factors, position chanP can cause the skew of ST sections in electrocardiogram and the change of T ripples, or even the ST-Segment havingReachable 0.1-0.2Mv is offset, it is especially the most obvious in lower wall lead, particularly there are coronary disease and angina pectoris, the asymptomatic heart to suspectionFor the patient of myocardial ischemia, it can influence to diagnose, human factor causes to judge by accident during ambulatory ECG analysis, regards myocardial ischemia asSuspect the figures such as angina pectoris.4th, the influence of interfering material, advise patient's instrument to be afraid of moist, easily influenceed by the interference of various electromagnetic wavesIdentification result, it is desirable to patient protects instrument, in detection will away from the larger electrical equipment of electromagnetic field such as electromagnetic oven, micro-wave oven, electric blanket,The foeign element such as receive calls less also influences electrocardiographic diagnosis.
