Description
Technical field
The utility model belongs to medical teaching apparatus, relates in particular to the oesophagus intubate teaching aid for practising Esophageal electrophysiological examination.
Background technology
Surface electrocardiogram is the goldstandard of diagnose arrhythmia, and one over 100 years for clinical diagnosis and treatment provides in time, accurate, reliable diagnosis basis. But while needing patient to show effect due to arrhythmia cordis, just can trace, and measuring point is confined to body surface, causes P ripple unclear, therefore cannot specify the exciting order of ARR concrete originating point or heart, can not correctly diagnose for some complicated arrhythmia cordis.
Oesophagus and heart are all positioned at mediastinum, and heart is front, and oesophagus, rear, only has pericardium to be separated by between the two. The antetheca of LEP and heart rear wall are closely adjacent, and to next, near left ventricle, wherein behind atrium sinistrum, outside major part is close to oesophagus antetheca. In the time that atrium mapping is carried out in intracardiac electrophysiology inspection, find that the P ripple that in the exciting ripple of the atrium sinistrum electricity that side is recorded to and oesophagus, respective horizontal is recorded to is the most approaching at home and abroad, illustrate that the tall and big P ripple being recorded in oesophagus is caused by atrium sinistrum is exciting.
Esophageal electrophysiological examination is a kind of non-invasive clinical electric physiology diagnosis and treatment technology, according to oesophagus and anatomical cardiac feature in close relations, oesophagus is sent into in special esophageal electrode conduit via intranasal application or oral cavity, utilize to be placed on the electrode that is equivalent to atrium sinistrum level in oesophagus and indirectly heart to be carried out to electrophysiologic study. Synchronous recording body surface leads and can make analysis to the electrophysiological characteristics of heart and arrhythmogenic mechanism with esophageal lead electrocardiogram; obtain the electric-physiology parameter at the each position of heart; can disclose its mechanism by bringing out, stop arrhythmia cordis, provide scientific basis for correctly diagnosing and treating various arrhythmia cordis.
Esophageal electrophysiological examination electrode catheter localization method is as follows: in the time that electrode catheter enters 35-40cm or arrive by patient's height measure formula calculating [(person under inspection height+200) ÷ 10] cm, electrode is substantially positioned at and is equivalent to atrium sinistrum level.
Concrete grammar is positioned with:
1) empirical method (according to height location): the male sex: 35-40 (37cm); Women: 33-37 (35cm).
2) ear sword is apart from method: the ear sword spacing (ear-lobe is to the distance of xiphoid-process) that catheter depth is patient adds 8cm.
3) position according to esophageal electrocardiogram: according to catheter electrode degree of depth difference in oesophagus, conventionally can be recorded to the esophageal lead electrocardiogram waveform of four kinds of different shapes, change the most obvious with P ripple. P ripple be positive and negative two-way or upright be optimum position when tall and big.
1. atrium upper area: when electrode is positioned at oesophagus and is equivalent to top, atrium sinistrum, when atrium is exciting, P vector deviates from electrode, and P ripple is taking negative wave as main, and QRS ripple is Qr type. In the time that electrode is divided a word with a hyphen at the end of a line downwards gradually, P ripple negative wave reduces gradually, and forward wave increases gradually;
2. atrium central region: electrode is positioned at oesophagus and is equivalent to atrium sinistrum when middle part, and P vector first, in the face of electrode, then deviates from electrode, forms sharp-pointed positive and negative diphasic P wave, and QRS ripple is still Qr type;
3. atrium lower area: when electrode is positioned at oesophagus and is equivalent to bottom, atrium sinistrum or coronary sulcus position, P vector, all in the face of electrode, forms tall and big sharp-pointed forward P ripple, the very little or disappearance of negative wave. QRS ripple is QR type or qR type;
4. ventricle upper area: electrode is positioned at oesophagus and is equivalent to left ventricle upper area, P ripple forward circle is blunt, and amplitude reduces. QRS ripple is qR type or R type;
But no matter which kind of method, in concrete oesophagus intubate operating process, all requires medical worker to possess consummate technology and could exactly esophageal electrode conduit be inserted to oesophagus, avoids bringing discomfort or injury to patient.
