Description
Technical field
This application involves ECG techniques fields, more particularly to a kind of electrocardiogram teaching appliance.
Background technique
For medical personnel, in some cases, when whether judging patient sb.'s sickness becomes critical, electrocardiogram and the heart
Particularly critical effect is played in electricity monitoring, and electrocardiogram of failing to understand even will cause the opportunity for losing and giving emergency treatment to a patient.Currently, electrocardiogram
And cardiac monitoring is widely used in clinical position.Electrocardiogram have become medicine, nursing etc. profession must learn content.
The key of electrocardiogram study is electrocardiogram principle.
In traditional teaching method, the big drawback of teaching presence two of electrocardiogram principle, first is that the teaching of electrocardiogram schematic diagram
It disconnects with cardiac anatomy, second is that showing three-dimensional electrocardio depolarization resultant vector with X-Y scheme.
The entire learning process of traditional electrocardiogram principle needs spatial thought conversion three times.It explains one by one below.
Firstly, understanding the concept of complex electrocardio vector ring.Heart wink when complex electrocardio vector ring is atrium or sequences of ventricular depolarization
When combination current dynamic change ring, be a three-dimensional vector.Fig. 1 is the common figure work for explaining complex electrocardio vector ring
Tool, wherein the curve of two-wire item indicates that complex electrocardio vector ring, the curve of the single line item in figure indicate complex electrocardio vector in figure
Projection of the ring in Different Plane.Wherein YOZ plane represents face amount, and the face XOZ represents horizontal plane (bottom surface in figure), XOY
Represent side.
Secondly, understanding complex electrocardio vector ring in the projection of Different Plane.Fig. 2 shows complex electrocardio vector ring in human body
The coordinate surface of face amount projection, coordinate are the mark common frontal plane lead coordinates of electrocardial vector.
Finally, the electrocardial vector size on horizontal plane and face amount different directions is projected to each lead measurement again.
During three above, first process is relatively difficult, i.e., how the shape of resultant vector ring generates,
Its concrete shape is difficult to describe.And if cannot understand complex electrocardio vector ring, which has no way of talking in face amount and horizontal plane projection
It rises, just it is even more impossible to understand subsequent each lead measurement for students.
The teaching of electrocardiogram principle at present mainly relies on the space diagram teaching or animation that plan view is drawn
Technology shows that heart removes the picture that electrode current is conducted along conduction path, the religion for the measurement electrocardial vector that not can be used specifically
Learn model.Teaching accordingly, with respect to electrocardiogram principle or telling about based on method with traditional complex electrocardio vector ring, without phase
Close teaching aid.

The structure of the electrocardiogram teaching appliance of the application is explained above, illustrates its application method below:
(1) after opening parallel light source, ventricle free surface and diaphragmatic surface can be mapped to face amount by cardiac module 10 and lead
Join coordinate and horizontal plane lead coordinate.
(2) according to the depolarization current direction in each face, can show each face of ventricle except electrode current be projected in it is each
Direction and size in lead.
(3) sequences of ventricular depolarization electric current sequentially in time, is divided into 3 parts, 102 depolarization of first part's interventricular septum, this part
Except electrode current only accounts for small part on the QRS wave of electrocardiogram, can ignore；Second part left and right ventricles free surface removes
Pole, Part III are left and right ventricles diaphragmatic surface depolarizations.The electrocardiogram teaching appliance of the application mainly measures second and Part III
Except electrode current.
(4) if depolarization current direction is consistent with lead axis direction, except electrode current is positive value；If depolarization current direction
It is contrary with axis of leads, then except electrode current is negative value；If depolarization current direction is vertical with lead axis direction, in the axis of leads
On do not measure then, be zero.If sequences of ventricular depolarization electric current is positive value on certain lead direction, the QRS wave of the lead shows as direction
Upwards, if sequences of ventricular depolarization electric current is negative value on certain lead direction, it is downward that the QRS wave of the lead shows as direction.
(5) according to ventricle free surface and diaphragmatic surface except electrode current is projected in the big of face amount and the direction sum of horizontal plane difference lead
Small (since the thickness of left ventricular wall is 3 times of right ventricular wall thickness, the depolarization vector size and right ventricle depolarization of left ventricle projection
It will be multiplied by 3), can directly judging the main wave direction of the QRS wave of electrocardiogram difference lead and size before vector comparison.Electrocardial vector
101 are just directly mapped with ECG pattern.
The electrocardiogram teaching appliance of the application has following advantage:
1) left and right ventricles free surface and diaphragmatic surface are projected to frontal plane lead coordinate and horizontal plane lead coordinate by the present invention respectively,
Left and right ventricles are defined first except the size of electrode current is determined by the structure of ventricle, remove electrode current in conjunction with certain part ventricle wall
Walking direction part ventricle wall depolarization electrocardial vector direction, in conjunction with left locular wall than right ventricle wall thickness, so that it may according to ventricle wall
Different piece projected size and depolarization current direction measure the part sequences of ventricular depolarization electric current different lead axial projections size and
Direction.It needs not move through multiple space and converts the big of the depolarization vector that can judge heart substantially in some lead direction
It is small.
2) present invention can demonstrate the principle that the heart depolarization vector of different leads generates using cardiac module, allow in turn
Student learns how the size of anatomical structure feature and the ECG pattern anti-position for treating others with sincerity dirty and chamber according to heart.The heart
The figure of electrograph and the anatomical structure of heart connect, and are abstracted electrocardiogram no longer hard to understand.
3) no matter how opposite anatomical position of the heart in thoracic cavity changes, and heart removes the conduction side of electrode current inside it
To substantially constant, each lead measurement direction of heart is also to be basically unchanged.So according to the present invention can be with the analogue measurement heart
The change for the electrocardial vector that different leads measure after dirty change in location, so as to speculate the change of its ECG-QRS Wave form.
Then it is compareed again with actual ECG-QRS Wave figure, keeps the study of electrocardiogram principle more intuitive, understandable, flexible.Student can
To draw inferences about other cases from one instance, electrocardiogram principle is thoroughly understood.
The foregoing is merely presently filed embodiments, are not intended to limit the scope of the patents of the application, all to utilize this
Equivalent structure or equivalent flow shift made by application specification and accompanying drawing content, it is relevant to be applied directly or indirectly in other
Technical field similarly includes in the scope of patent protection of the application.
