Abstract
The invention discloses a cardiac electric axis and clockwise transposition measuring tray which comprises a measuring tray main body, wherein a frontal plane six-axis system is arranged on the front surface of the measuring tray main body and comprises six limb leads; a rotatable indicator for measuring the cardiac electric axis is arranged in the middle of the measuring tray main body; a clockwise transposition pattern is arranged on the back surface of the measuring tray main body and comprises sixteen chest leads surrounding the heart; and marks are arranged among the six limb leads. The cardiac electric axis and clockwise transposition measuring tray has the advantages that two types of contents are skillfully combined together, the twenty-two leads clinically used are shown in a mould, and the frontal plane, the horizontal plane and the leads are also shown, which assists students in better understanding and mastering the electrocardiology principle in the learning process of electrocardio basic knowledge.
Description
Technical field
The present invention relates to a kind of cardiac electric axis and clockwise transposition measurement dish.
Background technology
Conventional mean electrical axis measures two kinds of methods: amplitude of vibration method and ocular estimate.Amplitude of vibration method determines cardiac electric axis by calculating the I and III QRS burst amplitude led, and this method is measured accurately, but comparatively bothers.Ocular estimate adopts electrocardiogram I and aVF leads or I and III leads to judge cardiac electric axis, and method is easy, but the concrete number of degrees not easily judge.
Summary of the invention
In order to overcome the shortcomings such as the complicated and concrete number of degrees of the measuring method that exists in existing cardiac electric axis measuring method not easily judge, the invention provides that a kind of amplitude of vibration method and ocular estimate combine, measure fast and accurately, mechanism easy to understand, method are easy to the cardiac electric axis grasped and clockwise transposition measurement dish.
The technical solution used in the present invention is:
Cardiac electric axis and clockwise transposition measurement dish, is characterized in that: comprise measurement disc main body, described measurement disc main body front is provided with face amount hexaxial reference system, and described face amount hexaxial reference system is made up of six limb leads; Centre is provided with the rotary pointer measured for cardiac electric axis; The back side is provided with clockwise transposition pattern, and described clockwise transposition pattern is made up of 16 chest leads round heart.
Further, scale is provided with between described six limb leads.
Technical conceive of the present invention is:
1, according to electrocardial vector principle, QRS wave-amplitude the highest or the darkest leading in six limb leads, namely cardiac electric axis leads near this, now turns to this to lead on pointer; To find out in six limb leads high or dark the leading of amplitude second again, slightly near amplitude the highest or the darkest leading between namely cardiac electric axis leads at these two, namely pointer is forwarded to this place is the cardiac electric axis number of degrees.
2, the clockwise transposition of heart judges according to the change of precordial lead electrocardiogram waveform, is RS type without the QRS ripple that leads of V3 during clockwise transposition.Clockwise rotation is that V4 or V5 or V6 lead in RS type; Counterclockwise rotation is that V1 or V2 leads in RS type.This content indigestion on plane graph, the situation of different QRS waveform change of leading when measurement dish enables student intuitively arrive heart generation clockwise transposition.
Beneficial effect of the present invention is embodied in: have employed the measuring method that amplitude of vibration method and ocular estimate combine, use whole six limb leads, makes measurement fast and accurately; Make measurement cardiac electric axis mechanism easy to understand, method be easy to grasp.

Detailed description of the invention
Embodiment 1
Referring to figs. 1 through Fig. 2, cardiac electric axis and clockwise transposition measurement dish, comprise measurement disc main body, and described measurement disc main body front is provided with face amount hexaxial reference system, and described face amount hexaxial reference system is made up of six limb leads; Centre is provided with the rotary pointer measured for cardiac electric axis; The back side is provided with clockwise transposition pattern, and described clockwise transposition pattern is made up of 16 chest leads round heart.
Further, scale is provided with between described six limb leads.
Technical conceive of the present invention is:
1, according to electrocardial vector principle, QRS wave-amplitude the highest or the darkest leading in six limb leads, namely cardiac electric axis leads near this, now turns to this to lead on pointer; To find out in six limb leads high or dark the leading of amplitude second again, slightly near amplitude the highest or the darkest leading between namely cardiac electric axis leads at these two, namely pointer is forwarded to this place is the cardiac electric axis number of degrees.
2, the clockwise transposition of heart judges according to the change of precordial lead electrocardiogram waveform, is RS type without the QRS ripple that leads of V3 during clockwise transposition.Clockwise rotation is that V4 or V5 or V6 lead in RS type; Counterclockwise rotation is that V1 or V2 leads in RS type.This content indigestion on plane graph, the situation of different QRS waveform change of leading when measurement dish enables student intuitively arrive heart generation clockwise transposition.
Embodiment 2
With reference to figure 3, coiled by measurement and judge cardiac electric axis.Can see QRS burst amplitude maximum be II to lead, so turn to II to lead on pointer, what QRS burst amplitude was second largest is I leads, so cardiac electric axis is led I and II to lead centre, II amplitude that leads is the highest, pointer to lead the corresponding number of degrees so should be partial to II, namely at about 50 °, according to knowledge, cardiac electric axis to be 50 ° be normal ECG (0 ° ~+90 °---normal, + 90 ° ~+180 °---right avertence---right ventricular hypertrophies, 0 ° ~-90 °---left avertence---left anterior hemiblock ,-90 ° ~-180 °---ultra-Right inclined).
With reference to figure 4, judge clockwise transposition.The figure figure that measurement dish V3 is right just that V5 is right, so we forward V5 position to the V3 figure in measurement dish, V5 is forwarded to like this from V3, namely turn to clockwise, just there occurs clockwise rotation, tentatively infer disease (clockwise rotation: chronic lung disease, right ventricular hypertrophy, counterclockwise rotation: left ventricular hypertrophy) simultaneously.
Content described in this description embodiment is only enumerating the way of realization of inventive concept; should not being regarded as of protection scope of the present invention is only limitted to the concrete form that embodiment is stated, protection scope of the present invention also and conceive the equivalent technologies means that can expect according to the present invention in those skilled in the art.
