Classification and electrocardiogram characteristic _ general knowledge of the block of sinus room
The classification of the block of sinus room is: Degree, 2 degree and degree, the former two are also called incompleteness, the latter is also called completely. 2Degrees of sinus be blocked room based on different figures can divide for type and 2.
( 1) The electrocardiogram characteristic blocked in one degree of sinuses room: Ite down to copy the writing device, the block of one degree of sinuses room exists, but because the present electrocardiogram still can't form the electric potential on the small sinus room to write down to copy the writing device, so, it is unable to diagnose to have block of one degree of sinuses room simply in the body surface electrocardiogram.
( 2) 2The electrocardiogram characteristic of the block of one degree of sinuses room:
2Spend ' Wen type) The block of sinus room:
One is shortened gradually among P-P, one among long P-P appears finally, shortened gradually hereafter, went round and began again.
One is smaller than sum of one between two basic P-Ps among long P-P.
The issue is longer than one among its former P-P among first P-P after one among long P-P.
The above three are typical Wen's phenomenon. What see is mostly atypism ~s on clinic. Can be shown as: ( a) One is shortened gradually among P-P, but before (before namely long P-P) P wave is left out P-P does not continue shortening, namely does not become or lengthen slightly, then one among long P-P just appears. ( b) Among P-P issue shorten gradually,but it is long P-P might not a less than two sum of P-Ps. The reason to cause not typical Wen's phenomenon has sinus nature arrhythmic and shrinking etc. before one.
2The block electrocardiogram characteristic of sinus room of the degree of Model 2:
A Conduct the proportion rule: Can present 3: 2 ; 4: 3; 5: 4 grades conduct the proportion, and maitain unchanged. Can also present 2: 1 or 3: An intensity is blocked higher. As block than up to 3: 1 - 5: At 1 o'clock, can be called the block of rooms of high sinus. Ventricle rate is extremely slow at this moment.
B conducts proportion abnormality: Interim among a series of regular sinus P-P, one among long P-P of one P-QRS-T appeared suddenly, one is just the integer multiple of one among short P-P here. But the intermittence presents or exists time longer.
Degree is (complete) The block electrocardiogram characteristic of sinus room:
When the excitement of the sinus room knot all can't conduct and reach the atrium, sinus P wave totally disappears on the electrocardiogram, it is distinguished so unable to stop fighting with the continuation sinus. But if there is diagnosis that room ease fighting and room fighting rhythm of the heart of ease contributes to the block of sinus room. Excited in the room when the sinus stops fighting and is more often a bit inhibited at the same time.
