Which are the electrocardiogram characteristic of the block of sinus room? 's symptom
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.
2The electrocardiogram characteristic of the block of one degree of sinuses room:
2The degree type block of sinus room:
One is shortened gradually among A P-P, one among long P-P appears finally, shortened gradually hereafter, went round and began again.
B One is smaller than sum of one between two basic P-Ps among long P-P.
C The issue is longer than one among its former P-P among first P-P after one among long P-P.
D The above three are typical Wen's phenomenon. What see is mostly atypism ~s on clinic. Can be shown as: One was shortened gradually among P-P, but P-P did not continue shortening before P wave is left out, namely did not become or lengthen slightly, then one among long P-P just appears. Among P-P issue gradually shorten,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 Conduct 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.
The block electrocardiogram characteristic of one degree of sinuses 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. Have room the intersection of ease and fight and room the intersection of ease and person who fight rhythm of the heart contribute to the intersection of sinus and the intersection of room and diagnosis of block. Excited in the room when the sinus stops fighting and is more often a bit inhibited at the same time.
