Why can the heart beat? Blood of the pump when the heart is jumpy is carried to the whole body, once stop to beat, whole body machine can stop accordingly, is that what lets a heart keep beating? There are a few cells to be able to generate biology report activity in the heart, cause and control cardiac muscle systole, those who let a heart maintaining the pattern is jumpy. A kind of disease calls a heart to conduct block sluggish, be why the heart can be beaten by too acuteness work commonly?

Let a heart possibly stop fight, endanger life.
Pacemaker: Contain an imperfection help god implement
American Geleitebaji invented embedded type artificial pacemaker, the heart that can help a heart conduct block sluggish patient to return to normal beats. Pacemaker can monitor section law of the heartbeat, when the heart leakage jumps or had beaten slow when, can give out correctional electric pulse. Nowadays, have 100 thousand patients every year about embedded pacemaker. Although develop up to now, the medical treatment equipment of this kind of embedded sex is quite reliable, but still put in proper corrupt practice, for example the battery life of general pacemaker has 7 years only, need to replace, heart happening lets affect likely when replacing, additional, the circuitry of pacemaker is possible also damaged, to the heart the organization causes harm. embedded the patient of pacemaker still cannot accept MRI check quite.
The high-tech pacemaker with mixed future
Current, investigator people devote oneself to development to go out not to need to change battery, do not need lead, do not have the pacemaker of pulse generator even, allow a patient can have nothing worry about.
The pacemaker of tradition of ● wireless pacemaker basically includes two shares: Pulse generator and electrode lead. Electrode lead need delivers the electric pulse of pacemaker to the heart, transmit cardiac report activity pacemaker. Embedded when need opens thorax undergo surgery. Once electrode lead dislocation or the insulation layer damaged outside, can cause very troublesome consequence, need operation repair. little electrode lead, can reduce a lot of troubles.
And the wireless pacemaker that there is a kind of miniature now, bulk is the 1/10 of traditional pacemaker only. Embedded when need not open chest, from ham advocate vein guides to the heart but. Pacemaker can stay in heart interior finally, deliver electric pulse to the heart directly, the electrode lead that grows through growing no longer. A few more original because the body is frail and the patient that cannot have surgical operation, also can pass small achieved kind is embedded pacemaker of this kind of miniature. Additional, the n that this kind of pacemaker uses up than traditional pacemaker is little, can full load uses 8 ~ 10 years. The miniature that place of St.Jude Medical company produces is wireless pacemaker has been approved to be used at in Europe clinical.
Pacemaker of miniature of ● biology pacemaker still needs embedded perhaps replace, if can get sth done once and for ever is good. Cedar of American los angeles – hope of accept heart institute can accomplish this on the west. The institute went to look focusing a kind of gene that the name is TBX18, this gene is sent in embryo only normally Yo when ability expression, central Plains of responsible production heart can produce the cell of electric activity naturally originally. In the experiment, researcher injects these gene in the heart that has the pig that conducts block sluggish purposely, as a result cell of one fraction target became cell having fight inside 48 hours, can deliver electric pulse to the heart. The two weeks result that monitor shows, after accepting remedial pig to be in can normal activity, the heartbeat is normal in all sorts of activities.
Investigator thinks, the effect of pacemaker of this kind of biology may be permanent, need to have injection only that is to say. Gene by infuse heart hind, the cell can resemble becoming cell having fight in that way during embryonic development, and permanent maintain this kind of position. Investigator hope can be inside 3 years on human body have clinical trial. Inchoate test may is aimed at first the patient that produces infection because of pacemaker and what conduct block sluggish purposely is fetal (in before, those who have this problem is fetal cannot treat) .
The illness that ● does not have patient of electric pacemaker even if is not serious, doctor level is high, the batteries of pacemaker is the longest also can use 15 years only. If patient life is enough long, must be faced with change the problem of batteries, this increased the risk of infection. Development of group of a scientific research goes a kind of pacemaker, can get from inside the natural movement of human body organ enough the electric power that keeps oneself movement, achievement is released in ” journal of national academy of sciences ” on monthly magazine.
This kind of pacemaker will achieve the sources of energy from heart and lung. In the experiment, the energy of this kind of pacemaker is made implement can be in the heart beats or 3.7 ~ are made when lung breath every time voltage of 8 bend over, the locomotive place that can satisfy oneself completely needs. Since need not change battery, whether can this kind of pacemaker use a patient to die to also do not damage all the time? Investigator in lab lieutenant general its around bent 20 million times, also did not discover fatigue evidence, wear well of it may be said.
The pacemaker that ● is not afraid of MRI is embedded the patient of pacemaker cannot accept nuclear magnetic resonance become quite picture (MRI) examination, the powerful magnetic field that produces because of MRI scanner and radio frequency pulse may disturb the setting of pacemaker or cause electrode lead overheat, produce accident stimulation to the heart, cause appliance trouble finally or the heart organizes injury. But about the half is embedded the patient of pacemaker needs to accept MRI inspection, because other and video examination cannot resemble MRI,acquire the image with organ, parenchyma, skeleton and tectonic interior of someone else system in detail euqally.
The pacemaker of Revo MRI SureScan that company of beautiful force honest makes is nonexistent however these hidden trouble. It has a function, before MRI scans open, can have made the preparation that accepts scanning for the patient, be not harmed. In clinical trial, have 221 patients embedded this kind of pacemaker, after accepting MRI to scan, produce complication without one person.
