Pacemaker Wireless - a new solution to an old problem

The normal heart has its own pacemaker that regulates the rate at which the heart beats. However, pure heart pacemakers may malfunction, causing slower heart rate. This condition is known as heart block, and can cause symptoms such as dizziness, shortness of breath or a blackout. In such cases, the implantation of an artificial pacemaker solves the problem .
A pacemaker is a device that monitors the heart rhythm and provides electrical stimulation when the heart beats too slowly. It consists of a battery-powered generator that produces the electrical impulses that travel along an insulated wire (lead) at the apex of the heart.
Since its first introduction in 1958 , pacemakers have been innovations size, design and functionality. Pacemakers are now smaller , but more efficient . So far, however, require surgical implantation , which exposes the patient to risks of infection, bleeding and accidental lung injury. Lead is also sensitive to displacement or rupture , for which there are restrictions on the lifestyle of the patient.
The recent development of end systems pacemaker child is likely to solve many potential problems associated with conventional pacemakers. Leadless pacemaker generator consists of a pen-shaped batteries miniature could be inserted under local anesthetic into a vein in the groin , got into the heart chamber and positioned at the apex of the heart. Since the generator is in direct contact with the heart , no leads required to send current to the heart muscles. 

With this new technique , the potential risks of surgical implantation and development of scar tissue at the site of a surgical incision could be avoided. Furthermore, the absence of a probe obviates the need for a life style restrictions. In addition , these pacemakers also can be easily recovered from a similar procedure after implantation battery life is exhausted or if replacement is necessary for any reason way .
The first human implant of a pacemaker lead was conducted at Mount Sinai Hospital in New York in 2014. Already found in the order of ideas, the approach is less invasive compared with traditional pacemaker heart requires more extensive surgery . The average duration of about 30 minutes. Even with miniaturization , the device's battery should have a half- life of ten to thirteen years . 
More than 4 million people worldwide have a pacemaker and an additional 700,000 patients receive the device each year. In such a scenario , medical technology is something we can turn to when needed, and no reason to rejoice in it.
