What is an implantable pacemaker?

Implainable pacemaker, also known as an artificial pacemaker, is an internal medical device that regulates the beatings of the heart at sufficient speed that suits the needs of the body. This type of pacemaker is used in patients whose heart rate is too fast, a condition called tachycardia; whose heart rate is too slow, called bradycardia; or who have blocking that prevents the right work of the heart power lead. The implantable pacemaker works by sending electrical impulses through electrodes to the heart, stimulating the heart to download and regulate the heart rhythm. The implantable defibrillator is often used in conjunction with an implantable pacemaker to prevent cardiac arrest. Arne Larsson was the first recipient of their creation. This implanted cardiac only lasted three hours and Larsson continued to receive another 25 pacemaker before his death in 2001. Subsequent implantable designs of cardiosThe Timulator had no lengthy lifetime due to technological barriers to energy sources. Soon pacemakers usually relied on the mercury battery, but the invention of Wilson Greatbatch from the Lithium-nod cell significantly increased the life of the pacemaker and became a standard energy source for modern implanted cardiac, which usually lasts for five to 10 years.

There are three main types of implanted pacemakers: pacemakers with one chambers, dual pacemakers and pacemakers responding to rates. Disposable pacemakers, also known as ventricular demand, have one conductor or stimulating lead, which can connect to the right atrium or right chamber of the heart. These pacemakers send electrical impulses to the heart only as needed, or on the heapoptávka RT. Dual chamber pacemakers have two stimulating lines, one lead to the hall and the other for the chamberto mimic the natural stimulation of the heart. Cardiostimulators responding to rates who could either be single or with a double chamber can use sensors to edit the stimulation to the user's activity level.

Recipients of implanted pacemakers should not notice considerable changes in their lifestyle, even if there are several things to avoid. Cardiostimulator users must avoid strong magnetic fields that can interrupt the function of the pacemaker, including scanning magnetic resonance (MRI) or arc welding. Fully contact sports are also not recommended because contact with the area surrounding the pacemaker can cause serious discomfort. Most household appliances and mobile phones, however, proved to be safe for the recipients of the pacemaker. All cardiac users should undergo periodic checks to make sure the device works properly.
