The first internal pacemaker was developed in 1958 by Dr. Paul Zoll, who implanted electrodes in the heart to regulate its rhythm. However, the first fully implantable pacemaker was created by Dr. Arne Larsson in 1958 as well, and it was successfully used in a patient. These innovations marked significant advancements in cardiac care, allowing for better management of arrhythmias and heart conditions.
The internal gain of an amplifier is the gain or the amplification factor of the transistor used in it....................it is internal because it is fixed for transistors while manufacturing..................
When an electrical impulse originates from somewhere other than one of the pacemaker sites, it is referred to as an "ectopic impulse." This can occur due to various factors, such as electrolyte imbalances or myocardial irritability, and can lead to arrhythmias. Ectopic impulses can arise from areas within the atria, ventricles, or even the conduction system, often disrupting the normal rhythm of the heart.
internal resistance is always infinite in ideal current source .the internal resistance is in shunt with current source
the laser was invented.....
Because many electronics, like power supplies, have internal energy storage in the form of capacitors. If you were to short the terminals, you would be shorting out the internal capacitors and thus creating a potentially hazardous situation. "Completing the circuit by internal resistance" allows the energy stored in the internal capacitors to bleed off slowly because the internal resistance is larger than a short.
John hopps invented the first external pacemaker. Later Earl Bakken improved this pacemaker by making it battery powered. And then Wilson Greatbatch invented the first implantable pacemaker!
the electronic pacemaker was invented by Edgar H Booth, in 1926, but it was used in 1928.

It was invented at Cornell University by Wilson Greatbatch.

Some people die when their heart beats become irregular. By installing a pacemaker, it gave them 10 to 20 more years of life.
John Hopps, a Canadian, invented the first heart pacemaker. At the age of 21, He was able to build the first pacemaker in 1950.
