In healthy hearts, electrical impulses travel through the heart muscle in an orderly manner to control the contractions of the cardiac cycle and facilitating at regular intervals. However, when the electrical impulses that travel through the heart of chaos, it disables the rate constant and prevents the body from blood flow.This video shows arrhythmias during fibrillation, showing the dynamics of space-time very complex. From the frame 1700, low-energy pulses are introduced gradually and can see the time and the eventual termination of the arrhythmia. jwplayer configuration ; mp4 one of these disorders rhythm, called atrial fibrillation is the most common cardiac arrhythmia in the world, affecting approximately 1 % of the population, especially those aged 50 years.
Older people explains in the story that her husband died more than 20 years ago, while his two sons live abroad. He complained of injuries that a battery of tests can not confirm to prolong his stay in hospital for a short time before breaking down. ‘It ‘s just that I’m alone and there are many hours of the day,’ he said before letting out a sound that is neither desperate laugh or cry. ‘Doctor,’ asks, ‘can you give me a remedy against loneliness?’
The new technique, which is stated in the edition of the journal Nature on July 14, reduces the energy needed for defibrillation by 84 % over traditional methods.
The new method ends turbulent electrical activity in the heart of every step. In experiments and computer simulations, researchers have shown that the natural heterogeneity in the heart, blood vessels, in particular, can act as the origin of the synchronization of the waves. The weak electrical signals are sufficient to create virtual electrodes that stimulate the cells in these regions, said Eberhard Bodenschatz, MPI Director of DS and Cornell assistant professor of physics and mechanical and aerospace engineering.
Why do researchers believe that the revolutionary leap, they work to get to patients as quickly as possible.
The energy applied to the wrist heart is on average 84 % less than traditional methods, said Fenton.
With each additional impetus to the heterogeneity in the heart are more activated and gradually suppress the chaotic activity and reprogram the heart.
