Although it is controversial what exactly has initiated the vitalization, we know quite well how it ends. The heart stops. And just like a closing switch, when the heart stops, the entire body and consciousness fall into a deep sleep. Therefore, to understand and monitor the function of the heart 1 might mean to understand the functioning of the whole body and even the existence.
Even though the heart seems to be related to the world of wisdom, spirituality and emotion in almost all of the ancient cultures, its purpose in the western science is accepted to pump and distribute blood 2. As a result of the neuro-cardiac studies, the heart has found to be a small brain 3 with about forty thousand neurons at the same time. Thus we have learned the heart has functions to feel 4, make decisions, to initiate hormone produce, and even to learn and remember. In addition, we have also discovered that the heart communicates the brain to trigger an action plan in emotional situations such as fear, stress 5, joy, and compassion. In order to understand the human of tomorrow, it is necessary to follow the heart and understand its language.
ECG testing, which is performed to evaluate the electrical and muscle activity of the heart, brings gels and jumbled cables come to mind. These scenarios are about to become history. The water resistant wearable devices collect 20 million data points per day and send the test results to your smartphone, talk to your doctor and follow your heart health closely.
Artificial heart has become the most noteworthy product of 3D printers in the health sector. The silicone heart, produced by the Swiss Institute of Technology without a touch of hand, can fulfill a real function of the heart. It's a matter of time that arrhythmia cease to exist through the world's smallest pacemaker, designed in the Houston Methodist hospital..
We learned in the science class that the heart works through the commands of the brain. As for the truth revealed by the studies in the neuro-cardiac field, the heart sends much more commands to the brain! emWave device, developed by the HeartMath Institute, can track how the emotions change the heart rhythm and how it affects the brain functions.
As the terms such as neuropsychiatry, neuroeconomics emerge with the discovery of impacts of out feelings to our decisions, we continue to learn its effects on the body such as the feeling of fear to accelerate the heartbeat and respiration, and to cause the secretion of the adrenaline hormone. These discoveries are expected to lead to the dissolution of the mystery between the body and the consciousness.
Whereas the discovery of emotions plays a role in the heart function, "stress" draws the most attention. While being stressed at a certain level increases productivity, focusing and attention, it leads to different results as the threshold value is exceeded. The study published in Lancet showed that the stress-induced brain increased the risk of heart and vascular disease in patients with active amygdala section. Managing stress will also be one of the main issues of the human of tomorrow.
