If all the nerves connecting the brain to the heart are cut, how will the functioning of the heart be affected? Could you give a detailed explanation on the relation of brain with heart wrt Homo sapiens?

The heart communicates through the brain via nerves fibres running through the vagus nerve and the spinal column .Nerves connected to the heart regulate the speed with which the muscle contracts. Autonomic nerves connect the brain and spinal cord with our heart.
The medulla is the primary site in the brain for regulating sympathetic and parasympathetic outflow to the heart and blood vessels. The hypothalamus and higher centers modify the activity of the medullary centers and are particularly important in regulating cardiovascular responses to emotion and stress
The vagus nerve has 3 nuclei in the central nervous system (CNS) associated with cardiovascular control: (1) the dorsal motor nucleus, (2) the nucleus ambiguus, and (3) the solitary nucleus. The parasympathetic output to the heart comes mainly from neurons in the nucleus ambiguus and to a lesser extent from the dorsal motor nucleus.The solitary nucleus, being an integrating hub for the baroreflex, receives sensory input about the state of the cardiovascular system
Vagus nerve is known to regulate the heart beat. so if there is damage to this nerve than the heart beat can be increased.
If the vagus nerve is impaired there could be heart failure.
he role of the vagus in controlling cardiac function is essential. Loss of heart rate variability of sinus arrhythmia is a prognostic indicator of cardiac disease including heart failure, arrhythmia's and sudden cardiac death
