Cardiovascular centre the cardiovascular centre and cause it to increase the rate of impulses sent to the sinoatrial node, or pacemaker, resulting in faster and stronger cardiac muscle contraction and thus increasing the heart rate. Cardiovascular centre The cardiovascular centre is a part of the human brain responsible for the regulation of the rate at which the heart beats through the nervous and endocrine systems. It is found in the medulla oblongata. Normally, the heart beats without nervous control, but in some situations (e.g., exercise, body trauma), the cardiovascular centre is responsible for altering the rate at which the heart beats. It
Cardiac contractility modulation heart structure can be partially reversed by Cardiac contractility modulation through a process known as reverse remodeling of the heart. Development of cardiac contractility modulation began in the late 1990s. Studies on individual cardiac muscle cells using a patch-clamp technique had already shown, in 1969, that a voltage applied during the absolute refractory period through leads between the interior of the cell and its outside environment increased the calcium influx through the cell membrane and improved the contraction of cardiac muscle cells. In 2001, scientists observed that a similar effect occurs even if the voltage is applied exclusively outside the
