The heart is the engine at the centre of the body’s circulation system. It starts working even before we are born – and from the on, it beats constantly, throughout our lives.
Made from a special kind of muscle not found anywhere else in the body, the hardworking heart contracts and relaxes about 70 times every minute. This rhythmic pumping pushes essential blood out to the body, then fills the heart up again, ready for the next beat.
The performance of the heart could now be easily monitored when any cardiovascular problem or disorder is suspected. For instance, a regularly abnormal heartbeat or beats per minute are characteristic of a heart-related illness. This is because a heartbeat is a manifestation of the oxygen-reloading process in the heart that is made up of two phases.
