Heart is probably one of the most favourite organs for poets and singers alike! Starting from ‘My heart will go on’ (which is now so famous that it is one of the most irritable songs for many!) to ‘dil ki dhadkan’; lyricists and singers would be unemployed if it were not for the heart!
Pages after pages are written everyday about the heartbeat! How it increases when you look at someone or think about someone or something! Or when someone steals your heart! Or when your ‘heart’ is not in the right place or when the heart no longer beats for someone or something!
You can be ‘heartless’ in spite of a beating healthy heart! Or you can have a ‘hearty’ meal when it is the stomach which is full!
It is all in the heart!
The interesting thing is that the whole beat starts in a single point!
It is also interesting to note that this is the only organ which has to beat constantly every single day and minute! In a heart transplant or in some surgeries it is literally stopped and restarted! The whole surgery depends on the ability of the heart to restart! Constantly this little pump beats and pumps blood over and over again!
Now you may wonder that since most of the ‘heart’ related feelings are expressed by men; this may be the reason of calling the connecting bundle between the two chambers of heart as Bundle of HIS! Well, before you take out the sexist spears let me assure you that it is not so!
So, in the year 1839, Jan Evangelista Purkinje discovered a net of gelatinous fibres in the subendocardium of the heart which are named after him!
Later on a conducting bundle between the atrium and the ventricle was found by Wilhelm His, Jr in 1893! (THAT’S WHY ITS CALLED BUNDLE OF HIS! NOTHING MASCULINE ABOUT IT!)
Later on in 1906, Sunao Tawara found a “complex knot” of tissue at the proximal end of the His bundle. He concluded that this was the inception of an electrical conducting system which continued from the AV node through the bundle of His, divided into the bundle branches, and terminated as the Purkinje fibres. Finally Arthur Keith and Martin Flack discovered the sinus node which is the beginning of your heart beat!
The sinus node is thus the beginning of your heart beat! So if you want to be technically true poet or if you are a medico who likes a Cardiologist then you can write about the SA node to impress him or her!
Then again if your heart is not in it then it may not be that ok! Dun kya!
Now calm your heart and sleep!
Shubh ratri!
