Cardiology is one of the most intricate fields of medicine man has ever explored.
The heart is such a complicated piece of biological marvel that many people attribute it a higher function than even the brain.
The basic premise of cardiology is the human heart.
It involves studying the heart to find out how it works.
It also tries to find out the various diseases and conditions that can affect the heart.
The aim of cardiology is to find solutions to these problems and improve the durability of the human heart.
The heart is the blood pump of our body.
It pumps oxygenated blood it receives from the lungs to various parts of the body.
It takes in the deoxygenated blood from all the organs and sends it back to the lungs.
This cycle starts even before our birth and goes on until we die.
Heart is the most efficient machine known to man.
During the ancient times, heart was wrongly thought to be a hydraulic pump.
Instead of relying on the pressure of the liquid to propagate the blood, heart actually uses small electric pulses that keep it ticking.
The heart muscles contract every time it gets an electric impulse.
This sends the blood out into the body.
And then it eventually relaxes.
This process goes on indefinitely.
Many heart problems are caused due to irregularity in the generation of these pulses that can cause the heart to function in an erratic fashion.
If the damage isn't permanent, the cardiac pacemaker, the system involved in creation of the pulses can be 'reset' by applying a small voltage at the right points.
Almost everyone would've seen a scene of this happening in movies where the protagonist lies on the floor clutching his heart, and a doctor tries to save him by placing paddles on his chest and pressing hard.
Obesity is another major concern among cardiologists.
The excess fat in the body means excess fat in the blood.
Fat and cholesterol are made of sticky substances that tend to deposit on the arterial walls of the heart, thus constricting the flow of blood.
When this gets out of hand and a pathway is blocked, the patient offer suffers from extreme pain in his heart and sudden onset of dizziness.
This is commonly referred to as a heart attack.
It has to be treated immediately by taking the victim to a hospital emergency ward.
Congenital heart problems refer to issues of the heart that are caused by structural or functional disorder of the heart muscles to fill the heart with blood to pump out.
High bloody pressure often is a reaction of overworking heart due to improper cardiac functioning.
On the other hand, low blood pressure can be cause by an improperly functioning heart that is not able to pump enough blood.
The advances made in cardiology in the last few decades are phenomenal.
These technological innovations give our doctors the tools to diagnose and fix many complicated heart problems, thus improving our standard of life.
