Your coronary heart is divided into the correct and the left aspect. The division prevents oxygen-rich blood from mixing with oxygen-poor blood. Oxygen-poor blood returns to the center after circulating by means of your physique.
- The proper aspect of the center, comprising the correct atrium and ventricle, collects and pumps blood to the lungs by means of the pulmonary arteries.
- The lungs refresh the blood with a brand new provide of oxygen. The lungs additionally breathe out carbon dioxide, a waste product.
- Oxygen-rich blood then enters the left aspect of the center, comprising the left atrium and ventricle.
- The left aspect of the center pumps blood by means of the aorta to produce tissues all through the physique with oxygen and vitamins.
Coronary heart valves
4 valves inside your coronary heart maintain your blood shifting the correct approach by opening just one approach and solely when they should. To perform correctly, the valve have to be fashioned correctly, should open all the way in which and should shut tightly so there is not any leakage. The 4 valves are:
A beating coronary heart contracts and relaxes in a steady cycle.
- Throughout contraction (systole), your ventricles contract, forcing blood into the vessels to your lungs and physique.
- Throughout leisure (diastole), the ventricles are stuffed with blood coming from the higher chambers (left and proper atria).
Your coronary heart’s electrical wiring retains it beating, which controls the continual alternate of oxygen-rich blood with oxygen-poor blood. This alternate retains you alive.
- Electrical impulses start excessive in the correct atrium and journey by means of specialised pathways to the ventricles, delivering the sign for the center to pump.
- The conduction system retains your coronary heart beating in a coordinated and regular rhythm, which retains blood circulating.

- Some over-the-counter drugs, prescription drugs, dietary dietary supplements and natural treatments
- Valvular coronary heart illness
In a wholesome particular person with a traditional, wholesome coronary heart, it is unlikely for a deadly arrhythmia to develop with out some exterior set off, comparable to an electrical shock or the usage of unlawful medication. That is primarily as a result of a wholesome particular person’s coronary heart is free from any irregular situations that trigger an arrhythmia, comparable to an space of scarred tissue.
Nevertheless, in a coronary heart that is diseased or deformed, the center’s electrical impulses could not correctly begin or journey by means of the center, making arrhythmias extra prone to develop.
Causes of congenital coronary heart defects
Congenital coronary heart defects normally develop whereas a child is within the womb.

It could be brought on by diminished blood movement to the center (ischemic coronary heart illness) ensuing from harm after a coronary heart assault, infections, toxins and sure medication. It can also be inherited from a mum or dad. It normally enlarges (dilates) the left ventricle.
- Hypertrophic cardiomyopathy. This kind, wherein the center muscle turns into abnormally thick, normally is inherited. It may well additionally develop over time due to hypertension or growing old.
