Heart Structure
The heart has four rooms. The top is called the atrium or foyer, which has divided into the right atrium and left ventricle while the bottom was called or booth, which has divided into right and left ventricle. The relationship between the porch and chambers and chambers and blood vessels has mediated by the valve.
These valves work to keep the blood flowing in a normal process can not be reversed. That is the purpose of the four pieces of existing valves in the heart, exactly two last valve is the valve between the heart and blood vessels. So the blood only flows in one direction only, namely when the heart contracts.
How to Work Heart
The heart pumps blood to the lungs and into all body tissues with a very regular contractions and sequence. There are differences in atrial and ventricular contractions that cause blood to flow from the atria to the ventricles. To be the heart can work perfectly, the four chambers must contract in an organized heart (not simultaneously).
This is possible because of the electrical impulse. One room at the time the heart contracts electrical stimulation through the room. Signal starting from a place that located in the right atrium called the sinoatrial node (SA node) or sinus node. Failure of this function can make heart failure or slow to beat.
In normal adult beats about 60 to 100 times per minute. In a small child / infant dug faster. But the activity, the emotions and hormonal could affect this rate, so the change dug. Normally, these changes needed to adapt to the needs of the body's metabolism.
If Heart Rate Slowing
Because one thing and another abnormal, heart rate slows down or otherwise someone could be fast. When the heart rate suddenly slowed, particularly blood flow to the brain will also be reduced.
Symptoms are most often found in this situation wasn’t helped when fainting which would cause a stroke.
However, these symptoms can not be felt if the decline occurs slowly beats. Complaints to be vague. At first only a feeling of weakness, easy to achieve, sometimes feeling of flying and finally almost fainting or even fainting to heart failure. The cause of slowing the heart rate, according to Muhammad Munawar, a heart specialist physicians devoted to learning disorders of heart rhythm, a wide range.
Can be categorized cause temporary circumstances such as acute myocardial infarction (heart attack), or electrolyte disturbances due to drugs. The cause of settled as in the process of degeneration of organs.
Although slowing the heart rate is mostly suffered by the elderly, but anak-anak/bayi can also experience it. In this last group most often caused by congenital heart disease. Pacemaker-heart (APJ) is required to correct this state of slowing the heart rate.
