Like the human body, the heart has its skeleton. The 4 chambers of the heart are attached to it.
AF is an arrhythmia characterized by chaotic cardiac beats that are irregularly irregular. The heartbeat frequency can even be beyond 150 beats per minute.
Normal heart function is closely linked to oxygenation.
Its precious fuel is delivered to the heart by the coronary arteries. Any reduction in oxygen supply can have serious and sometimes irreversible effects on the heart.
Let’s take a closer look at the coronary arteries.
The electrocardiogram (ECG or EKG) is the recording of the electricity generated by your heart.
The electricity of the heart can be recorded by the installation of small electrical sensors on the skin.
An ECG (or EKG) is specific to each person. It is like a fingerprint.
The heart has an electrical system that synchronizes its contraction efficiently.
The upper chambers, the atria, must first contract to fill the ventricles in the lower part of the heart. These, in turn, will compress and, in an inescapable upward movement, spill their contents into the large vessels at the top.
Tricuspid valves include the pulmonary and the aortic valves. Each has 3 cusps that fit onto a fibrous ring in the cardiac skeleton. These valves separate the pulmonary artery from the right ventricle and the aorta from the left ventricle.
The 2 valves that separate the ventricles from the atria are called atrioventricular valves. The tricuspid valve is located on the right side and the mitral valve is on the left.
Heart rate can be calculated by measuring the pulse. The 2 most frequently used pressure points for taking the pulse are in the neck (carotid artery) and on the wrist (radial artery).
The heart is an almost indefatigable muscular organ. It is located in the center of the thorax.
From the 14th day of fetal life, the heart begins its work. From then on, it is the central engine of blood circulation throughout the body.
In our body, blood pressure is what makes oxygenated blood travel through the arteries. Blood is propelled from the heart to the organs (brain, kidneys, digestive tract, muscles), then the blood returns through the veins to be reoxygenated by the lungs.
This site is intended to provide information and make cardiology comprehensible for all patients; it is not a substitute for a doctor. It does, however, enable a better understanding of how the heart works, the many heart diseases that exist, the tests required to reach a diagnosis, and the drugs and other methods used to treat them.
