Häufig gestellte Fragen

What does the heart do?
The heart is a muscular organ that pumps blood throughout the body via the circulatory system. It beats approximately 60–100 times per minute at rest, circulating oxygenated blood to tissues and returning deoxygenated blood to the lungs. It consists of four chambers: two atria and two ventricles.
Where is the heart located?
The heart is located in the mediastinum, the central compartment of the thoracic cavity, between the lungs. It sits behind the sternum and slightly to the left of the midline. It rests on the diaphragm and is enclosed in a protective sac called the pericardium.
What are common conditions affecting the heart?
Common heart conditions include coronary artery disease, heart failure, arrhythmias (abnormal heart rhythms), myocardial infarction (heart attack), and cardiomyopathy. Valvular disorders such as aortic stenosis and mitral regurgitation are also frequently encountered in clinical practice.
