Szívbeömléscsökkenés

Szívbeömléscsökkenés is a Hungarian term that translates to "decreased filling of the heart" or "reduced cardiac filling." It refers to a condition where the heart's chambers, particularly the ventricles, do not receive an adequate amount of blood during diastole, the relaxation phase of the cardiac cycle. This reduced filling can lead to a diminished stroke volume, meaning the heart pumps less blood with each beat, potentially compromising the body's oxygen supply.

Several factors can contribute to szívbeömléscsökkenés. These include conditions that impair the heart's ability to relax and fill properly, such as restrictive cardiomyopathy, where the heart muscle becomes stiff and less pliable. Tamponade, the accumulation of fluid in the pericardial sac surrounding the heart, can also compress the chambers and restrict filling. Similarly, severe valve stenosis, particularly mitral stenosis, can impede blood flow into the ventricle. Additionally, certain arrhythmias that lead to excessively rapid heart rates can shorten the filling time, preventing adequate blood entry.

The symptoms associated with szívbeömléscsökkenés often depend on the underlying cause and the severity of the reduced filling. Common manifestations include shortness of breath, particularly during exertion, fatigue, dizziness, and palpitations. In more severe cases, it can lead to heart failure. Diagnosis typically involves a combination of medical history, physical examination, electrocardiogram (ECG), echocardiogram (ultrasound of the heart), and other cardiac imaging techniques to assess chamber size, wall motion, and blood flow. Treatment strategies are directed at addressing the root cause and improving the heart's filling dynamics.
