LVSF stands for Left Ventricular Systolic Function. It refers to how well the left ventricle of the heart is pumping blood out to the body during each heartbeat. The reference provided also includes "Left ventricular function (LVF)" which may encompass both systolic and diastolic function. However, LVSF specifically concerns the systolic aspect.
Here's a breakdown:
-
Left Ventricle: The main pumping chamber of the heart that sends oxygen-rich blood to the aorta and then to the rest of the body.
-
Systolic Function: The contraction phase of the heart cycle when the left ventricle pumps blood out. Therefore, LVSF specifically measures the effectiveness of this pumping action.
The reference mentions that descriptions such as abnormal, compromised, decreased, depressed, diminished, impaired, or reduced systolic function also indicate issues with LVSF. The term also encompasses systolic failure where severity isn't detailed, but isn't specific to the right ventricle.
In simpler terms:
| Term | Meaning |
|---|---|
| LVSF | Left Ventricular Systolic Function - pumping ability of the heart's main chamber. |
| Abnormal LVSF | The heart isn't pumping blood effectively during contraction. |
