The normal left ventricular (LV) size and thickness can vary slightly depending on age, gender, and individual factors, but here are the general reference values:
1. **Left Ventricular Internal Dimension (LVID)**
- **End-diastolic LVID**: Around **4.6 to 5.7 cm** in adults.
- **End-systolic LVID**: Around **2.5 to 3.4 cm** in adults.
2. **Left Ventricular Wall Thickness**
- **End-diastolic wall thickness** (septal and posterior wall):
- **Male**: Typically between **0.6 to 1.1 cm**.
- **Female**: Typically between **0.6 to 1.0 cm**.
These values are measured during an echocardiogram (ultrasound of the heart). If the LV size or thickness is outside the normal range, it could indicate certain heart conditions, such as hypertrophy (thickening of the heart muscle) or dilatation (enlargement of the heart chamber).
