Interventricular septal thickness at end-diastole. Normal range 0.6-1.0 cm (men) or 0.6-0.9 cm (women).

LV geometry: Normal geometry. LV mass 147.8 g, LVMI 77.4 g/m².

  • LVMI is 77.4 g/m², within the normal range for men (normal up to 115 g/m²).
  • Relative wall thickness is 0.38, at or below 0.42, consistent with an eccentric or normal pattern.
  • Both LVMI and RWT are within published normal limits.

Next stepThese values are derived from echocardiographic measurements and should be interpreted by a cardiologist in the context of clinical history, blood pressure, symptoms and other imaging findings.
