Teichholz |
Method (formula) for calculating left ventricle volumes and function derivatives (EF, SV, SI, etc.) Volume = [7.0/(2.4+D) ]*D3. |
125208
|
Method of Disks, Single Plane |
Method of calculating volume based on the summation of disk volumes. The disk axis is parallel to the left ventricular long axis with disk diameter taken from the four-chamber view. |
125207
|
Method of Disks, Biplane |
Method of calculating volume based on the summation of disk volumes. The disk axis is parallel to the left ventricular long axis and using a disk diameter averaged from the two chamber and four chamber views. |

|
Cube Method |
Method (formula) for calculating left ventricle volumes and function derivatives (EF, SV, SI, etc.) that estimates the volume as the cube of diameter. |

|
Bullet Method |
Bullet method of estimating ventricular volume.Volume = 5/6 * L * SL: Left ventricle long axis lengthS: Left ventricle area, SAX view at level of Mitral Valve. |
125205
|
Area-Length Single Plane |
Method for calculating left ventricular volume from a view containing the true long axis (usually the apical 4-chamber view). Volume = [8(A)2]¸[3pL]. |

Modified Simpson |
Modified Simpson's Method of estimating ventricular volume, based on the method of disks with paired apical views.Schiller NB, et al. "Recommendations for quantitation of the left ventricle by two-dimensional echocardiography. American Society of Echocardiography Committee on Standards, Subcommittee on Quantitation of Two-Dimensional Echocardiograms". J Am Soc Echocardiogr.1989 2(5):358-367. Sep-Oct. |

|
Area-Length Biplane |
Method for calculating left ventricular volume from two orthogonal views containing the true long axis (usually the apical 4 and 2 chamber views). Volume = [pL1 / 6] * [(4A1) ¸ (pL1) ] * [(4A2) ¸ (pL2) ]. |

|
Single Plane Ellipse |
Method of estimating volume from a planar ellipse. Equivalent to Biplane Ellipse with an assumption that the ellipse in the orthogonal plane has identical major and minor diameters. |
