The VHS measurement is a useful tool to establish whether a dog with mitral valve disease (MVD) has an enlarged heart (cardiomegaly). This is important since dogs with asymptomatic MVD and cardiomegaly will benefit from treatment with Vetmedin®1. In dogs with MVD, an increased VHS is strongly suggestive of cardiomegaly.

You can use VHS calculations to help identify dogs with advanced preclinical mitral valve disease. For more information, visit www.epictrial.com. Reference: 1. Buchanan JW, Bucheler J. Vertebral scale system to measure canine heart size in radiographs. J Am Vet Med Assoc. 1995;206(2):194–199.

2016年4月8日 · The reference values for vertebral heart scale measured on VD and DV radiographs are 9.4-11.0 and 8.8-11.7, respectively, for dogs. 11 The published range for a normal VHS is 9.2-10.3 on a lateral radiograph, with 10.5 suggested as the cutoff for clinical determination of cardiomegaly in adult dogs. 11

2022年7月6日 · The objectives of this update are to review the techniques for measuring and interpreting both VHS and VLAS, provide meaningful cutoff values that can used in clinical practice, and review the radiographic diagnostic criteria for …

This radiograph of a normal dog shows the length (red lines) of the heart to be 5.5 vertebrae and the width (blue lines) 4.5 vertebrae. The VHS is therefore 10 vertebrae (V).

VHS = vertebral heart scores ，犬隻椎體心臟評分，是藉由x光建創一種更客觀診斷心臟擴大的分級數值，因為個體差異，狗狗可能具有超過正常範圍的值但沒有心臟病，因此不能將此方法用來診斷患者心臟病的唯一方式。 不過，VHS可以用來提高臨床獸醫師對於心臟病的懷疑，也可以用來監測患有心臟病患者，或是追蹤心臟病犬隻隨時間變化的進展。 動物左側躺拍攝動物胸腔x光，在x光上拉出心臟長軸（L）與短軸（S），長軸是氣管分叉處到心間的距離，短軸是心臟後緣垂直 …

The most common cardiac measurements on thoracic radiography in veterinary medicine are vertebral heart size (VHS) and vertebral left atrial size (VLAS). Previously published studies have demonstrated evidence that reference ranges for these measures vary among different dog breeds, however referenc …
