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). Courtesy of Dr. Mark D. Kittleson.

2009年10月14日 · Preoperative (A) and 4 months postoperative (B) lateral radiographs of a 6-year-old miniature Poodle with patent ductus arteriosus. The chest depth decreased and VHS decreased from 13.4v to 10.8v after PDA closure.

Consult this peer-reviewed comprehensive guide for calculating a vertebral heart scale in dogs to gain insight into its uses and how to interpret findings.

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 …

In dogs with MVD, an increased VHS is strongly suggestive of cardiomegaly. The degree of cardiac enlargement is dependent on the stage and severity of the underlying disease and is reflected by an increase in VHS measurement.

2023年1月9日 · Vertebral heart score (VHS) and vertebral left atrial size (VLAS) are the objective measures of cardiac and left atrial sizes on thoracic radiographs in dogs. Previous studies have demonstrated that the normal VHS reference ranges can vary among breeds.

2016年4月8日 · VHS is useful for monitoring a patient in which heart disease is suspected (Figure 1), or in tracking changes in progressive cardiac disease over time. Figure 1. Illustration of VHS calculation in a normal dog. On a lateral radiograph, a line is drawn from the carina to the most ventral aspect of the heart. This line is the “L” or long axis line.

This prospective study aims to establish reference ranges for vertebral heart score (VHS), vertebral left atrial size (VLAS), and radiographic left atrial dimension (RLAD) in pugs.

Breed-specific values for vertebral heart score (VHS), vertebral left atrial size (VLAS), and radiographic left atrial dimension (RLAD) in pugs without cardiac disease, and their relationship to Brachycephalic Obstructive Airway Syndrome (BOAS).

However, several studies have shown significant breed variations from the value previously established by Buchanan and Bücheler (9.7 ± 0.5). This study describes VHS measurements in Pug, Pomeranian, Yorkshire Terrier, Dachshund, Bulldog, Shih Tzu, Lhasa Apso, and Boston Terrier dog breeds.
