Which of the following abbreviations indicates a cardiac condition?

The abbreviation "VT" stands for "ventricular tachycardia," which is a specific type of arrhythmia involving the heart's ventricles beating at an abnormally fast rate. Ventricular tachycardia is indeed a serious cardiac condition, as it can lead to complications such as decreased cardiac output and may result in loss of consciousness or even cardiac arrest if not treated promptly.

Understanding medical abbreviations is crucial in the healthcare setting, especially in relation to cardiac conditions. This knowledge helps in quick recognition and response to potentially life-threatening situations. The other abbreviations, while useful in different contexts, do not specifically relate to cardiac conditions: for example, "VS" typically stands for "vital signs," "WDWN" indicates "well-developed, well-nourished," and "WNL" means "within normal limits."
