Vectorcardiography is a method of recording the magnitude and direction of the electrical forces generated by the heart over time, providing a three-dimensional representation of the heart's electrical activity. It offers a more comprehensive view than a standard electrocardiogram, potentially improving the diagnosis of certain cardiac conditions.
Specificity refers to the ability of a test to correctly identify those without the condition, minimizing false positives. It is a crucial metric in diagnostics, ensuring that healthy individuals are not misclassified as having a disease.
Consistency refers to the steadfast adherence to the same principles or course of action over time, which fosters reliability and trust. It is essential in various fields, from personal habits to business practices, as it creates predictability and stability, allowing for the measurement of progress and effectiveness.
