What is the primary purpose of an electrophysiology study?

The primary purpose of an electrophysiology study is to evaluate the electrical activity of the heart and investigate arrhythmias. This procedure involves inserting catheters into the heart's chambers to assess the heart's electrical conduction system and identify any abnormalities that may be causing arrhythmias. By mapping the electrical pathways and assessing how they function, healthcare providers can determine the site and mechanism of arrhythmias, and subsequently decide on appropriate treatment options.

The other options, while related to heart health, do not accurately reflect the specific focus of an electrophysiology study. For example, measuring blood pressure is a straightforward assessment of circulatory function, performing a biopsy of heart tissue involves obtaining a sample for histological examination, and assessing the heart's pumping efficiency pertains more to evaluating its mechanical function rather than its electrical properties.
