Twelve Leads Electrocardiographic Expressions at Different Body Positioning

The heartbeat is a result of electrical conduction in the heart. The heart's contractions release electrical signals that trigger the heart muscle to pump blood to the lungs and the rest of the body. An electrocardiogram (ECG) records these electrical signals from each heartbeat, allowing for the observation of heart rhythm and the assessment of any abnormalities in electrical conduction. The ECG is a non-invasive monitoring tool used for evaluating heart health throughout the perioperative period and for checking the function of pacemakers. By analyzing the shape, size, and time intervals of these waveforms, ECGs provide visual representations that help healthcare professionals assess conditions related to heart valve diseases.

The 12-lead ECG is considered the gold standard for evaluating cardiac structure and diagnosing various heart conditions. This system consists of twelve leads created from ten electrodes, recording the heart rates electrical activity from different angles in three-dimensional space to understand the condition of various heart regions. Currently, 12-lead ECG machines are widely used in emergency and ambulance settings. They often incorporate integrated electrode patches that replace the traditional ten individual electrode patches, significantly simplifying the process and reducing errors. This integration improves signal transmission and quality compared to traditional ECG leads. Data is transmitted wirelessly, paired with mobile device software, and sent to the cloud to support diagnostic reports.

This study is an observational research project aimed at establishing and analyzing 12-lead ECG data. The goal is to utilize this data for more in-depth diagnostics and to observe its differences and clinical applications.
