    Measuring the Mean QRS Electrical Axis in an ECG
    (2024) Garrison, Ryan, Osteopathic Medical Student; Dang, Kim Chi, Osteopathic Medical Student; Carter, Reagan, Osteopathic Medical Student; Loomis, Mario, Associate Professor Clinical Anatomy; Alvarez, Diego F, Professor Physiology and Pharmacology
    In this episode of the Loomis-Alvarez Medical Video Series, we unlock the electrocardiogram (ECG) mastery in deciphering the Mean Electrical Axis of the heart by using different approaches. In this educational video, we dive into the intricacies of electrocardiography (ECG) to determine the mean electrical axis of the heart. Led by our medical students, this tutorial aims to equip students, residents, and enthusiasts alike with the knowledge and skills needed to accurately interpret ECGs. Throughout the video, viewers will be guided step-by-step through different approaches for calculating the mean electrical axis, a crucial aspect of ECG interpretation that provides valuable insights into cardiac health and function. Starting with a brief overview of the vectorcardiogram principle, the tutorial gradually progresses to analyze the information generated in an ECG and apply it to interpret waveforms and their relation with the vectorial movement of electrical cardiac depolarization defining in its path a mean electrical axis. Detailed instructions on how to determine an electrical axis are laid out and clinical implications from real-life examples are presented. Featuring clear explanations and illustrative diagrams this video offers a guide to mastering the calculation of the mean electrical axis. Whether you are a medical student or a medical resident, this tutorial is sure to enhance your ability in ECG interpretation and contribute to better patient care.
