This presentation by Dr. Dariush Abtahi provides a comprehensive overview of electrocardiogram (ECG) interpretation, focusing on the standard 12-lead ECG and its components. It covers key waves and intervals, including the P wave, QRS complex, ST segment, T wave, and U wave, as well as their significance in assessing cardiac function. The presentation explains how to measure intervals such as PR, QRS duration, and QT, and outlines the normal ranges for these measurements. It also addresses abnormalities, such as bradycardia, tachycardia, prolonged or shortened PR intervals, bundle branch blocks, and long QT syndrome, which can indicate underlying heart conditions. Additionally, it discusses axis deviations, both left and right, and their potential causes, such as myocardial infarction or congenital heart defects. The presentation emphasizes a systematic approach to ECG interpretation, including analyzing heart rate, rhythm, conduction, and waveform morphology, while comparing findings to previous ECGs when available. This method ensures accurate diagnosis and understanding of cardiac pathologies.
