Introduction to ECG Interpretation\n\nAn electrocardiogram (ECG/EKG) is a graphical recording of the heart's electrical activity measured by electrodes placed on the skin. The interpretation of the ECG provides information about cardiac rate, rhythm, conduction, hypertrophy, ischemia, and much more. Mastering ECG interpretation requires systematic analysis and pattern recognition, underpinned by core knowledge of cardiac physiology and pathology.\n\nA conventional 12-lead ECG utilizes ten electrodes and offers twelve electrical perspectives of the heart. Deviations from normal waveforms, intervals, and axes indicate a range of cardiac and metabolic conditions. Clinicians rely on ECG interpretation for diagnosis, monitoring, and management of cardiac patients in both outpatient and emergency settings.","metadata":{"_uuid":"760613f4-b1a1-4068-be4d-6e0c2b3a440b","_cell_guid":"7afbb256-9b95-46ff-afa9-177d1fb2196c","trusted":true,"collapsed":false,"jupyter":{"outputs_hidden":false}}},{"cell_type":"markdown","source":"## 2. Fundamentals of Cardiac Electrophysiology\n\nThe cardiac cycle is orchestrated by the electrical conduction system and reflected in the ECG. Electrical impulses that initiate heartbeats originate in specialized pacemaker cells and propagate through the myocardium, leading to coordinated contractions.\n\n\n
