The electrocardiogram (ECG or EKG) is the gold standard for non-invasive cardiac monitoring, providing a graphic representation of the heart’s electrical activity over time. Each heartbeat generates a specific series of electrical waves and intervals—known as the PQRSTU complex—that correspond to distinct mechanical events within the cardiac cycle. Mastering the morphology and duration of these components is essential for clinicians to accurately diagnose arrhythmias, conduction blocks, and myocardial ischemia.

The 12-lead electrocardiogram (ECG) is the cornerstone of modern cardiac diagnostics, providing a comprehensive visual representation of the heart's electrical activity. By analyzing the specific waveforms and intervals captured on the grid, healthcare professionals can assess the integrity of the cardiac conduction system, identify rhythm abnormalities, and rule out acute events such as heart attacks. The image provided illustrates a standard clinical report showing a "Normal Sinus Rhythm," serving as a perfect baseline for understanding healthy cardiac physiology.

A 12-lead electrocardiogram (ECG) is a fundamental diagnostic tool used in cardiology to visualize the electrical activity of the heart from multiple angles. The image provided displays a standard report generated by a Nihon Kohden Corporation device, showcasing a "Normal Sinus Rhythm." This printout translates the invisible ionic currents of the cardiac muscle into a graphical format, allowing clinicians to assess heart rate, rhythm, and the integrity of the conduction system. Understanding the layout of the grid, the specific waveforms, and the standard intervals is essential for distinguishing a healthy heart from one experiencing pathology.
