ECG Interpretation involves analyzing the electrical activity of the heart as recorded by an electrocardiogram (ECG or EKG). This process helps identify various heart conditions by examining the heart's rhythm, rate, and overall function. Key components include the P wave, QRS complex, and T wave, which represent different phases of the heart's electrical cycle. To interpret an ECG, healthcare professionals look for abnormalities in these components, such as irregular rhythms or signs of ischemia (reduced blood flow). Accurate interpretation is crucial for diagnosing conditions like arrhythmias, myocardial infarction, and other cardiac issues, guiding appropriate treatment.
