ECG Interpretation and Heart Activity

The video tutorial introduces the concept of ECG, explaining its significance in monitoring the heart's electrical activity. It covers the basics of ECG, including its components like the P-Wave, QRS complex, and T-Wave, and how these are used to assess heart function. The tutorial also discusses the use of leads in measuring ECG and highlights common cardiac disorders that can be diagnosed through ECG readings.
