ECG is a technique to record the activity of?

ECG, which stands for Electrocardiogram, is a well-known medical diagnostic technique that records the electrical activity of the heart over a period of time. Every student must remember that ECG is exclusively related to the heart and is one of the most frequently performed tests in modern cardiology.

• Electrical Activity: Each time the heart beats, it generates electrical impulses — ECG captures and records these impulses in the form of waves
• Electrodes Placement: Small electrodes are carefully attached to the chest, arms, and legs to pick up heart signals from different angles
• Waveforms: ECG produces three characteristic waves — P wave, QRS complex, and T wave — each representing a different phase of the cardiac cycle
• Diagnosis: Doctors use ECG to detect heart attacks, irregular heartbeats, blocked arteries, and other serious cardiac conditions
• Non-Invasive: ECG is completely painless, safe, and takes only a few minutes — making it the first choice for heart examination
