An electrocardiograph often abbreviated as ECG or EKG, is a medical device used to record the electrical activity of the heart over a period of time. This electrical activity is depicted graphically on a paper or displayed on a screen as a series of waveforms which are known as an electrocardiogram. The electrocardiogram provides crucial information about the heart's rhythm, rate and overall health.
Purpose: A medical device used to record the heart's electrical activity.
Electrodes: Small metal sensors placed on the chest, arms, and legs to detect the heart's electrical signals.
Leads: Specific electrode configurations (usually 12) capture electrical activity from different angles.
Amplification: Weak electrical signals are amplified by the ECG machine.
Waveforms: ECG displays a series of waveforms, including the P-wave (atrial contraction), QRS complex (ventricular contraction) and T-wave (ventricular relaxation).
Interpretation: Healthcare professionals use ECGs to diagnose heart conditions like arrhythmias, ischemia and other cardiac disorders.
Non-Invasive: ECGs are non-invasive, providing valuable insights into heart health without surgery.
Clinical Use: ECGs assist in diagnosing, monitoring and treating heart-related issues and assessing the effectiveness of cardiac treatments.
