Here’s a brief comparison between ECG (Electrocardiogram) and Echocardiogram:

Feature	ECG (Electrocardiogram)	Echocardiogram
Purpose	Measures the electrical activity of the heart.	Uses sound waves to create images of the heart’s structure and function.
How It Works	Records the heart’s electrical impulses through electrodes on the skin.	Uses ultrasound waves to generate detailed images of the heart.
Procedure	Electrodes are placed on the chest, arms, and legs to record electrical signals.	A gel is applied to the chest, and a transducer is used to create images of the heart.
Duration	Typically lasts 5-10 minutes.	Can take 30-60 minutes, depending on the type of echocardiogram.
Purpose of Use	Detects arrhythmias, heart attacks, and other electrical issues.	Evaluates heart chambers, valves, and blood flow. Identifies structural problems.
Invasiveness	Non-invasive and quick.	Non-invasive, but requires a gel application for imaging.
Key Output	Shows electrical signals of the heart as waves.	Produces images of the heart’s structure and motion.
Common Uses	Detects heart rate abnormalities, arrhythmias, and heart damage.	Assesses heart size, valve function, and blood flow; identifies heart disease or defects.
Risk	Very low risk, some skin irritation possible.	Very low risk, no radiation, but may cause discomfort from the gel or pressure of the transducer.
