- ECG (Electrocardiogram) is a test that records the electrical activity of the heart and helps doctors know if the heart is beating normally or if there are problems like irregular heartbeat or heart attack.
- It is quick, painless, and done by placing small stickers (electrodes) on the chest, arms, and legs, which are connected to a machine that draws a line graph showing the heart’s rhythm.
- Doctors use ECG to check chest pain, dizziness, shortness of breath, or as part of a routine checkup for heart health, especially for people with high blood pressure, diabetes, or a family history of heart disease.
🧠 Explanation:
ECG is associated with the heart, measuring its electrical activity. Knowing this helps students and health enthusiasts understand medical diagnostics. ECG is key for studying biology or medicine in school. Learning this helps with science projects or exploring health monitoring. It’s useful for biology classes, making it relevant for understanding heart health. Knowing ECG’s purpose helps students grasp its importance, ensuring better comprehension for academic work or general knowledge about medical technology.
