ECG
[iː siː dʒiː ]
Definition
medical device
An ECG, or electrocardiogram, is a medical test that records the electrical activity of the heart over a period of time. It is commonly used to diagnose heart conditions, monitor heart health, and assess heart rhythm. The test is non-invasive and provides important information about the heart's electrical system.
Synonyms
Examples of usage
- The doctor ordered an ECG to evaluate the patient's heart function.
- During the annual check-up, the nurse performed an ECG to screen for irregularities.
- The ECG results showed signs of a previous heart attack.

Interesting Facts
Historical Origins
- The first ECG was recorded in 1887 by Dutch physician Willem Einthoven, who is often called the 'father of electrocardiography'.
- Einthoven developed the string galvanometer, which was crucial for producing the first accurate ECG readings.
- The term 'electrocardiogram' combines Greek roots: 'electro' for electric, 'kardia' for heart, and 'gram' for a written record.
Science
- ECGs help identify irregular heartbeats, called arrhythmias, which can indicate serious health issues.
- The heart generates electrical signals through specialized cells that coordinate the heartbeat, shown visually on an ECG graph.
- By analyzing the ECG waves, medical professionals can determine the size of the heart chambers and the presence of any heart complications.
Technology
- Modern ECG machines can produce results in real-time, enhancing the speed of patient diagnosis.
- Wearable technology, such as smartwatches, has started to include ECG features to monitor heart health conveniently.
- Telemedicine has made it possible to interpret ECGs remotely, allowing healthcare providers to assess patients from afar.
Pop Culture
- In movies and TV shows, an ECG monitor's beeping sound is often used to create suspense, especially in hospital scenes.
- Several pop songs reference heartbeats metaphorically, linking emotional experiences to the physical act of the heart beating, and sometimes visualizing an ECG line.
Psychology
- Anxiety and stress can lead to noticeable changes in heart rhythm, which can be detected by an ECG.
- Research has shown that mindfulness and relaxation techniques can help stabilize heart rhythms, reflecting a connection between mind and body.
- Certain psychological conditions, like panic attacks, can cause temporary heart rhythm disturbances visible in an ECG.
Origin of 'ECG'
The term 'electrocardiogram' originates from the combination of several Greek roots. The prefix 'electro-' refers to electricity, derived from the Greek word 'ēlektron', meaning 'amber' (used in early experiments with static electricity). The word 'cardio' comes from the Greek term 'kardia', meaning 'heart'. Finally, the suffix '-gram' is used in medicine to indicate a recording or a picture and comes from the Greek word 'grapho', meaning 'to write'. The ECG technique was developed in the early 20th century. Dutch physician Willem Einthoven is credited with inventing the first practical ECG machine in 1903, which made it possible to visualize the electrical activity of the heart for the first time. This groundbreaking invention revolutionized cardiology and has since become an essential tool in both medical diagnosis and monitoring.
