What is Electrocardiogram (ECG)?
Electrocardiogram is a vital diagnostic tool used in the field of cardiology to evaluate the electrical activity of the heart. It is a non-invasive procedure that helps in detecting various cardiac abnormalities and monitoring the heart’s health.How ECG is done?
It is done by placing electrodes on the skin, which detect the electrical signals produced by the heart as it beats. These signals are then recorded and analyzed by a machine, providing valuable information about the heart’s electrical activity and rhythm.What is three types of Electrocardiogram?
Resting ECG:
A resting electrocardiogram is perform while the patient is at rest and is commonly used as a screening tool for assessing overall heart health.
Stress ECG
A stress Electrocardiogram, also known as a treadmill test, is conduct while the patient exercises on a treadmill or stationary bike. It helps in evaluating the heart’s response to physical exertion and is often use to diagnose coronary artery disease.
Holter Monitoring
Holter monitoring involves wearing a portable device for an extend period, typically 24 to 48 hours, to record the heart’s electrical activity during normal daily activities. It is useful for detecting intermittent arrhythmias and evaluating the effectiveness of anti-arrhythmic medications.

What is the principle of Electrocardiogram?
The principle of ECG involves detecting and recording the electrical signals generate by the heart as it beats. Electrodes place on the skin pick up these signals, which are then amplifies and display as a graphical representation of the heart’s electrical activity over time. This helps in assessing the heart’s rhythm, detecting abnormalities, and diagnosing cardiac conditions. What is an electrocardiogram used to diagnose ? 1. Arrhythmias (irregular heart rhythms) 2. Myocardial infarction (heart attack) 3. Atrial fibrillation 4. Heart valve disorders 5. Cardiac hypertrophy (enlargement of the heart) 6. Conduction abnormalitiesCan ECG detect heart attack?
Yes, this test can detect a heart attack. It can identify specific patterns of electrical activity in the heart that indicate myocardial infarction (heart attack). This is crucial for prompt diagnosis and treatment of a heart attack, as it allows healthcare providers to intervene quickly to minimize damage to the heart muscle.
What is normal ECG report ?
| Component | Normal Range/Description |
|---|---|
| Heart Rate | 60-100 beats per minute (bpm) |
| P Wave | Present, consistent in shape and duration |
| PR Interval | 0.12 to 0.20 seconds (3-5 small squares) |
| QRS Complex | 0.06 to 0.10 seconds (less than 3 small squares) |
| QT Interval | Varies with heart rate, corrected QT interval (QTc) less than 0.44 seconds |
| T Wave | Present, consistent in shape |
| Rhythm | Regular and consistent |
| Axis | Within normal range (-30° to +90°) |
| ST Segment | Isoelectric (at baseline), no elevation or depression |
| T Wave Inversion | Absent or insignificant |
