ECG
An ECG (Electrocardiogram) is a medical test that measures the electrical activity of the heart to assess its function and detect potential abnormalities. The test records electrical signals as the heart beats and displays them as waveforms on a monitor or paper. These waveforms help doctors evaluate heart rhythm and identify conditions affecting the heart.
Key Aspects of an ECG:
- Heart Rhythm Assessment: Determines whether the heart is beating normally or if there are arrhythmias (irregular heartbeats).
- Heart Rate: Measures how fast the heart is beating (normal, fast, or slow).
- Electrical Activity: Assesses how electrical impulses move through the heart, detecting issues like blocked or slowed pathways.
- Heart Attacks: Identifies signs of a previous or ongoing heart attack.
- Ischemia: Detects reduced blood flow to the heart muscle.
- Structural Issues: Helps diagnose heart enlargement or thickened heart muscles.
Electrolyte Imbalances: Shows abnormal levels of potassium, calcium, or other electrolytes affecting heart function.
