An ECG (electrocardiogram) shows how fast the heart is beating, the rhythm of the heart beats (steady or irregular), and the timing of the electrical impulses as they move through the different parts of the heart. Changes in an ECG can indicate various heart-related conditions.
In more detail, an ECG provides a visual representation of the heart's electrical activity, helping doctors assess its function.
Key Aspects Shown by an ECG:
- Heart Rate: The ECG determines the number of heartbeats per minute.
- Heart Rhythm: It identifies any irregularities in the heart's rhythm, such as arrhythmias.
- Electrical Impulse Timing: The ECG tracks how electrical signals travel through the heart, revealing potential blockages or delays.
Specific Heart Conditions Detectable by ECG Changes:
An ECG can help detect a range of heart conditions. For example:
- Arrhythmias: Irregular heartbeats.
- Ischemia: Reduced blood flow to the heart muscle.
- Heart Attack: Evidence of damage to the heart muscle.
- Cardiomyopathy: Enlarged or thickened heart muscle.
Therefore, an ECG is a valuable tool for evaluating heart health and diagnosing various cardiac conditions.
