ECG is used for the diagnosis of ailments of?

An ECG, or Electrocardiogram, is a medical test used to record the electrical activity of the heart. It is one of the most common and essential diagnostic tools for detecting various heart-related ailments. The heart produces tiny electrical impulses with every heartbeat, which help it contract and pump blood throughout the body. An ECG machine detects these impulses using electrodes placed on the skin and displays them as a graph on paper or a monitor.

The main purpose of ECG is to help doctors:

• 
  

  Detect abnormal heart rhythms (arrhythmias).

  
  


• 
  

  Identify damage to the heart muscle caused by conditions like heart attacks (myocardial infarction).

  
  


• 
  

  Check for blockages in blood flow or heart enlargement.

  
  


• 
  

  Monitor the effectiveness of heart medications or medical devices such as pacemakers.

  
  

The test is simple, painless, and non-invasive. Small electrodes are attached to specific areas of the patient’s chest, arms, and legs. These sensors capture the heart’s electrical signals, which are then analyzed by healthcare professionals. The pattern of the ECG waveform helps in diagnosing various cardiac conditions.

Other options in the question are not correct:

• 
  

  Brain ailments are diagnosed with EEG (Electroencephalogram), not ECG.

  
  


• 
  

  Kidney diseases are tested using blood and urine analysis, not ECG.

  
  


• 
  

  Lung diseases are typically examined with chest X-rays, spirometry, or CT scans.

  
  

In conclusion, an ECG is specifically used for diagnosing diseases and abnormalities of the heart. It is a vital tool in cardiology to ensure proper heart function, detect early signs of heart problems, and guide treatment plans for patients with cardiovascular diseases.
