Definition of Electrocardiogram (ECG):
The electrical activity of the heart is monitored and documented by an electrocardiogram (ECG). It detects any irregularities in the heart's rhythm and is thus used to investigate and detect heart disease such as heart enlargement, heart inflammation, and coronary heart disease.
ECGs from healthy hearts have a distinct shape. Any observed irregularity alters the electrical activity of the heart, changing the shape of the ECG.
What exactly is an electrocardiogram (ecg) laboratory test?
The Electrocardiogram (ECG/EKG) Lab Test is recommended by the doctor when he wants to study the heart and determine if the person has any heart-related disease. Small electrode patches were applied to the skin of the chest, arms, and legs by a lab technician. These electrode patches aid in the recording of the heart's electrical activity.
The ECG test is quick, painless, and safe. This test aids the doctor in the diagnosis of the following conditions:
• Recognize a heart attack
• Check to see if there is any abnormal blood flow to the heart (this is called ischemia)
• Examine the heart rhythm.
• Examine anything that appears to be abnormal in terms of the heart.
An ECG test cannot determine whether or not the heart is blocked, nor can it predict whether or not a heart attack will occur in the future. Furthermore, it is critical to understand the distinction between a resting ECG and a cardiac imaging test, exercise ECG, or stress ECG.
There is no need for this test as part of routine checks if there are no high-risk factors for heart disease, such as high blood pressure or other symptoms of heart disease. Even so, many people have the ECG test as part of their regular check-ups, which is unnecessary. Though the ECG is not harmful, it may cause unnecessary anxiety due to an irregular heartbeat.
