"Normal ECG" refers to an electrocardiogram (ECG) that shows a regular heart rhythm and electrical activity, indicating that the heart is functioning properly. The ECG traces display consistent wave patterns, such as the P wave, QRS complex, and T wave, all of which fall within the expected ranges for duration, amplitude, and morphology. A normal ECG suggests that the heart's electrical impulses are being generated and conducted effectively, which is a sign of healthy heart function.
On the other hand, an "Abnormal ECG" indicates that the heart's electrical activity is irregular or deviates from the norm, potentially signaling underlying heart conditions. Abnormalities can manifest in various forms, such as irregular heartbeats (arrhythmias), changes in the size or shape of the heart's chambers, or evidence of heart muscle damage, as seen in conditions like ischemia or myocardial infarction. An abnormal ECG may prompt further medical evaluation to determine the specific cause and to assess the need for treatment. Understanding the distinction between normal and abnormal ECG results is crucial for diagnosing and managing cardiovascular health.
