What is the significance of the equipotentia I lines in EC G? They are used for medication dosage They show istribution during depolarization They indicate blood flow They measure heart rate
Jawaban
Here's why:
* Electrocardiogram (ECG): An ECG records the electrical activity of the heart.
* Depolarization: The process where the heart muscle cells become electrically charged, causing contraction.
* Equipotential Lines: Lines on an ECG map that connect points of equal electrical potential.
How Equipotential Lines Work:
* When the heart depolarizes, the electrical potential changes across the heart muscle.
* Equipotential lines connect points with the same electrical potential at a specific moment in time.
* By analyzing the pattern of these lines, we can understand how the electrical activity spreads through the heart.
Significance:
* Normal Heart Function: Equipotential lines help identify normal patterns of electrical activity, indicating a healthy heart.
* Abnormal Heart Function: Deviations in the equipotential lines can indicate problems like:
* Arrhythmias: Irregular heartbeats
* Myocardial Infarction (Heart Attack): Damage to heart muscle
* Conduction Defects: Problems with the electrical pathways in the heart
Other Options:
* Medication Dosage: ECG is not directly used for determining medication dosage.
* Blood Flow: ECG primarily measures electrical activity, not blood flow.
* Heart Rate: While ECG can measure heart rate, equipotential lines are more focused on the spread of electrical activity.
