What is the purpose of the standard limb lead in ECG? To analyze muscle activity To provide a minimum standard for electrodes To measure blood pressure To record temperature
Jawaban
* Standard limb leads in an electrocardiogram (ECG) are used to create a 12-lead ECG. These leads are placed on the limbs (arms and legs) to record electrical activity of the heart from different angles.
* The purpose of these leads is to standardize the placement of electrodes, ensuring consistency across different patients and healthcare providers. This standardization allows for accurate interpretation of the ECG.
Let's look at why the other options are incorrect:
* To analyze muscle activity: While muscles do have electrical activity, ECGs are specifically designed to measure the electrical activity of the heart.
* To measure blood pressure: Blood pressure is measured using a sphygmomanometer, not an ECG.
* To record temperature: Temperature is measured using a thermometer, not an ECG.
