Final answer:
The correct placement for ECG leads is: Right Arm on the right upper chest, Left Arm on the left upper chest, and Left Leg on the left lower abdomen. This arrangement allows for accurate recording of the heart's electrical activity, which is essential for diagnosing heart conditions.
Step-by-step explanation:
The correct electrode placement for each of the leads in a standard 12-lead electrocardiogram (ECG) consists of ten electrodes placed on the patient's body. Six electrodes are placed on the chest, known as the precordial leads V1 through V6, and four electrodes are placed on the limbs. The limb electrodes consist of:
- Right arm (RA): placed on the right upper chest.
- Left arm (LA): placed on the left upper chest.
- Left leg (LL): placed on the left lower abdomen.
- Right leg (RL): typically used as a ground and placed on the right lower abdomen.
Thus, the correct option for the electrode placement among the given choices is:
D) Right Arm: Right Upper Chest, Left Arm: Left Upper Chest, Left Leg: Left Lower Abdomen
An ECG is a vital diagnostic tool that records the heart's electrical activity using these electrodes. Understanding the proper placement of ECG leads is essential for accurate reading and interpretation of the heart's electrical signals, identifying areas of damaged heart tissue, and diagnosing various cardiac conditions.
