Q. To obtain a standard ECG, a patient is connected to the machine with three electrodes
A) One to each wrist and to left ankle
B) One to each ankle and the left wrist
C) One to each wrist and to the left chest region
D) One to each ankle and to the left chest region
Explanation
Electrocardiogram is the instrument used to record potential differences of heart muscles. To make an ECG recording, the patient lies quietly on his/her back on a table. Lead is placed on certain spots on the patient’s chest. It is generally performed with six leads placed over the heart and three leads placed at certain points (one on each upper arm and one below a knee is common).
