Question

Which of the following is false about ECG?

• A. P wave $\to$ artial depolarisation
• B. QRS complex $\to$ ventricular depolarisation
• C. T wave $\to$ ventricular repolarisation
• D. ST depression indicates infarction

Answer 1

The correct option is D

ST depression indicates infarction

The ST segment is the flat, isoelectric section of the ECG between the end of the S wave (the J point) and the beginning of the T wave. It represents the interval between ventricular depolarization and repolarization.
