Which component of the ECG represents ventricular depolarization?

QRS complex

Explanation

Represents ventricular depolarization.

What does the term 'QT interval' represent in an ECG?

Ventricular repolarization time

Explanation

Represents ventricular repolarization time.

What does the term 'sinus rhythm' refer to in an ECG?

Normal heart rhythm

Explanation

Refers to normal heart rhythm.

Which part of the ECG represents atrial repolarization?

T wave

Explanation

Represents atrial repolarization.

What does the term 'premature ventricular contraction (PVC)' indicate in an ECG?

Early heartbeat originating in the ventricles

Explanation

Indicates early heartbeat originating in the ventricles.

What does a prolonged PR interval on an ECG indicate?

Heart block

Explanation

Indicates heart block.

In ECG nomenclature, what does the term 'ST segment' stand for?

Systolic time

Explanation

Represents systolic time.

In ECG, what is the primary purpose of the 'T wave'?

Ventricular repolarization

Explanation

Indicates ventricular repolarization.

Which condition is associated with a 'flat' or 'inverted' T wave in an ECG?

Hypokalemia

Explanation

Associated with hypokalemia.

#10

Which ECG lead provides information about the lateral wall of the heart?

Lead aVL

Explanation

Provides information about the lateral wall.

#11

What does the presence of 'sawtooth' pattern in an ECG suggest?

Atrial fibrillation

Explanation

Suggests atrial fibrillation.

#12

Which lead in the standard 12-lead ECG provides information about the inferior wall of the heart?

Lead III

Explanation

Provides information about the inferior wall.

#13

What is the standard paper speed used in most ECG recordings?

50 mm/s

Explanation

Standard paper speed is 50 mm/s.

#14

In lead aVL of the standard 12-lead ECG, which area of the heart is predominantly viewed?

Lateral wall

Explanation

Predominantly views the lateral wall.

#15

Which condition is characterized by a rapid, irregular atrial rhythm on an ECG?

Atrial fibrillation

Explanation

Characterized by rapid, irregular atrial rhythm.
