Q

What is the purpose of the P wave in an EKG?

A

It represents atrial depolarization.

17
Q

Which part of the EKG waveform corresponds to ventricular depolarization?

A

QRS complex

18
Q

True or False: The T wave represents ventricular repolarization.

A

True

19
Q

What is the normal heart rate range indicated by an EKG?

A

60 to 100 beats per minute

20
Q

Multiple choice: Which lead is typically used as the reference lead in a standard EKG?

A

Lead II

21
Q

What does the ST segment indicate in an EKG?

A

It indicates the period between ventricular depolarization and repolarization.

22
Q

True or False: An EKG can diagnose heart conditions.

A

True

23
Q

Fill in the blank: The interval that measures the time between the start of the P wave and the start of the QRS complex is called the _____ interval.

A

PR

24
Q

What is the significance of a prolonged QT interval?

A

It can increase the risk of arrhythmias.

25
Q

Multiple choice: What does a flat T wave potentially indicate?

A

Myocardial ischemia

26
Q

What is the role of electrodes in an EKG?

A

They detect the electrical signals from the heart.

27
Q

True or False: EKGs can only be performed in a hospital setting.

A

False

28
Q

Fill in the blank: The _____ wave reflects atrial contraction.

A

P

29
Q

What can cause artifacts in an EKG reading?

A

Patient movement, poor electrode placement, and electrical interference.

30
Q

Multiple choice: Which of the following conditions can be diagnosed with an EKG?

A

Arrhythmias

31
Q

What does the U wave represent in an EKG?

A

It is thought to represent repolarization of the Purkinje fibers.

32
Q

True or False: EKGs can be used to monitor heart function over time.

A

True

33
Q

Fill in the blank: The _____ interval measures the time it takes for the ventricles to depolarize and repolarize.

A

QT

34
Q

What is the significance of the heart’s electrical axis in EKG interpretation?

A

It helps determine the direction of the heart’s electrical activity.

35
Q

What might an elevated ST segment indicate?

A

Myocardial infarction

36
Q

Multiple choice: Which EKG finding is characteristic of atrial fibrillation?

A

Irregularly irregular rhythm

37
Q

True or False: A resting EKG can show signs of a previous heart attack.

A

True

38
Q

What is the main advantage of a 12-lead EKG over a single-lead EKG?

A

It provides a comprehensive view of the heart’s electrical activity from multiple angles.
