Q

the reference level for measuring ST-segment deviation (depression or elevation)

A
  • is not the TP interval
  • correct reference level is the PR segment
  • this level is also called baseline level or isoelectric level

27
Q

the P-wave reflects

A

atrial depolarization (activation)

28
Q

the PR interval is the distance ____

A

between the onset of the P-wave to the onset of the QRS complex

29
Q

why is the PR interval assessed

A

in order to determine whether impulse conduction from the atria to the ventricles is normal

30
Q

the flat line between the end of the P-wave and the onset of the QRS complex is called

A

the PR segment and it reflects the slow impulse conduction through the atrioventricular node

31
Q

the QRS complex represents ____

A

the depolarization (activation) of the ventricles

32
Q

QRS duration is the _____

A

time interval from the onset to the end of the QRS complex

33
Q

a _____ QRS complex is desirable as it proves that the ventricles are depolarized rapidly which in turn implies that the conduction system functions properly

A

short

34
Q

_____ QRS complexes indicate that ventricular depolarization is show, which may be due to dysfunction in the conduction system

A

wide (also referred to as broad)

35
Q

the ST segment corresponds to the _____ of the action potential

A

plateau (phase 2)

36
Q

the ____ is of particular interest in the setting of acute myocardial ischemia because ischemia causes deviation of the _______

A

ST segment

37
Q

what are the 2 types of ST segment deviations

A
  • ST segment depression: implies that the ST segment is displaced such that it is below the level of the PR segment
  • ST segment elevation: implies that the ST segment is displaced such that it is above the level of the PR segment
38
Q

the T wave reflects _____

A

the rapid depolarization of contractile cells (phase 3) and T-wave changes occur in a wide range of conditions

39
Q

the normal T-wave is slightly _____ with a steeper downward slope

A

asymmetric

40
Q

the U-wave is a

A

positive wave occurring after the T-wave

41
Q

the U-wave is most frequently seen in leads ____

A

V2-V4

42
Q

Individuals with prominent T-waves, as well as those with slow heart rates display ____ more often

A

U-waves

43
Q

reflects the total duration of ventricular depolarization and repolarization

A

QT duration

44
Q

____ is measured from the onset of the QRS complex to the end of the T-wave

A

QT duration

45
Q

the heart rate adjusted QT interval is referred to as the ____

A

corrected QT interval (QTc interval)

46
Q

a ____ QTc interval increases the risk of ventricular arrhythmias

A

long

47
Q

the ____ is a small, positive and smooth wave

A

P-wave
