Q

ECG Findings for subendocardial ischaemia

A
31
Q

What is digitalis effect

A

From Taking too much Digoxin
Has a curved ST segment

32
Q

What is an NSTEMI

A

Non-ST elevation myocardial infarction

33
Q

ECG findings for a Transmural Infarction

A

Can also get a pathological Q-wave (>2mm deep + >0.04ms wide)

34
Q

Pathological Q waves and Infarct Locations

A

Septal Wall: V1,V2
Anterior Wall: V3,V4
Anterolateral: V3-V6, I, aVL
Subendocardial - None

aVR is not a reliable lead for diagnosing patological Q wave

35
Q

Other causes of Pathological Q-waves

A

Bundle Branch Block, Wolff-Parkinson-White Syndrome

36
Q

Table to describe subendocardial vs Transmural

A
37
Q

What is considered a patholoigcal sign of ischaemia

A

T wave inversion leads V2-V6

38
Q

____ conduction through the atrioventricular node ensures that ventricles have enough time to fill with blood before contracting.

A

Slow

39
Q

Decreased ventricular filling can result from an

A

increase in conduction velocity at the atrioventricular node.

40
Q

Increases in conduction velocity at the atrioventricular node can lead to

A

decreased stroke volume.

41
Q

The resting membrane potential of cardiac cells is primarily determined by

A

potassium ions.

42
Q

Conduction velocity in the heart is slowest at the

A

AV node

43
Q

Conduction velocity in the heart is fastest at the

A

Purkinje fibers

44
Q

_____ in the ECG corresponds to the atrial depolarization.

A

P wave

45
Q

P wave in the ECG corresponds to the

A

atrial depolarization

46
Q

The PR-interval in the ECG is the

A

time from start of atrial depolarization to start of ventricular depolarization (normally <200 msec).

47
Q

The QRS complex in the ECG corresponds to

A

electrical ventricular depolarization (normally < 120 msec).

48
Q

ECG corresponds to the mechanical contraction of the ventricles

A

QT interval

49
Q

ECG corresponds to ventricular repolarization

A

T wave

50
Q

J point of the ECG corresponds to the

A

junction between the end of QRS-complex and the start of ST-segment.

51
Q

The U wave of the ECG is prominent in

A

hypokalemia and bradycardia.

52
Q

The lateral leads of the electrocardiogram are leads

A

I, aVL, V5, and V6.

53
Q

The inferior leads of the electrocardiogram are leads

A

II, III, and AVF

54
Q

Normally, the R wave is larger than the S wave in

A

lead V4 on electrocardiogram.

55
Q

The QRS transition zone is usually seen in the chest leads

A

V3 and V4.

56
Q

QRS transition zone will shift towards a region of

A

hypertrophy

57
Q

Angina caused by vasospasm, or Prinzmetal’s angina, can cause transient in the absence of an infarction.

A

ST elevation

58
Q

Ventricular aneurysm can cause persistent

A

ST elevation in most of the chest leads on electrocardiogram.

59
Q

_______ causes diffuse ST elevation.

A

Pericarditis

60
Q

Significant Q waves on electrocardiogram indicate

A

necrosis and are diagnostic of infarction.

61
Q

A large R wave in lead V1 or V2 of electrocardiogram should raise suspicion for a

A

posterior infarction

62
Q

ST segment depression in the right chest leads of electrocardiogram should raise suspicion for an

A

acute posterior infarction.
