Q

How is the apex beat assessed?

A
  • To palpate for the apex beat you should first locate the 2nd rib by finding the sternal angle as they are on the same level
  • Afterwards, you should count down to the 5th intercostal space on the left and move laterally to the mid-clavicular line
  • Once you have done so you should start to feel for the apex beat laterally and move more medially in case the apex beat is displaced
    • The apex beat is non-palpable in many patients but you can ask the patient to lean towards their left side, which may help you to feel it
    • You can also get the patient to jog on the spot for 1 minute to increase their heart rate but this would waste valuable time during the exam

Q

How are thrills assessed?

A
  • Thrills are felt in the same areas as the points of auscultation across all 4 valves as they are just palpable murmurs
  • To feel for them instead place your hand horizontally with your fingers more than the rest of your hand as they are more sensitive to the vibrations

Q

What is the clinical significance of heaves?

A
  • The main causes of heaves are hypertrophy of the left or right ventricle depending on where you feel the heaves due to there being more muscle to push against the anterior chest wall

Q

What is sinus bradycardia? What are the possible causes (2)?

A
  • ECG appearance:
    • Each P wave is followed by a QRS complex (1:1)
    • Rate is regular (even R-R intervals) and slow (
  • Causes:
    • Vagal stimulation
    • Muscular heart (reduced heart rate to maintain same cardiac output)

Q

What is sinus tachycardia? What are the possible causes (1)?

A
  • ECG appearance:
    • Each P wave is followed by a QRS complex (1:1)
    • Rate is regular (even R-R intervals), and fast (>107bpm)
  • Causes:
    • Often physiological response (i.e. secondary)

Q

What is sinus arrhytmia?

A
  • ECG appearance:
    • Each P wave is followed by a QRS wave
    • Rate is irregular (variable R-R intervals), and normal (65-100bpm)
    • R-R intervals varies with breathing cycle
31
Q

What is atrial fibrillation? What are the physiological risks of atrial fibrillation?

A
  • ECG appearance:
    • Oscillating baseline given the atria are contracting asynchronously
    • The rhythm can be irregular and rate may be slow
  • Physiological risk:
    • Turbulent flow pattern increases clot risk
32
Q

What is atrial flutter?

A
  • ECG appearance:
    • Regular saw-tooth pattern in baseline (leads II, III, and AVF)
    • Atrial:ventricular beats (2:1 ratio or 3:1 ratio)
    • There are P waves without succeeding QRS complexes
33
Q

What is first degree heart block?

A
  • ECG appearance:
    • The PR segment is inappropriately long, there is impaired conduction through the atrioventricular node to the ventricles
      • Prolongation is caused by slower AV conduction
    • There is a regular rhythm, 1:1 ratio of P waves to QRS complexes
34
Q

What is a Mobitz - I (Second degree) heart block?

A
  • ECG appearance:
    • Progressive prolongation of the PR interval until a beat is dropped
    • Majority of P waves are followed by QRS complex
    • Regularly irregular rhythm, caused by diseased AV node (i.e. 75 75 40 75 75 40)
35
Q

What is a Mobitz - II (Second degree) heart block?

A
  • ECG appearance:
    • P waves are regular, however only some are followed by QRS complex
    • There is NO PR prolongation
    • Regularly irregular rhythm
36
Q

What is third degree heart block?

A
  • ECG appearance:
    • P waves are regular, QRS are regular however there is no relationship
    • Truly non-sinus rhythmn
      • ​There is complete AV nodal failure
37
Q

What is ventricular tachycardia? How is it managed?

A
  • ECG appearance:
    • P waves are hidden, given that there is dissociated atrial rhythm
    • Rate is regular and fast (100-200bpm)
  • Management:
    • Shockable rhythm
38
Q

What is ventricular fibrillation? What is its physiological effect?

A
  • ECG appearance:
    • Rhythm is irregular and >250bpm
    • Uncoordinated manner, the QRS complexes are irregular, thus there is no coordination of muscular contraction
  • Physiological effects:
    • Unstable to generate cardiac output
39
Q

What causes ST elevation? By what measurement is ST elevation classified?

A
  • Infarction (tissue death caused by hypoperfusion)
