Amir Sam Flashcards
Structure to HPC
Ask about presenting symptoms- socrates
Associated symptoms to that system
Then questions relating to your differential diagnoses
Associated symptoms with MI
Nausea
Sweating
Breathlessness
Chest pain investigations
ECG
Troponin
Echo
DDx of chest pain
Cardiac - IHD - aortic dissection - pericarditis Resp - PE -Pneumothorax -Pneumonia GI - oesophagitis - gastritis - oesophageal spasm Musculoskeletal - costochondritis
Important investigation forgotten about in chest pain
BP both arms to check for aortic dissection
Anterior MI ecg
LAD
V1-V4
Lateral MI ecg
Circumflex
V5-6
aVL
Inferior MI ecg
Right coronary artery
II, III
avF
Which enzymes get elevated acutely MI
CK isoform
What happens in seizure cause of collapse after event
Confused
Important thing to ask to ask about in family history with collapse
Sudden death in family
How to check for postural hypotension collapse
Change in BP lying vs standing
DDx collpase
Glucose Cardiac - valves - arrythmia - outflow obstruction - postural hypotension Neurological
Forgotten cause of outflow obstruction
PE
Investigations for cardiac causes
ECG
Pulse, ESM, echo
Lying and standing BP
What is long QT syndrome
Abnormal ventricular repolarisation
Acquired causes of long QT
Low K+, Mg+, Ca+, hypothermia
MI
Raised ICP
Drugs
Genetic cause of Long QT
Change in K+ channel
Family history sign of long QT
Sudden death
Cardiac causes of collapse
Reduced outflow
Arrythmia either brady or tachy
Postural hypotension
Vasovagal
What does long QT syndrome predispose you to
Tachyarrythmias
What does murmur louder on inspiration say about murmur
Murmur on right side
What are signs on examination of tricuspid regurg
Hepatomegaly
DDx of JVP
R heart failure
Tricuspid regurg
Constrictive pericarditis
Causes of JVP
R HF - pulmonary HTN -PE, COPD - secondary to left failure Tricuspid regurg - R ventricle dilation - vegetations - hepatomegaly Constrictive pericarditis - infection TB - autoimmune sarcoid - maligancy
Questions to ask self about murmur
Where loudest
Where radiate
DDx of sinus tachycardia
Caffeine Alcohol Sepsis Hypovolaemia Endocrine Anxiety
DDx of SVT
Re-entry circuit
Difference between AVNRT and AVRT
AVNRT at level of node
AVRT goes into ventricles and back up bundle of kent
Is there an upstroke in AVNRT
No
AVRT on ECG
SR
Short PR interval
Delta wave
Causes of AF
Thyrotoxicosis
Alcohol
Heart- muscle, valve, pericardium
Lung- PE, pneumonia, Cancer
Causes of VT
Iscaemia
Electrolyte
Long QT
Drugs
Managment of haemodynamically stable SVT
- Valsalva
2. adenosine
Acute fast AF management
Rythm and rate control
Causes and complications
Categories of ECG abnormaliites
Iscaemia
Arrythmia or block
Vent strain or hypertrophy
What causes third heart sound
Associated with ventricular filling- very common in HF
