family history (someone in family defo has it)
Optimal management of Marfan syndrome
echo
beta blockers
angiotensin II receptor blockers
aortic surgery
3 Marfan-like syndromes

romano ward syndrome
the most common form of long QT syndrome
romano ward symptoms
syncope
‘seizure’
sudden death
romano ward causes can be
emotion
drugs
exercise
romano ward ECG will show a
prolonged QT interval
depolarisation anomalies
Brugada syndrome ECG is
prolonged PR interval
usually results in sudden cardiac death
Hypertrophic cardiomyopathy prevalence is
1 in 500
Hypertrophic cardiomyopathy
myocardium is abnormally thick
can sometimes have abnormal sarcomere
