A 47 year old man with history of IHD complains of chest pain with SOB on exertion over the past few days

A 47 year old man with history of IHD complains of chest pain with SOB on exertion over the
past few days. ECG normal, Echo= increased EF (ejection fraction) and decreased septal wall
thickness. What is the most likely diagnosis?

  • a. Dilated CM
  • b. Constrictive pericarditis
  • c. Amyloidosis
  • d. Subacute endocarditis

Ans. The key is A. Dilated CM. [In dilated cardiomyopathy ejection fraction is decreased (but here
increased which goes in favour of constrictive pericarditis). On the other hand decreased septal wall
thickness favours the diagnosis of dilated cardiomyopathy. So it seems to be a bad recall!!].

ECG of an 80 year old patient of ICH shows saw-tooth like waves, QRS complex of 80ms
duration, ventricular rate=150/min and regular R-R interval. What is the most porbable
diagnosis?

  • a. Atrial fib
  • b. Atrial flutter
  • c. SVT
  • d. Mobitz type1 second degree heart block
  • e. Sinus tachycardia

Ans. The key is B. Atrial flutter. [Saw-tooth like waves, normal QRS complex of 80 ms (normal range 70-100 ms), ventricular rate of 150/min and regular R-R interval is diagnostic of atrial flutter].
