Cardiology MCQ: a and v waves

False statement regarding ‘a’ and ‘v’ waves in atrial pressure tracing: a) Right atrial ‘a’ wave is taller than ‘v’ wave b) Left atrial ‘v’ is taller than ‘a’ wave c) In atrial septal defect ‘a’ and ‘v’ waves are equal d) None of the above Correct answer: d) None of the above Normally ‘a’ wave is taller in the right atrium and ‘v’ wave is taller in the left atrium [1]. In atrial septal defect, ‘a’ and ‘v’ waves are equal due to equalization of atrial pressures by the large unrestricted communication [2]. References Eric J. Topol, Robert M. Califf, Eric N.
