SpletWe at CardioServ, suggest using both TAPSE and S’ Wave. If you are only limited to one, S’ Wave is easily obtained and more reproducible. If you do get an abnormal S’ Wave, it would be idea to also perform a TAPSE as an additional method to proving your abnormal value. SpletNot to belittle anyone, but to understand what an rSR’ is, we first need to know the components of the QRS complex. Q-wave: The first downward deflection before the R-wave. R-wave: The first upward deflection of a QRS complex. S-wave: The first downward deflection after the R-wave.
