text: Yo, listen up, I got a study to discuss
  Checkin' out them pulsed TDI variables, no fuss
  I'm talkin' 'bout isovolumic time interval and major wave duration
  In a group of healthy dogs, no deviation
  
  We took 45 adult dogs, healthy and strong
  Checked the septal mitral annulus all day long
  Pulsed TDI was the method, we went deep
  Measuring velocities, time intervals, and waves, no sleep
  
  Maximal systolic velocity, we found it mean
  6.92 ± 1.78 cm/sec, you know what I mean?
  Early diastolic velocity, Em, was on the scene
  6.58 ± 1.81 cm/sec, keepin' it clean
  
  Late diastolic velocity, that's the Am, hold tight
  5.10 ± 2.00 cm/sec, day and night
  Isovolumic contraction time, we measured it too
  53.61 ± 95.13 msec, that's what we knew
  
  Isovolumic relaxation time, IVRT, check the stats
  26.74 ± 57.24 msec, no time to relax
  Early diastolic mitral inflow velocity, the E to Em ratio
  10.94 ± 3.27, that's how we go
  
  Em to Am ratio, we had that too
  1.40 ± 0.40, just for you
  Amplitude and duration, they showed their relation
  Negative correlation, no hesitation
  
  Positive correlation between IVRT and Em/Am ratio, yo
  (p < 0.05), that's how the numbers flow
  These pulsed TDI parameters, let me explain
  They're the reference range for dogs, no strain
  
  So when it comes to canine myocardial dysfunction
  We got the knowledge, we got the junction
  Use these findings as your guide, no bluffin'
  That's how we roll, in the world of canine lovin'
