text: Yo, check it out, let me break it down
  82 patients, mediastinoscopy in town
  Atrial detector electrode, permanent pacing
  No complications, that's what we're facing
  
  80 patients, P wave recorded fine
  But during the week, things started to decline
  P wave became ineffective, causing a fuss
  Angina in two, atrial arrhythmias, what a rush
  
  Atrial triggered ventricular pacing, the solution's here
  Established in 73 patients, let's make it clear
  71 patients followed for months, 1 to 113
  But in 17 cases, it had to end, it seems
  
  Ineffective or unstable P wave, that's why
  Six cases had atrial arrhythmias, oh my
  Four cases were due to age and infections' reign
  But yo, the method's simple, causing little strain
  
  Technically simple, stress on the low
  This procedure's smooth, just so you know
