On rounds one day I was presented a case of a elderly gentlemen with chest pain who had a episode of a life threatening heart rhythm disturbance “VFIB/VTACH" while being transported by the Ambulance Service to the Hospital.
The Paramedic’s notes said the patients vital signs were stable with a BP of 136/74. The notes also said he looked remarkably well during this rhythm disturbance. At the bedside the patient told us they had taken a especially rough and bumpy road to the hospital.
Looking at the rhythm strip I notice normal sinus rhythm followed by wide undulating complexes that return to sinus rhythm. The Heart tracing spikes or QRS complexes marched out unchanged so I concluded that this was artifact caused by the ambulance going over a rough patch of road or a speed bump.
Speed bumps in New Zealand are called judder bars. So I explained the house staff that this was judder bar artifact. One of my colleagues suggested I write this up and call it "Judder Bar Flutter". So this is the world premiere of a new rhythm first described by Stephen Stowers MD FACC Senior Consultant in Cardiology Palmerston North Hospital. Cheers from Palmy on the North Island of New Zealand!

ReplyDeleteThe judder bar flutter discussion demonstrates how little design errors can result in unexpectedly significant annoyances. As an illustration, resume writers may be able to relate to how a small misalignment throws off the flow, serving as a reminder that accuracy is crucial. Everyone's everyday experience and safety can be enhanced by carefully addressing these problems.
