Jonas Gustavsson Syndrome

A few months ago the Leaf’s new goaltender underwent two rounds of treatment for a “heart condition”. I was surprised to see his specific problem receive so little mention in the sports press. For you Toronto fans, of which I am not – Deeeeetroit, here is a look at what his heart condition was.

The monster’s condition was a cardiac arrythmia – a problem within the electrical conduction system of the heart. Most probably atrioventricular reentrant tachycardia (AVRT). AVRT is just a big scary medicalese acronym. I will explain first with an example of how a normal heart beat works.

Framework for thinking about tachycardia

Supraventricular tachycardia. AV non-nodal reentrant tachycardia. SV tachycardia with aberrancy such as a bundle branch block. Bundle who? Super what?

Tachycardia is guilty of committing the sin of medicalese. An overuse of lengthy latin and greek words which make the topic appear unattainable. I certainly felt this way until I came across references that view tachycardias through a system. Although there are a few of these resources that are great (i.e. Rob Theriault’s CDI) my personal favourite is Ed Wallit’s of PodMedics.

New international AED sign

ILCOR has announced an official international sign for automatic external defibrillators (AEDs). ILCOR chairman and cardiologist R.W. Koster described the sign as indicating the presence of an AED within a room, a container or that an AED can be found in a certain direction. The symbol purposefully has no markings to allow for international usage.

Increasingly research is indicating that the best patient outcomes do not require advanced life support (ALS), pharmacological treatment or invasive procedures. As Dr. John Burton describes, if you want to survive a heart attack out of hospital then you will want; Someone nearby to quickly begin CPR; An AED to be very close; And to have your core body temperature dropped a few degrees. Bringing AEDs closer to cardiac arrest is one of the simplest measures that can be undertaken to improve patient outcome.
