The news wires for atrial fibrillation were abuzz this last week. The vigor and speed with which health news travels is striking.
Since 2.6 million Americans live with AF, my guess is that many are looking at the release of the Medtronic-sponsored TTOP-AF trial with anticipation. Here is a link to the press release. The trial purported to show benefits of Medtronic’s novel phased RF ablation system in treating persistent AF.
The study was small and released at a relatively small symposium in Venice, Italy. The TTOP-AF trial randomized 210 patients with persistent AF (including flutter) to either ablation with Medtronic’s ablation system or conventional therapy with drugs and cardioversions.
They found, not surprisingly, that AF ablation reduced AF burden. AF ablation significantly reduced AF burden in 55.8% percent of patients versus only 26% of those treated with conventional medical treatment. Editorial comment: That kind of data is pretty typical.

It may seem a little formal to say this, but I would like to start by stating my goals for today’s post:
- Introduce the concept of the athletic heart;
- Touch upon the notion of sudden death of the athlete;
- Explain what an ECG really is, and how it may help diagnose heart disease;
- Review a recent study about the common ECG variant seen in athletes…Early repolarization.
Intro: The adaptations of the human heart never cease to amaze me. Physical training transforms our hearts into high performance engines. Repeated sessions of interval training, combined with longer aerobic efforts, and sprinkled with adequate rest maximize our ability to keep pressure on the pedals, or run the sixth mile of the 10k at the same pace as the first, or for you swimmers, to keep getting back to the wall on the 1:15 mark.
Fitness also brings measurable changes in things we can observe. Read more »

Belgian researchers from the European nanoelectronics and nano-technology research center Imec, Holst Centre, and Katholieke Universiteit in Leuven developed an EEG based writing system that may be helpful for people with severe disabilities.
The Mind Speller, though, seems very similar to University of Wisconsin-Madison’s communication tool we wrote about a year ago that flashes rows and columns of characters and monitors when the brain notices the character it wants to type.
It detects and interprets P300 event-related potentials in the EEG-signals of a person that is selecting characters from a display presenting alternate rows and columns of characters. P300 potentials are often used as metrics of cognitive function in decision making processes. However, currently available P300 devices are large, expensive and uncomfortable in use. Read more »
