Accessory Pathway Location
There are a number of algorithms that can be used to estimate the location of the accessory pathway (AP). Many of these algorithms can be found in smartphone apps, I use EP Mobile which contains the following algorithms:
- Arruda Algorithm
- Milstein Algorithm
- Modified Arruda Algorithm
You can find an overview of each of these algorithms at ECGpedia's WPW page.
What are you going to tell your patient ?
I've put some links here to various patient information resources for WPW, I have not vetted or reviewed all these links but have chosen those from government / institutional sites.
- Cleveland Clinic - WPW Information
- Better Health Channel (Victoria) - WPW Information
- Medline Plus - WPW Information
If there are other links you feel should be added please comment and I'll add them.
