I was invited to write another article for EP Lab Digest, and while I got my copies of the print version a few weeks ago, the online version just came out. I apologize in advance for the trite bit at the end, but I was under time pressure and had a hard time figuring out how to wrap it up.

Mind-Mapping and Reference Digging – Time Frame
As I’ve noted in previous posts, as I read a paper, I underline relevant passages. I also circle references I’m interested in. The paper then goes into my “to-map” file.
I like to “map” papers when I’m feeling braindead — when I’m too tired or too mentally exhausted to do things requiring extensive thought. This consists of loading relevant details for a paper into a mind map and then looking up all of the references I found interesting and adding them to my Cite-U-Like library.
I am feeling a bit tired today, and I just finished mapping a paper. By my timer, it took about 55 minutes for an 8-page paper. This is a pretty substantial amount of time (about 6.875 min/page). However, it allows me to browse or search a complete list of the relevant facts from papers I’ve read. This is much, much faster than re-reading each paper, and much more powerful than trying to keep track of all of the salient details in my head. I haven’t timed how long it takes me to map a paper before, and I’m going to try to remember to do it more. I’d like to get an average pages/minute. Of course, the times will be longer for “interesting” papers and shorter for less-“interesting” papers.
What do you do to keep track of important information from papers you’ve read?
What is a Harvard Respirator?
I was reading a paper today about a study on dogs, and it mentioned that the dogs were ventilated with a “Harvard Respirator”. It was pretty easy to find a few pictures on Google Images, but I couldn’t find much other information. Apparently it’s just a veterinary ventilator made by Harvard Apparatus. In case you ever need to know. I thought perhaps it was a particular type of device, like a “Holter Monitor”.
You will find a lot of mentions of Harvard respirators on Google, and they are mostly quotes from scientific papers stating that they used a Harvard respirator. Go figure.
ADDENDUM: The very same paper also mentions the pacing rate they used to stimulate the dog’s heart. They don’t mention the normal heart rate for a (mongrel) dog. I looked it up and found it here. It’s between 60-160 beats/min for average-sized adult dogs. That’s a pretty wide range. I’d like to see a plot of heart rate compared to size in dogs.
Cardiac Electrophysiology Basics – Request for Comments
I’ve written up a basic introduction, with pictures, to my field of research. I would really appreciate it if any of you could read it over, tell me if you find it understandable, what’s unclear, etc. I need people who aren’t very familiar with this stuff.
It’s lacking some later stuff that’s more relevant to my research (at this point) but I want to get the foundations right before I move on.
Please please please help me with this.

Leading Causes of Death in the US
People talking about cardiovascular disease research often mention that it’s the leading cause of death in the states. I went to look it up today and found the Center for Disease Control’s Leading Causes of Death Reports. You can break things down a number of ways. Cardiovascular disease is number one across all age groups, but up to age 34, #1 is unintentional injury. 35-64 it’s “Malignant Neoplasms” which I assume means cancer.
I guess I’d better try not to injure myself.
