Dear 43 Things Users,

10 years after introducing 43 Things to the world, we have decided we have met our last goal: completing the incredible experience that has been 43 Things. Please join us in giving one last cheer to all the folks who have shared their goals with the world, as well as all the people who have worked at The Robot Co-op to build this incredible website. We won a Webby Award, published a book, and brought happiness to a lot of people.

Starting today, 43 Things users can export their goals and entries from the site. Starting August 15, we will make the site “read only”. 43 Things users will still be able to view the site and export their content, but we won’t be taking any new content from users. We hope to leave the site up for folks to see and download their content until the end of the year. Ending on New Year’s Eve takes us full circle.

It has been a long ride (one of our original goals was to "build a company that lasts at least 2 years” - we beat that one!) While we wish the site could live on, it has suffered from a number of challenges - changes in how people use the site, the advertising industry, and how search engines view the site. We wish the outcome was different – but we’ve always been realistic about when our goals are met and when they aren't.

As of today, you will be able to download your goals and entries. See more about that on the FAQ page. Thanks for 10 great years of goal-setting and achieving.

- The Robots.

review my Rhythm strips. (read all 14 entries…)
Sinus w/PJC

Arrhythmia Recognition:
Premature Junction Contractions
Rate: Usually single events
Regularity: Regular with an event
P wave: Variable
Morphology: Inverted
Upright in II, III, aVF: Inverted
P:QRS Ratio: Variable
PR Interval: Short, if present
QRS Width: Normal
Grouping: None
Dropped Beats: None

Note: Normally, PJCs are benign and cause no hemodynamic compromise. To tell the difference between a PAC and a PJC, look at the following four points. 1. Always look for morphological variation in the preceding T-wave which could indicate a buried P-wave (PAC). 2. PACs usually have a non-compensated pause. PJCs can have either compensatory or non-compesenatory pauses. If there is a compensatory pause, then it is definitely a PJC. 3. Inverted P-waves in Leads II, III and aVF with short PR intervals are usually indicative of PJCs. 4. Look for aberrancy in the QRS to distinguish between PJC and PVC. If the beats start in the same direction then change, it’s a PJC. If they start in opposite directions, then it’s a PVC.

Strip: This strip shows a nice sinus rhythm clipping along at 80 BPM. The cadence of the ventricular complexes is broken up by a premature complex that is narrow and similar in morphology to the rest of the complexes. This is obviously a PJC. The cadence of the atrial complexes, however, is not broken and persists right through the PJC making this a compensatory pause. Notice the buried upright P wave within the PJC (blue arrow). The fact the P wave is upright means that it did not come from the PJC.

Differential Diagnosis:
1. Idiopathic and benign
2. Anxiety
3. Fatigue
4. Drugs: nicotine, alcohol, caffeine, etc.
5. Heart disease
6. Electrolyte disorders
