Hypertension

Hypertension will be the subject of the next HeartChart. I am almost done…just a few popover text views to finish. This chart will use a long scroll view, to put more information on one page, and to simplify iPad rotation. Seems to be working out fairly well, though setting all the “constraints” in a scrollview seems more complicated than it should be. In addition to adding Hypertension to HeartCharts, I’m thinking of bring out this section as a standalone free app, so people could use it as something like a “free trial.”

Version 1.2 — Pacemakers

Last week the V 1.2 upgrade was approved by the App Store. A chart on Pacemakers was added. It opens with a diagram/animation of AV sequential pacing (wires in both the atria and ventricles, pacing in both chambers). This can be switched to a system showing sinus rhythm, with the pacer tracking the atria, then pacing the ventricles. There are the usual labels leading to further discussion about multiple of topics, including the Pulse Generator, the Leads, etc.

As usual, upgrades to iPad apps are free.

 

HeartCharts iPad App now available

I received an email from Apple at 1:15 AM on 7/12/2013:

“The status for your app, HeartCharts (669797925), is now Ready for Sale.”

Interesting that by the next AM, 3 individuals had downloaded the app…from Brazil, Netherlands, and Taiwan.

Now time to work on some new charts to add (I’m thinking Pacemaker, Myocardial Infarction, and Aortic Regurgitation).

 

App Store Review

The HeartCharts iPad App Version 1.0 is in the App Store for review as of 7/3/2013.

In anticipation of approval (!) information about the App has been added to this site. Choose “HEARTCHARTS APP” from the menu and take a look. There is a video, as well as screenshots and some explanation. The plan is to add more charts regularly in future versions.

Getting Started

This experience begins as somewhat of an afterthought.

What I’ve really been working on is an iPad app to use in my office for patient education. I’m a cardiologist, of the noninvasive type. That means I talk to patients, examine patients, diagnose patients, and treat patients. I evaluate patients with complaints that may or may not be from the heart, manage patients with heart disease, and try to prevent problems and complications as much as possible. I do stress testing and echocardiography, but not cardiac catheterizations, stents, ablations, pacemakers, or other such “invasive” procedures.

I spend a lot of time talking with conscious and alert people who want to know what is wrong with them, what is the nature of their problem, and what can be done about it. Other patients act like they don’t want to know any details, and I have to convince them that more knowledge has significant physical and emotional benefits. Then, of course, there are problems with incorrect assumptions and misinformation, perhaps not really related to an individual patient’s specific situation, ideas which they may have picked up from friends or family, the internet, news outlets, or even other medical people. So, educating patients turns out to be one of the most important things I do.

Next time I’ll get into where this desire for me to do a better job with patient education has been leading.
