{
"rating": 2,
"title": "Just ok",
"body": "This is not nearly as detailed as I hoped it would be. It gives only a brief description of the 12 leads, and doesn't delve into the meaning of them. For example, one shows LVH with \"strain pattern,\" but doesn't tell you what LVH is, how to detect it, and what it means. Nor does it do so with the strain pattern. There are no quiz questions beyond simply showing you 12 leads. Very frustrating! This app is overpriced for what it is. It should be .99.",

"rating": 4,
"title": "A bug and a little more",
"body": "First I want to say it is a good app. Great ECG's that will give you a great study tool. The only thing that slows me down right now with it is when I zoom in to take a closer look at the ECG's the images are extremely touchy. What I mean is when I try and move the ECG around with my finger, after about 10 seconds of it being zoomed in, the ECG's will jump from one end of the ECG to the other when I try and only move it from lead 1-3 over to maybe V1-V3. And sometimes it moves it completely off the screen and I have to try and find it or give up and zoom out. But the ECG images themselves are great quality and a great challenge. Second the app could be even better if there was maybe a study section that showed examples and explanations of the STEMI mimics. I'm sure the app is large enough but a small section that gave a better explanation of what benign early re-polarization looks like would in my mind makes this app the ultimate 12 lead study app. Great work!!!",

{
"rating": 4,
"title": "Good",
"body": "As a paramedic I love having the ability to test my diagnostic ability for 12 leads. This is a good program to see a lot of interesting ECGs. Its limits are that it is not a \"great\" teaching tool. It does go a little into the diagnostic criteria for each slide but you need to already have a pretty solid background in those areas for it to mean anything. I unfortunately had a pretty poor classroom education for 12 leads and have had to take it upon myself to learn as much as I could. Overall a good program.",

{
"rating": 5,
"title": "Awesome app",
"body": "As a new paramedic, I really need a handy tool to help me stay sharp on 12-lead analysis and this app delivers. Its sleek, simple design eliminates all the noise and lets you concentrate on making the crucial decision: Do I activate the cath lab? I hope the designers continue to update and add more 12-leads for conditions beyond the AMI. There are a handful of them here (Brugada, WPW, etc.), but in this case more is better.",
