iMurmur is an exciting, practical application that teaches you how to recognize and diagnose heart murmurs. Without a doubt, the sounds contained in iMurmur's library will be heard in clinic. The heart sounds are presented in a rapid quiz format and are organized by clinical relevance emphasizing sounds you will encounter most frequently. In addition to a visual diagram of each murmur, you have the option to learn more; you can read about key clinical characteristics, what generates the murmur's unique sound, its pathology, and basic concepts on how to proceed with therapy. iMurmur also includes options to create custom quizzes or to listen to specific murmurs from the collection.

Repetition is the branding iron of knowledge and this application may help make healthcare providers better at recognizing various heart sounds. Students of all backgrounds, including medical, nursing, paramedic, emergency medical technician, pharmacy, physical therapy, and occupational therapy, will discover that iMurmur is an enjoyable and efficient way to learn. Professionals, including MDs, DOs, PAs, NPs, RNs, NDs, paramedics, EMT-Bs, DPTs, OTDs, MPTs, MOTs, residents, and interns, will find that iMurmur is a fun, interactive way to brush up on auscultation skills. Medical students studying for Step 1 and Step 2 of the USMLE (United States Medical Liscencing Exam) will find iMurmur extremely high yield in preparing for the cardiac multimedia questions. In addition, iMurmur is straightforward and can be used by anyone interested in learning about heart sounds and conditions.

"Reasoning is over-rated. In time, you will know a heart murmur not because you reasoned your way to the answer, but because you have heard it before. When confronted by Grandma you don't stop and think, "Hmm, elderly woman, short, white hair, smells funny... AH! By this train of thought, this is Grandma!" No. You know Grandma because you've seen her before."
-Dr. Larry Hansen, Professor of Pathology,
U.C. San Diego


The heart sounds have a very deep pitch that the built-in speakers cannot reproduce; HEADPHONES MUST BE USED FOR OPTIMUM QUALITY. Compatible with iPhone and iPod touch.
Requires iPhone 2.2.1 or 3.0 Software Update.
