Heart is an amazing organ and anyone interested in anatomy is immediately attracted by this fascinating organ. This application presents the overview of the basic anatomy of the human heart. The information is divided into five sections and each section has its own menu at the bottom. The illustrations depict the basic anatomy of the heart which is the main focus of this App. The App was first launched as an iPhone App in 2010. Since then, it has been downloaded by thousands of people across the world from high students, graduate and medical students, to teachers and physicians.

As with iPhone version of this App, we feel that this simple and easily accessible information on iPad can be a handy resource for medical students, nurses, interns, residents, fellows and physicians. It can be specially useful to physicians and nurses as a quick review of the basic anatomy and for patient's education about the heart in a "Show & Tell" format. All illustrations depict normal anatomy in this App. You will find in this App the basic anatomic illustrations about the heart in a simple and concise format. Systematic approach is used to present information about the origin of the heart formation in embryo to its more complex fully formed structure. In addition to drawings, there are few video clips showing coronary angiogram and Echocardiogram. The user will find it very useful for a quick review and understanding of the structure and function of the heart. Once installed on the iPad, all the illustrations and media are included and there is no internet connection required.



About The Illustrations

All the illustrations for this App are hand drawn by Maham Karatela & Rizwan Karatela. Meticulous pen sketches are imported into Adobe Illustrator CS5. They are vectorized and color coded to give it a modern look for electronic medium. While every effort is made to make most of the illustrations zoomable there are few that are not zoomable due to the technical limitations. The references for these illustrations are among the most authentic references in cardiology and anatomy. All texts are scrollable.

The Description of TOC

The section consist of the fascinating facts about the heart, origin of the heart, the basic embryology, the formation of heart loop, the formation of septations within the heart, the surface anatomy of the heart with landmarks and the coronary segments and heart perfusion.



Coronary Circulations:
The section shows the coronary arteries and the circulation for the heart. The three epicardial coronary arteries and its branches are depicted here. In addition you will find video clips of cardiac catheterization showing coronary arteries as seen in angiograms.




Chamber Anatomy & Myocardium
The section presents information related to the four chambers of the heart, right and left atria and right and left ventricles, ejection fractions and hemodynamic information related to each chambers. A video clip (Echocardiogram) of the heart is located in this section to show the dynamic action of heart chambers and myocardium.

Cardiac Valves:

The complex structures of the four heart valves, namely Tricuspid, Pulmonary, Mitral and Aortic valves are depicted here. The video clips of the Echocardiogram shows the dynamic motions of the mitral and aortic valves.


Conduction System of the Heart:

The origin of the heart beat and its propagation through out the heart is shown here. From SA node to Purkinje fibres and ECG correlation of the events are summarized here. A very detailed diagram illustrating the various stages of cardiac cycle and its events and hemodynamic changes occurring throughout the cardiac cycles are noted.


The meticulously arranged various events of ECG with simulteneous tracings from RA, RV, LA, LV, Aorta and Pulmonary artery. The various phases of cardiac cycle are labeled and its corresponding events and hemodynamic changes.




With the explosion of mobile computing and the tremendous grwoth of iPhone Apps we can do much more.
