Heart Rhythm

The heart rhythm can be regular or irregular.
Irregular rhythms can be either:
  •      Regularly irregular (i.e. a recurrent pattern of irregularity)
  •      Irregularly irregular (i.e. completely disorganised)
Mark out several consecutive R-R intervals on a piece of paper, then move them along the
rhythm strip to check if the subsequent intervals are the same.

Hint – if you are suspicious that there is some atrioventricular block, map out the atrial rate
and the ventricular rhythm separately (i.e. mark the P waves and R waves). As you move
along the rhythm strip, you can then see if the PR interval changes, if QRS complexes are
missing or if there is complete dissociation between the two.

Easy Emergencies

Hi, I am back again. Today I finished my third app after a hard work. I call it "Easy Emergencies".  In this app, I covered the most common topics that a practitioner face in his clinic or in an ER. Subjects like Anaphylaxis, Animal bites, MI, Coma, Diabetic Ketoacidosis and etc. I designed it in a way that you can jump to a topic that you want. For example, if you need to know to manage full partial burnings, just click on the button of management and ignore the rest of the data to save your patient time. Here are some screenshots: You can Download it HERE or scan the barcode below: Cheers Max

Patient Referral Criteria

-

     One of the biggest struggles in practice for emergency doctors and primary health care practitioner is how and when to refer a case to secondary or tertiary healthcare.    After many case-study and getting feedback from my colleagues and friends, I came up with an idea to develop an application for Android mobile to tackle this issue.  I call it "Patient Referral Criteria" which is an online application and it is available in Google Play  in the world over. I got much positive feedback from the users. I tried to cover main emergencies situations and show how to manage them by flowcharts and diagrams.    Here are some screenshots: You can download it here  or you can use your barcode scanner and scan the barcode below: Cheers
