ECG: Corrected QT

Hello again! Finally, we're back with our newest android-based application. What is it this time? Yap, still wandering around ECG thingy, now we proudly present the ECG: Corrected QT application. 

Around many aspects to interpret in ECG recording, QT interval is one of the most important. QT interval is the duration between the beginning of Q wave and the end of the T wave. Its duration in ECG recording represents the time taken for ventricular depolarization and repolarization. An abnormally prolonged QT interval is associated with an increased risk of ventricular arrhythmias, especially Torsades de Pointes. Meanwhile, the recently described congenital short QT syndrome has been found to be associated with an increased risk of paroxysmal atrial and ventricular fibrillation and sudden cardiac death.

On the other hand, QT interval is affected is affected by heart rates. The QT interval is inversely proportional to heart rate. It will shorten at faster heart rates and lengthens at slower heart rates. Then, how can we surely estimate if one QT interval is normal? It is recommended to interpret the normal values of QT interval based on the corrected QT (QTc), in order to avoid the effects of heart rate on QT values. By calculating the QTc, we can do a comparison of QT values over time at different heart rates and improves detection of patients at increased risk of arrhythmias. By simply click this link or the badge below, estimating the corrected QT interval would never be this easy!

Get it on Google Play

Why should you choose ECG: Corrected QT?
- It is simple and very easy to use.
- The calculation is precise and accurate.
- Based on 3 most commonly used formulas, Bazett, Fredericia, and Framingham.
- It is totally free!

The corrected QT interval (QTc) will estimate the QT interval at a heart rate of 60 beats per minute. In order to achieve the QTc value, you need to input the QT interval (in msec) and the heart rate (in beats per minute). QT interval should be measured in either lead II or V5-6. Several successive beats should be measured, with the maximum interval taken. After that, the application will automatically do the math for you, using 3 available formula, namely Bazett, Fredericia and Framingham formula. Bazett's formula is the most commonly used because of its adequate correction for heart rates ranging from 60 - 100 bpm. But it over-corrects at heart rates >100 bpm and under-corrects at heart rates <60 bpm. At heart rates outside of the 60 - 100 bpm range, the Frederica or Framingham corrections are more accurate and should be used instead. 

The interpretation of QTc value is as follows. QTc is prolonged if >440 ms in men or >460 ms in women while QTc is abnormally short if <350 ms. QTc >500 ms is associated with increased risk of Torsades de Pointes. Now, based on the QTc result, the physician can determine whether the patient has an increased risk of arrhythmia and planning further diagnostic step and therapy. Here is the preview of our apps on Google Nexus 4.

ECG: Heart Axis

Hello, everyone! Back with us again, the imedical-apps team. Now we're going to give you sneak a peak about our new application ECG: Heart Axis

The idea of making this new application popped up when we're trying to interpret a series of ECG recording, and find it complicated to get the exact heart axis by calculating the vector manually. Heart axis or cardiac axis is the direction of action potentials during ventricular depolarizations. Knowing heart axis is important, as some abnormalities of the heart structure could make the heart deviates from its normal axis. 

Actually, we could get the gross heart axis just by determining the resultant deflection of the QRS complex in lead I and AVF. For example, if the QRS complex has a positive deflection in both lead I and AVF, we can conclude that the heart axis is normal (lies between 0 to 90 degree). But what if one of the QRS complex, either in lead I or AVF, has a negative deflection? Is that always counts for an abnormal heart axis? Think again. Normal heart axis lies between -30 degree to 120 degree. So if the negative deflection of QRS complex happened only in lead I, one still has the probability of having normal heart axis (as it still has a probability of having lies between 90 degree to 120 degree). 

Then, how could we differentiate that? Simply tap on this link or click the badge below.

Get it on Google Play

ECG: Heart Axis  is a simple application to determine heart axis from a simple ECG recording. It works by calculating the resultant vector from the QRS complex in lead I and AVF automatically. The electrical heart axis will then be shown in vector degrees. By simply putting the resultant QRS deflection (mm), the application will give you one of the four interpretation results, namely normal heart axis, left axis deviation (LAD), right axis deviation (RAD) and extreme axis deviation.

ECG Heart Axis

The resultant QRS deflection (mm) could be achieved by calculating the resultant amplitude of R wave and S wave (or Q wave if any). If the R wave comes in a positive deflection (e.g +5 mm) and the S wave comes in a negative deflection (e.g -2mm), then we get the resultant QRS deflection of 3 mm. Easy, right? Then you could just let the application do the math for you. 

ECG Heart Axis

Why should you choose ECG: Heart Axis?
- It is simple and very easy to use.
- The calculation is precise and accurate.
- The electrical heart axis is shown in vector degrees.
- Interpretation result is provided.
- It is totally free!

Pregnancy Calculators Pro

Hi, everyone! It's not so long ago since the third post and now we're proudly present our recent app called the "Pregnancy Calculators Pro". Different from the previous app, this one app is also targeting the larger market outside the medical health professionals. But still, we provide it free for you guys, as free as the air we're breathing into. Just simply click on this link or the badge below to have it in your hands!

Get it on Google Play

As you can imagine by only reading the title of the app, this one app will give you a lot of information regarding every aspect of pregnancy. It is designed to help not only the medical professional but also general population without a medical background to understand more about their pregnancy. 

Why should you choose "Pregnancy Calculators Pro"?
  • Simple and very easy to use.
  • Precise calculation with most used formula.
  • Find out your gestational age and estimated due date with just one click.
  • Estimate your gestational age based on several ultrasonography biometry.
  • Find out your baby's weight.
  • Some useful pregnancy recommendations and tips are provided.
  • It is totally free.
  • A lot of features and more! Download now!

There are 4 main features that we're provided:
  1. Calculate the gestational age of your pregnancy based on the first day of the last menstrual period.
  2. Calculate the gestational age of your pregnancy based on biometry of the fetus measured in ultrasonography.
  3. Calculate the estimated birth weight of your baby based on biometry of the fetus measured in ultrasonography.
  4. Several tips and recommendations cited from the American Congress of Obstetricians and Gynecologists regarding some important aspects of pregnancy.
Estimating the gestational age of the pregnancy is one of the most important parts during the first antenatal visit. One of the most common and easiest ways to estimate the gestational age is using the first day of last menstrual period. This estimation assumes that conception occurs on day 14 of the cycle, therefore, this method is suitable for women having regular menstruation cycle of 28 days. While estimated due date is calculated by adding 280 days (40 weeks) to the first day of last menstrual period. But calculating gestational age using the last menstrual period is hard to do if the menstrual cycle wasn't regular and the mother was unsure of the exact date of the last menstrual period. That's when the second feature of this app takes part.
Pregnancy Calculators Pro Preview
The second feature of this app allows the physician to estimate the gestational age and delivery due date based on the biometry of fetus measured in ultrasonography. There are 3 biometry that can be used in estimating the gestational age, such as crown-rump length (CRL), biparietal diameter (BPD) and head circumference (HC). Crown-rump length is used mainly in 1st-trimester measurements while biparietal diameter and head circumference are commonly used in 2nd and 3rd-trimester measurements.
Pregnancy Calculators Pro Preview
As we know, not all the ultrasonography device used nowadays allows the physician to measure the fetal weight automatically. By using 2 most common formulas, Hadlock and Shepard formula, the physician can estimate the fetal weight using fetal biometry measured in ultrasonography. Hadlock formula works by using fetal length (FL) and abdominal circumference (AC) in the calculation while Shepard formula estimate the fetal weight based on biparietal diameter (BPD) and abdominal circumference (AC). By simply putting the necessary information needed from fetal biometry, the app will do the math for you!
Pregnancy Calculators Pro Preview
The last but not least, we also put several tips and recommendation regarding some important aspects in pregnancy, including the recommended frequency of antenatal visits, immunization schedule, recommended weight gain during pregnancy, mineral and folate supplementation, recommended diet, and exercise in pregnancy. All the recommendation written was cited from the American Congress of Obstetricians and Gynecologists (ACOG) website.

Hypernatremia Correction Rate

Hello, all! This is the third post (and more to go) already. I hope since you guys are into this page, you find our previous apps helpful and willing to read more about our apps.

Since the previous app was about correcting the hyponatremia condition, this one is about reversing the hypernatremia state back into normal. It is an android-based mobile application called "Hypernatremia Correction Rate". You can download it free on Google Play Store by simply clicking this link or the badge below.

Get it on Google Play

Hypernatremia Correction Rate is an app intended to help medical professionals in calculating the rate of infusion needed to correct the elevated sodium level in blood. Hypernatremia is a condition that occurs when serum sodium level is high (>145 mmol/L). The main concept is to correct the hypertonicity caused by elevated sodium levels with the replacement of free water. There are 2 different conditions that affecting the rate of infusion in correcting hypernatremia, the acute and chronic state of hypernatremia. Acute symptomatic hypernatremia should be corrected rapidly while chronic hypernatremia should be corrected more slowly. That's the point where Hypernatremia Correction Rate will help the doctor in adjusting the correction rate used by the infusate to avoid over or under correction.

Why should you choose Hypernatremia Correction Rate?
  • Simple and very easy to use.
  • Precise calculation using Adrogue formula.
  • Selection of most used fluids in treating hypernatremia.
  • You can adjust the correction rate based on clinical judgment.
  • The result will be shown in the amount of selected fluids per hour.
  • The result is also showing intravenous fluid drips (IVFD) rate with drop factors of 20 gtt/ml and 15 gtt/ml.
  • Applicable for the doctor in a remote hospital without syringe pump.

The calculation done by this application is based on Adrogue formula. This formula is preferred over the conventional equation for water deficit because this equation proven useful in situations in which sodium and potassium must be used in the infusate. To obtain the correct infusate rate based on selected fluid, user can simply input the patient's information such as weight, the blood level of sodium, age category in years, sex and preferable kind of fluid to be used as infusate. Then simply by clicking 'submit', the result will appear in split second.
Hypernatremia Correction Rate Preview
The result page will show the volume of fluid needed and the number of IVFD rate in gtt/minute (by the drop factor) based on the selected fluid chosen. The result can be adjusted by selecting the amount of estimated insensible water loss so that it can be included/excluded in the calculation of the volume of fluid needed. The default rate of sodium decrement needed per hour shown is 0.5 mmol/L/hour, but it can be adjusted based on physician's preference.
Hypernatremia Correction Rate Preview
The other important feature in this app is the safety range of correction rate shown based on the current acute/chronic state of hypernatremia. It is vital to distinguish this two condition because it can lead to brain edema if a chronic state of hypernatremia was corrected rapidly simply because the calculation did not include that as a vital part to be considered. In acute hypernatremia, the initial sodium correction rate should be 2-3 mEq/L/h for 2-3 hours, with the maximum increment of 12 mEq/L/day. However, chronic hypernatremia with no or mild symptoms should be corrected at a rate not to exceed 0.5 mEq/L/h and a total increment of 8 - 10 mEq/L/day.

The result also shows the number of intravenous fluid drip rate in gtt/minute. This feature will help doctor from a remote hospital that doesn't have syringe pump. Therefore, the doctor should know the drop factor of their infusion set. On this application, we only show the drip rate for common drop factor used, such as 15 gtt/ml and 20 gtt/ml. Drop factor of 15 gtt/ml means that it takes 15 drops from the infusion to be as equal as 1 ml.

The application is still far from perfect. Therefore, we expecting any comment, suggestion or even testimonial to make this app a better one. Please kindly contact us at We are looking forward in making another useful medical application in the near future, so stay tuned on this website and don't forget to give a good review and rate our apps!
