Terms and Other Useful Information
This section will explain some medical terms used in the sections above and heart-related symptoms.
Lead I ECG
According to the Utah University website, 12-lead ECG holds spatial information about the heart’s electrical activity in 3 orthogonal directions. Each of the 12 leads shows a specific orientation in space. Among them Lead I indicate Right Arm (-) to Left Arm (+). This means that the Kardia Mobile device can sense the leads from your right and left arms and interpret the signals.
Atrial Fibrillation (AF)
According to Mayo Clinic, a health website, Atrial Fibrillation is an irregular and rapid heart rate that can lead to strokes, heart failure, and other heart-related complications. Some patients with AF have no symptoms thus are unaware of the condition. They find out about the condition when they take a physical exam. Those with AF symptoms may experience the following:
- Palpitations (irregular, uncomfortable, or racing sensation or flip-flopping in your chest)
- Weakness or reduced ability to exercise
- Breath shortness
- Chest pain
Since the symptoms are not very apparent, Kardia Mobile can be useful to detect the symptoms.
As of July 9th, 2019, AliveCor Kardia Mobile is priced at $109.99 USD on Amazon.
How Customers Think About Kardia Mobile
When you see product introduction from a company, you will always hear great things about it. No company will reveal any weaknesses or defects of the product, obviously. So, as a consumer, it is wiser to doubt what they say and do your own research before making a final purchase decision. In this section, we will learn how actual users think about Kardia Mobile. How can we measure these? We can do this by using data analysis techniques called sentiment analysis.
You don’t have to be scared by the technical term. I did the technical part and you can just look at pretty graphs. In this section, I will show you two types of graphs – word cloud and customer sentiment chart. For the analysis, I’ve compiled more than 2,400 customer reviews from Amazon and conducted analysis to summarize them. I will show you the result in a word cloud and a customer sentiments chart. And, lastly, I will share a Kardia Mobile’s Google trend result that shows the level of interest from people.
Word cloud is one of the great and fun ways to understand customer sentiments toward a product or a service. In a word cloud, you can see specific words in different sizes. The larger it is, the more people used that word to describe the product. For this word cloud, I used the titles of the reviews, since people put the essence of their opinions in the title. The 2,400+ reviews allowed me to generate an interesting word cloud that let me reach a positive conclusion. Let’s have a look!
Understanding the word cloud is easy. Just follow your eyes and see what you see. You will see that most of the big words are all positive. This means that customers have had a positive experience with the service. People used words like “fivestars”, “great”, “good”, “easy”, “worsgreat”, and more positive terms to describe this product.
In the word cloud, we were able to observe what descriptive words people used to talk about Kardia Mobile. As mentioned, the word cloud is based on the titles of customer reviews, but the sentiment analysis graph was generated by the contents of the reviews. In the sentiment analysis, we will see more specific types of feeling that people showed in their review. In the analysis, you can see 10 different sentiments such as positive, negative, trust, anticipation, joy, fear, sadness, anger, surprise, and disgust.
The technology behind the chart is straightforward. The analysis algorithm holds 10 different lists – each list containing words that are mapped to one of the 10 sentiments. When this algorithm runs, it checks and matches with one of the sentiments. When matched, it is counted as one and is categorized in one of the 10 sentiments. My analysis of the positive reviews appears as below.
The chart is also not difficult to understand. You can see that the positive sentiment is ranked number one. The first rank is followed by “negative”, “trust”, “anticipation”, “sadness” and “fear”. It does have some negative opinions, but overall, people expressed more positive sentiments than negative ones. So my customer review analysis told me that many people have a positive experience with the health device.
As the final segment of analysis, let me share the trend of Kardia Mobile. I used Google Trend to check how frequently “Kardia Mobile” is searched on Google over the past 3 years. Google Trend is a useful tool to measure the interest of people. The more frequently people search on Google, the more popular or trendy it is. The Google Trend (may not visible on a mobile phone) of the product below shows that people have consistently shown an interest in this heart monitoring device over the period.
This continuous interest for 3 years could be a positive sign for a purchase decision.
Please note that this is a global trend. If we break down by country, we can see that the biggest interest has come from the United States followed by Canada, the United Kingdom, France, and Germany. To see the country list, click the list icon at the bottom right, and it will turn to the list.
If you are worried about your heart health or if you are a heart doctor, having a portable health monitoring device won’t be a bad idea. My analysis on customer reviews and Google Trend support that KardiaMobile has received positive feedbacks and constant attention from people.
Please mind that you may want to consider to pay the premium subscription fee for more features. As I researched the customer reviews, many people were not aware that the premium features are not free. You can start with the free trial, of course. But, be prepared that you might want to pay the subscription fee.
