Unreadable. 'Unreadable' implies that there was too much interference during the recording. This could be electrical or sound interference. Normal. If no rhythm abnormalities are detected, you will receive the message 'Normal'. This means that the heart rate is between 50 and 100 BPM, there are no or very few abnormal beats, and the shape, timing and duration of each beat is considered normal.

Recommended by doctors:A trusted resource, KardiaMobile is clinically proven with over 100 peer reviewed research articles and is used by leading cardiologists.ECG monitoring is a critical medical test that can detect abnormalities in the heart’s electrical activity such as irregular heart rhythms like atrial fibrillation, bradycardia, and tachycardia. Several smartwatches and other wearable devices can also provide data about your heart health, but these are often limited in their ability to detect abnormal heart rhythms. A portable ECG device will give your doctor the detailed information they need to diagnose cardiac issues. Other tips for avoiding poor recordings and unclassified readings include moistening your fingers if they are dry, concentrating on staying very still (which is easier if the KMC is flat on the table), and avoiding squeezing too hard. Instant analysis The single internal coin cell battery in the Kardia Mobile should last for approximately 1 year of normal use assuming 2-3 recordings a day. The skeptical cardiologist has gotten his hands on AliveCor’s brand new KardiaMobile Card and can confirm that it is an amazing development in the personal mobile ECG space.

The Kard communicates via Bluetooth with the smartphone app so make sure that Bluetooth is turned on on your phone. It is 85.6 mm x 54.0 mm x 1.2 mm, has two 25 by 15 mm electrodes, and weighs 7.4 grams. It runs off a non-replaceable lithium manganese oxide battery designed to last 2 years and utilizes Low Energy Bluetooth technology to communicate with most smartphones. As announced last week, the Kard is exactly the height and width of a credit card and performs high-quality single-lead ECGs in a manner similar to AliveCor’s larger KardiaMobile. The Kard Proven. KardiaMobile’s single lead ECG is comparable to Lead 1 of a standard ECG machine, and the most clinically validated mobile ECG solution available.
