Who can use Observer ECG EKG Monitor?

Heart related diseases kill more than all the cancers combined. They are also called the silent killer, as you may not have any symptoms until the heart attack. Or you may feel discomfort sometimes, but by the time you visit the clinic, the symptoms are gone. Monitoring your heart's health condition is one of the vital steps towards a long and healthy life. This new version of Observer Handheld ECG machine, is a device with which you can record your heart's electrical activity in just 25 seconds, view the key parameters on the LCD screen, and later print the trends in heart activity to help your physician detect CardioVascular Diseases. Monitoring heart's rhythm is made easy, as it is a palm-sized device which can take measurements at any time, in any place, whether it's while eating in a restaurant, after exercising in a fitness center, or after taking a specific drug.

How does Observer work?

Electrical waves travel through the heart chambers to charge and trigger heartbeats. If the heart's chambers are not synchronized, the blood will not circulate effectively, which can be a symptom or cause of CardioVascular disease. With ReadMyHeart, you can measure and record your heart's electrical signals as they are emitted through your body. When your thumbs are in contact with the dry electrodes, the palm-sized device is able to trace and record the micro-current your heart generates during heartbeats, generating the related heart function parameters (PR, QRS, ST).ReadMyHeart is hassle-free: the LCD displays your key heart parameters (QRS, ST), blinks if they are out of range and stores up to 30 records.
