The Omron HEM-670IT Wrist Blood Pressure Monitor uses Omron's patented IntelliSense technology, which inflates the wrist cuff to the ideal level with each use and offers fast, personalized, and automatic inflation for maximum comfort. No adjustments are required to select an inflation level--especially convenient for hypertensive users and for people with certain arrhythmia or heart disorders, because their blood pressure is more likely to fluctuate. And with the HEM-670IT's 100-memory recall with date and time stamp, as well as averaging capabilities for the last three readings, you can track your blood pressure and pulse progress as your work towards a healthier lifestyle. The HEM-670IT also features a system that detects an irregular heartbeat as well as morning hypertension, giving you an even better understanding of your heart's health. A built-in hypertension indicator lets you know if your readings indicate a high-blood pressure condition. Plus, you'll have additional peace of mind knowing that the HEM-670IT comes with a 5-year warranty.
