Note that while diastolic blood pressure is diminished and the pulse pressure widens, systolic blood pressure generally remains normal or can even be slightly elevated. This is because sympathetic nervous system and the renin-angiotensin-aldosterone axis of the kidneys compensate for the decreased cardiac output.
Amazon Echo, also known as Alexa, is a voice command device from Amazon.com that is always listening. Its functions include question answering, playing music and controlling smart devices.
Amazon has a new Echo lineup with tiered-speaker heights that remind us of Starbucks coffee sizes (grande, venti, and trenta). Amazon makes a cylindrical, internet-connected Bluetooth speaker called Echo, which doubles as your personal, cloud-based assistant, addressed as Alexa. Now, one year after launching Echo, it is debuting two sibling speakers. The new ones are called Amazon Tap and Echo Dot. If you were to sit all three speakers next to each other, starting with the Echo and ending with the Dot, one would be tall, one would be medium, and one would be short.
