Aortic insufficiency causes both volume overload (elevated preload) and pressure overload (elevated afterload due to increased stroke volume) of the heart. The volume overload (due to elevated pulse pressure and the systemic effects of neuroendocrine hormones) causes left ventricular hypertrophy (LVH).
Echo Dot is a hands-free, voice-controlled device that uses the same far-field voice recognition as Amazon Echo. Dot has a small built-in speakerâit can also connect to your speakers over Bluetooth or with the included audio cable.
The Tap is a smaller, mobile version of the Echo, whose power cord keeps it stuck indoors. The Dot is meant to connect to your existing sound system, bringing Echoâs smarts to the speakers you already own. Both devices function almost identically to the Echo. And both are compatible with all the great third-party apps (called âskillsâ) that already exist for that device.
