There are devices called "holter monitors" that a person wears continuously and which measure your blood pressure frequently. I would call this continuous though it's more like every 15 minutes or whatever it's programmed for. It's all without your intervention. My ex bought one when they wanted more data about their high blood pressure.

I'm well aware of this, but this is different from what we're discussing here. While Holters measure continuously, they don't give you continuous feedback. The general procedure is that the data is either gathered and downloaded or sent over network and the patient sees it only after the gathering is done.

Because I fainted, I wore a holter monitor for a month that did not measure blood pressure but instead my EEG, uploading the data via the cellular network. My cardiologist said it measured about 1 million heatbeats in that time.
