摘要：
Certain embodiments of the present invention are related to an implantable monitoring device to monitor a patients arterial blood pressure, where the device is configured to be implanted subcutaneously. The device includes subcutaneous (SubQ) electrodes and a plethysmography sensor. Additionally, the device includes an arterial blood pressure monitor configured to determine at least one value indicative of the patients arterial blood pressure based on at least one detected predetermined feature of a SubQ ECG and at least one detected predetermined feature of a plethysmography signal. Alternative embodiments of the present invention are directed to a non-implantable monitoring device to monitor a patients arterial blood pressure based on features of a surface ECG and a plethysmography signal obtained from a non-implanted sensor.
