  • a lead adapted for implantation in a subject and carrying sensor means for obtaining blood flow velocity data, said blood flow velocity data including data identifying at least one blood flow velocity wave produced after each heartbeat;

    means for obtaining heartbeat data identifying successive heartbeats of said subject; and

    control means, supplied with said blood flow velocity data and said heartbeat data, for identifying respective measured values of successive occurrences of said at least one blood flow velocity wave and for generating a signal indicating detection of venous pooling if a decrease of said measured values is preceded at an increase in a rate of said heartbeats.
