Patent ID: 8509892

Claim:
A cardiac rhythm management system, comprising: a hemodynamic tolerability analyzer including: a hemodynamic parameter input configured to receive values of one or more hemodynamic parameters including values of the one or more hemodynamic parameters sensed during delivery of pacing pulses according to a hemodynamic challenge protocol, the hemodynamic challenge protocol specifying an incrementally increasing pacing rate such that the pacing pulses arc delivered to induce increasingly severe tachyarrhythmia; an annotation input configured to receive annotations associating the values of the one or more hemodynamic parameters to levels of hemodynamic tolerability each being a measure of tolerance to deteriorated hemodynamic performance resulting from tachyarrhythmia; and a hemodynamic tolerability map generator configured to generate a hemodynamic tolerability map relating at least the values of the one or more hemodynamic parameters to the levels of hemodynamic tolerability; and a control circuit configured to control the delivery of pacing pulses by executing the hemodynamic challenge protocol.
