Abstract
A medical device and method conserve electrical power used in monitoring cardiac arrhythmias. The device includes a sensing circuit configured to sense a cardiac signal, a power source and a control circuit having a processor powered by the power source. The control circuit is configured to operate in a normal state by waking up the processor to analyze the cardiac electrical signal for determining a state of an arrhythmia. The control circuit switches from the normal state to a power saving state that includes waking up the processor at a lower rate than during the normal state.
Claims27
A medical device, comprising:
- a sensing circuit configured to sense a cardiac signal;
- a power source;
- and
- a control circuit comprising a processor powered by the power source, wherein the control circuit is configured to:
- operate in a normal state by waking up the processor at a first rate to analyze the cardiac signal for determining a state of an arrhythmia;
- switch from the normal state to a power saving state that uses less electrical power from the power source than the normal state in determining the state of the arrhythmia;
- and
- operate in the power saving state by waking up the processor at a second rate to analyze the cardiac signal for determining the state of the arrhythmia, the second rate being less than the first rate.
A method, comprising:
- sensing a cardiac signal;
- operating in a normal state by waking up a processor at a first rate to analyze the cardiac signal for determining a state of an arrhythmia;
- and
- switching from the normal state to a power saving state that uses less electrical power than the normal state in determining the state of the arrhythmia;
- operating in the power saving state by waking up the processor at a second rate to analyze the cardiac signal for determining the state of the arrhythmia, the second rate being less than the first rate.
A non-transitory, computer-readable storage medium comprising a set of instructions which, when executed by a control circuit of a medical device, cause the medical device to:
- sense a cardiac signal;
- operate in a normal state by waking up a processor at a first rate to analyze the cardiac signal for determining a state of an arrhythmia;
- switch from the normal state to a power saving state that uses less electrical power from a power source of the medical device than the normal state in determining the state of the arrhythmia;
- and
- operate in the power saving state by waking up the processor at a second rate to analyze the cardiac signal for determining the state of the arrhythmia, the second rate being less than the first rate.
