1. A method of regulating drug administration to a patient, comprising:
- administering a drug at an initial dosage level to a patient via a drug delivery unit;
monitoring a cardiac signal using a cardiac monitoring unit; and
reducing to a reduced dosage level that is lower than the initial dosage level when the monitored cardiac signal indicates a healthy cardiac sinus rhythm is present for at least a predetermined amount of time.

Abstract
Drug delivery methods and systems that include a determination of whether a cardiac condition is normal or abnormal, so that a drug may be administered in accordance with that determination. In one implementation, a drug delivery device may be controlled to reduce or stop the drug administration when a normal cardiac condition is detected. In another implementation, a patient monitoring device determines the duration that a cardiac condition is normal and provides an output indicative of the determination so that the patient may alter a therapy accordingly.

25. A patient monitoring and notification system, comprising:
-
a cardiac monitoring system comprising a cardiac condition sensor and a processing unit adapted to receive cardiac signals sensed over a time period by the cardiac condition sensor;
determine from the received cardiac signals a time measure indicating a duration of the time period that a cardiac condition is normal; and
generate, from the determined duration of the normal cardiac condition, prescriptive information relevant to an on-going therapy being administered to the patient; anda user notification device adapted to receive the prescriptive information from the cardiac monitoring system, and provide a user output adapted to inform the user as to how the therapy should be administered. - View Dependent Claims (26, 27, 28)

29. A drug infusion system comprising:
-
a cardiac monitoring unit adapted to sense, from a subject, cardiac signals from which a sinus rhythm condition is evidenced if present; a drug delivery unit adapted to contain and deliver to the patient an anticoagulant drug; and a processing and control unit adapted to receive the sensed cardiac signals, perform an assessment of sinus rhythm, and control delivery of the anticoagulant drug by the drug delivery unit based on the assessment of sinus rhythm. - View Dependent Claims (30, 31, 32, 33, 34)

35. A method for providing anticoagulant therapy to a patient having an atrial fibrillation condition, the method comprising:
-
controlling, at a programmed initial dosage level, infusion of an anticoagulant drug from a drug delivery unit to a subject; monitoring cardiac signals of the subject, and determining from the monitored cardiac signals if there is present an improved condition indicative of a reduced risk of blood clotting in the subject from atrial fibrillation; and if the improved condition is determined to be present, controlling the infusion of the anticoagulant drug from the drug delivery unit at a reduced dosage level that is lower than the initial dosage level. - View Dependent Claims (36, 37, 38, 39)
