Tuning of a heart pacemaker through the use of blood pressure and cardiovascular readings
First Claim
1. A method of tuning a heart pacemaker comprising the steps of(a) using an electrocardiographic device to adjust the firing sequence of the pacemaker,(b) affixing a non-invasive pressure inducing means and transducer means to the patient,(c) elevating the pressure induced by the pressure inducing means to a suprasystolic pressure,(d) decreasing the pressure induced by the pressure inducing means over time to a subdiastolic pressure,(e) obtaining a data stream from the transducer means, the data stream including pressure data and pulsation signal data,(f) examining the information stream to detect cardiovascular irregularities displayed in the information stream, and(g) repeating steps (e) to (f), if necessary, to minimize the cardiovascular irregularities displayed in the information stream.

Abstract
A method is disclosed for determining the blood pressure of a patient. The method includes the steps of affixing a non-invasive pressure inducing device and transducer to the patient. A data stream is obtained from the transducer. The data stream includes pressure data and pulsation signal data. The data stream is processed to create an information stream which coorelates the pressure data and the pulsation signal data. The information stream includes at least two pulse maximum points and at least one pulse minimum point. At least one of the systolic, diastolic and mean arterial pressure of the patient are determined by choosing a pressure determination point in the information stream between the two pulse maximum points. Additionally, an apparatus for determining blood pressure is disclosed.

4. The method of 2 wherein the step of examining the information stream comprises the step of examining the information stream curve to determine at least one of the patient'"'"'s systolic, diasolic and mean arterial blood pressure, to determine whether said at least one of the patient'"'"'s systolic, diastolic and mean arterial blood pressure falls outside of a physiologically acceptable range.
