Optimization of Pacemaker Settings With R-wave Detection

Pacemakers require adjustment of the time setting based on a cardiac ejection period. This patented method uses arterial pulse waveform features with a feature from an ECG signal to detect the correct ejection period for pacemaker timing. It provides an accurate and easy way to program a pacemaker.

Measuring Central Pressure with a Brachial Cuff

Non-invasively estimating the heart's pressure and pressure waveform with features related to cardiac function and arterial properties by using a conventional BP cuff inflated to different pressure values. The patent provides a non-invasive, simple, and operator-independent tool to clinically diagnose cardiovascular system and estimate risk of having heart disease which otherwise require an invasive procedure. The method in principle can be implemented in BP cuff devices and improve their capability.

Estimating Central Aortic Pressure from Brachial Cuff Pulse

Non-invasively estimating the heart's pressure and pressure waveform with features related to cardiac function and arterial properties by using a conventional BP cuff inflated to low pressure. The patent provides a non-invasive, simple, and operator-independent tool to clinically diagnose cardiovascular system and estimate risk of having heart disease which otherwise require an invasive procedure. The method in principle can be implemented in BP cuff devices and improve their capability.

Methods for Determining Cardiac Output

Cardiac output is a clinically important parameter in order to assess a patient's cardiac function and assist in cardiac diagnosis. Known cardiac output measurements require an extensive and invasive procedure. This patent provides a simpler method of estimating cardiac output from a non-invasive arterial pulse recording.

Method of Estimating Pulse Wave Velocity

This patented method estimates the "gold standard" arterial stiffness indicator, PWV (pulse waveform velocity), from one single arterial pulse recording on the wrist, arm, or finger. This method has the advantage of measuring PWV from one single pulse instead of the usual two-pulse method that requires multiple sensors' recordings.

Simplified Systolic and Pulse Pressure Method

The more clinically relevant blood pressure (BP) at the heart differs significantly from BP at the upper arm. BP at the heart can only be measured directly through an invasive procedure. This patent provides a simple and non-invasive method of estimating BP at the heart from a non-invasive pulse recording on the wrist.
