1. A method of conditionally combining photoplethysmography (PPG) measurements comprising:
- obtaining PPG measurements from a group of contiguous PPG sensors located on a toilet seat;
combining the PPG measurements into one or more conditional combinations based on timing data or signal-to-noise ratio data corresponding to each of the PPG measurements; and
using the one or more conditional combinations to determine a cardiac function of a toilet user.

Abstract
A synthetic aperture photoplethysmography (PPG) sensor is disclosed. A group or matrix of contiguous PPG sensors located on a toilet seat are conditionally combined based on sensor measurements. Conditional combinations may be based on timing data and signal-to-noise ratio data of each of the PPG measurements. Measurements associated with the conditional combinations are then used to determine a cardiac function of a toilet user.
