Introduction

Heart function data can come in many forms including ECG (electrocardiogram) traces and pressure changes. The aim of collecting this data is to monitor the activity of the heart and identify any issues pertaining to the circulatory system.

What are ECG traces

ECG traces are electrical changes recorded at the skin level using electrodes. Heart beats are recorded, including the stages between them to visualise full cardiac cycle patterns over time.

The largest signal is given by the ventricular systole, with other smaller signals given by the surrounding heart cycle events. The different signals have wave terms, such as the P wave and the T wave. The spacing and duration of the signals can indicate the speed of the heart beats and their regularity, which can be used to asses various pathologies such as…
