1. A system for detecting a heartbeat with optimal characteristics for an electrophysiological (EP) mapping system that improves cardiac mapping annotations, the system comprising:
a memory;
a sensor; and
one or more processors communicatively coupled to the memory and the sensor, wherein the one or more processors are collectively configured to:
receive, from the sensor, a first heartbeat at an identified cardiac spatial location including first attribute information corresponding to the first heartbeat;
receive, from the sensor, a second heartbeat at the identified cardiac spatial location including a second attribute information corresponding to the second heartbeat;
perform a comparison of the first attribute information with the second attribute information, wherein the comparison includes comparing one or more of heart beat noise, local activation time (LAT), late potential, fractionation or body surface activation during a heart beat; and
determine a selected heartbeat from the first heartbeat and the second heartbeat based on the comparison, wherein the selected heartbeat is utilized in the cardiac mapping annotations.
