Systems and methods for classifying ECG data
A computer-implemented method for processing ECG data may include: receiving, over an electronic network, ECG data, wherein the ECG data represents a plurality of heartbeats; analyzing the ECG data, by at least one processor, to determine whether each of the plurality of heartbeats is a normal heartbeat or an abnormal heartbeat; associating, by the at least one processor, each of the abnormal heartbeats with either only one of a plurality of existing templates or a new template; receiving, from a user, input related to each new template, wherein the input includes either: a) a confirmation that the new template represents an abnormal heartbeat, or b) a reclassification of the new template as representing a normal heartbeat or a different abnormal heartbeat; and in response to the user input, updating, by the at least one processor, a label of each of the heartbeats associated with each confirmed new template and each of the heartbeats associated with each reclassified new template. The ECG data may be received from a portable monitor configured to be carried on a patient's body.
1. A computer-implemented method for classifying ECG data, comprising:
classifying, using at least one processor, heartbeats in ECG data as (i) normal heartbeats, (ii) abnormal heartbeats associated with one or more preexisting templates, or (iii) abnormal heartbeats associated with one or more new templates;
receiving user input related to each new template of the one or more new templates after the classifying step, wherein the input includes either (a) a confirmation that the new template represents an abnormal heartbeat, (b) a reclassification of the new template as a normal heartbeat, or (c) a reclassification of the new template as representing an abnormal heartbeat different than the abnormal heartbeat from the classifying step; and
after receiving the user input, determining, by the at least one processor, a total number of abnormal heartbeats as a sum of the heartbeats associated with (d) the one or more preexisting templates and (e) the one or more new templates representing an abnormal heartbeat.
2. The method of claim 1 , wherein the method does not include repeating the classifying step between the step of receiving user input and the step of determining the total number of abnormal heartbeats.
3. The method of claim 1 , wherein the classifying step includes comparing each heartbeat in the ECG data to at least one of the one or more preexisting templates.
4. The method of claim 3 , wherein the classifying step further includes creating a new template of the one or more new templates if a characteristic of an abnormal heartbeat in the ECG data differs from the characteristic of each preexisting template of the one or more preexisting templates.
5. The method of claim 1 , further including receiving the ECG data.
6. The method of claim 5 , wherein the receiving step includes wirelessly receiving the ECG data from a portable device configured to be carried on a patient's body.
7. The method of claim 1 , wherein the abnormal heartbeats represent arrhythmias.
8. The method of claim 1 , wherein the abnormal heartbeats represent premature ventricular contractions.
9. The method of claim 1 , further including displaying the total number of abnormal heartbeats on a display device.
10. A system for classifying ECG data, comprising:
a data storage device that stores instructions for processing ECG data; and
one or more processors configured to execute the instructions to perform a method including:
classifying, using at least one processor, heartbeats in ECG data as (i) normal heartbeats, (ii) abnormal heartbeats associated with one or more preexisting templates, or (iii) abnormal heartbeats associated with one or more new templates;
receiving user input related to each new template of the one or more new templates after the classifying step, wherein the input includes either (a) a confirmation that the new template represents an abnormal heartbeat, (b) a reclassification of the new template as a normal heartbeat, or (c) a reclassification of the new template as representing an abnormal heartbeat different than the abnormal heartbeat from the classifying step; and
after receiving the user input, determining, by the at least one processor, a total number of abnormal heartbeats as a sum of the heartbeats associated with (d) the one or more preexisting templates and (e) the one or more new templates representing an abnormal heartbeat.
11. The system of claim 10 , wherein the method performed by the one or more processors does not include repeating the classifying step between the step of receiving user input and the step of determining the total number of abnormal heartbeats.
12. The system of claim 10 , wherein the classifying step includes comparing each heartbeat in the ECG data to at least one of the one or more preexisting templates.
13. The system of claim 12 , wherein the classifying step further includes creating a new template of the one or more new templates if a characteristic of an abnormal heartbeat in the ECG data differs from the characteristic of each preexisting template of the one or more preexisting templates.
14. The system of claim 10 , further including a wireless receiver, and the method performed by the one or more processors further includes wirelessly receiving the ECG data from a portable device configured to be carried on a patient's body.
15. The system of claim 10 , wherein the abnormal heartbeats represent arrhythmias.
16. A non-transitory computer-readable medium storing instructions that, when executed by a computer, cause the computer to perform a method for classifying ECG data, the method including:
classifying, using at least one processor, heartbeats in ECG data as (i) normal heartbeats, (ii) abnormal heartbeats associated with one or more preexisting templates, or (iii) abnormal heartbeats associated with one or more new templates;
receiving user input related to each new template of the one or more new templates after the classifying step, wherein the input includes either (a) a confirmation that the new template represents an abnormal heartbeat, (b) a reclassification of the new template as a normal heartbeat, or (c) a reclassification of the new template as representing an abnormal heartbeat different than the abnormal heartbeat from the classifying step; and
after receiving the user input, determining, by the at least one processor, a total number of abnormal heartbeats as a sum of the heartbeats associated with (d) the one or more preexisting templates and (e) the one or more new templates representing an abnormal heartbeat.
17. The computer-readable medium of claim 16 , wherein the method does not include repeating the classifying step between the step of receiving user input and the step of determining the total number of abnormal heartbeats.
18. The computer-readable medium of claim 16 , wherein the classifying step includes comparing each heartbeat in the ECG data to at least one of the one or more preexisting templates.
19. The computer-readable medium of claim 18 , wherein the classifying step further includes creating a new template of the one or more new templates if a characteristic of an abnormal heartbeat in the ECG data differs from the characteristic of each preexisting template of the one or more preexisting templates.
20. The computer-readable medium of claim 16 , wherein the method further includes wirelessly receiving the ECG data from a portable device configured to be carried on a patient's body.
