Electronic electrocardiogram calipers

A medical device, comprising:

• a display configured to present a graphical representation of an electrocardiogram (ECG) of a patient and repeated calipers overlaid on the graphical representation of the ECG, the ECG being detected by a measurement circuit;
• a processor configured to:
• identify a movement of a touch from a user on the display, the touch being detected by a sensor and at a position of a tip of a caliper among the repeated calipers;
• in response to identifying the movement of the touch from the user, cause the display to move the repeated calipers from first positions to second positions, an interval between the repeated calipers at the first positions being different than an interval between the repeated calipers at the second positions.

A method for patient monitoring, the method comprising:

• presenting, by a display, a graphical representation of an electrocardiogram (ECG) and repeated calipers overlaid on the graphical representation of the ECG, the ECG being detected by a measurement circuit;
• detecting, by a sensor, a touch from a user on the display at a position of a tip of a caliper among repeated calipers;
• identifying movement of the touch from the user;
• and
• in response to identifying the movement of the touch from the user, moving the repeated calipers from first positions to second positions, an interval between the repeated calipers at the first positions being different than an interval between the repeated calipers at the second positions.
