A Holter monitor measures what aspect of the heart?

Holter monitoring is all about recording the heart’s electrical activity over time to track its rhythm. By continuously capturing an ECG for 24 to 48 hours, it reveals how regularly the heart beats, how quickly or slowly it runs, and whether there are irregular pauses or episodes of arrhythmia that come and go. This focus on electrical timing and pattern is why rhythm is the right choice. Other concepts like capacity, strength, or pressure aren’t what a Holter measures. Capacity or strength relates to how much blood the heart can pump or how forcefully it contracts, which are studied with imaging or invasive tests rather than continuous ECG monitoring. Pressure refers to blood pressure, which is obtained with a cuff or arterial line, not a Holter device.
