ECG Irregular Rhythm Heart Rate Calculator

This calculator helps estimate heart rate from an Electrocardiogram (ECG) when the heart rhythm is irregular. For regular rhythms, a simpler calculation is often used. However, for irregular rhythms, we need to consider the average R-R interval or count the number of QRS complexes over a longer period. This calculator uses the common method of counting QRS complexes within a specific duration, typically 6 seconds, and extrapolating to a minute. This method provides a reasonable estimate for most clinical scenarios.

How it works:

  1. Locate a 6-second strip on the ECG tracing. This is usually marked by 'R-R' intervals at the top of the paper or by timing marks.
  2. Count the number of QRS complexes (the tall, narrow spikes) within that 6-second strip.
  3. Multiply the number of QRS complexes by 10. This will give you the estimated heart rate in beats per minute (BPM).
