Key result

A proposed QRS detection algorithm utilizing low pass, difference, and moving average filters achieved sensitivities ranging from 85% to 91% in noisy ECG signals.

Why the study?

ECG signals are typically affected by artifacts requiring manual assessment or reference signals, prompting the need for automatic recognition of QRS complexes.

Population

Three cardiogram patterns, each consisting of 20 samples of 20 seconds duration, distorted by various types…

Overview

Proposed QRS algorithm may support automated ECG analysis; leaves open prospective validation before clinical adoption.

Structured PICO

P
Population
Three 20-second cardiogram signals distorted by various types of noise used to validate a QRS detection algorithm.
I
Intervention
Automatic QRS detection algorithm using low pass, difference, and moving average filters followed by an adaptive threshold function.
O
Outcome
Sensitivity of QRS complex detection

A proposed less computational algorithm using a series of filters and an adaptive threshold function achieved 85-91% sensitivity in detecting QRS complexes in noisy ECG signals.

Limitations

  • High-frequency EMG noise and patient movement can distort boundaries and lead to omission of beats, requiring an adaptive threshold function.
  • Approximate definition of boundaries can be challenging when distorted by high-frequency EMG noise and patient movement noise, leading to omission of several beats.
