What are the normal variations in resting ECG parameters among healthy individuals aged 18 to 40 years?
This study establishes normal reference ranges for standard resting ECG parameters in healthy young adults aged 18 to 40 years.
SK et al. (2014) conducted a cross-sectional in Healthy (n=150). Resting Electrocardiogram (ECG) was evaluated on Normal variations in ECG parameters (QRS duration, QRS axis, QRS voltage, QTc interval, T wave voltage). In 150 healthy young adults, resting ECG showed a mean QRS duration of 0.064 seconds, mean QRS axis of 52.8 degrees, mean QRS voltage of 1.14 mV, and mean QTc interval of 0.39 seconds.
