WPW Accessory Pathway Shortest RR

Assess WPW arrhythmic risk using shortest pre-excited RR interval during AF. Shortest R-R <250ms is a high-risk feature associated with potential VF via accessory pathway.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Assess WPW arrhythmic risk using shortest pre-excited RR interval during AF. Shortest R-R <250ms is a high-risk feature associated with potential VF via accessory pathway

Each component has a specific meaning:

  • Shortest pre-excited RR interval during AF — The shortest pre-excited rr interval during af recorded for the scenario being assessed.

Note: Interpret the wpw shortest rr interval result against the thresholds and context described above.

How to Use

Enter the shortest pre-excited RR interval during AF for the scenario you are assessing. Assess WPW arrhythmic risk using shortest pre-excited RR interval during AF. Shortest R-R <250ms is a high-risk feature associated with potential VF via accessory pathway. Use the wpw shortest rr interval result to inform your calculation.
