AFib Heart Rate Calculator
This calculator helps you estimate your heart rate during an Atrial Fibrillation (AFib) episode. AFib is a condition where the upper chambers of the heart (atria) beat irregularly and often rapidly. This can lead to a faster and irregular pulse. Remember, this calculator is for informational purposes only and does not substitute professional medical advice. If you suspect you are experiencing AFib, please consult a healthcare provider immediately.
Resting Heart Rate (bpm):
Activity Level (during episode):
Resting/Sitting
Light Activity (walking slowly)
Moderate Activity (brisk walking)
Strenuous Activity (exercise)
Calculate Estimated AFib Heart Rate
function calculateAfibHeartRate() {
var restingRate = parseFloat(document.getElementById("restingHeartRate").value);
var activityMultiplier = parseFloat(document.getElementById("activityLevel").value);
var resultDiv = document.getElementById("result");
resultDiv.innerHTML = ""; // Clear previous result
if (isNaN(restingRate) || restingRate maxAfibRate) {
var temp = minAfibRate;
minAfibRate = maxAfibRate;
maxAfibRate = temp;
}
resultDiv.innerHTML = "Estimated AFib Heart Rate Range: " + minAfibRate.toFixed(0) + " – " + maxAfibRate.toFixed(0) + " bpm (irregular)";
