Is a Heart Rate of Around 90 Normal?

A normal resting heart rate typically ranges between 60 and 100 beats per minute (BPM). A heart rate of approximately 90 BPM falls within this healthy range for most individuals. However, it's important to consider the context in which this heart rate occurs and the overall health of the person.

Understanding Heart Rhythm and Origin

When evaluating a heart rate of 90 BPM, it's essential to determine the type of heart rhythm involved. If the rhythm is sinus in origin—which means the heart's natural pacemaker is controlling the beat—then a rate of 90 BPM is perfectly normal and not a cause for concern.

However, if the heart rate originates from an abnormal area of the heart, such as the atrioventricular (AV) junction or the ventricles, then a rate above 90 BPM may indicate an irregular or pathological rhythm. In these cases, even a seemingly normal BPM could signal an underlying issue with the heart's electrical system.

Consideration for Individuals with Naturally Low Heart Rates

For individuals who typically have a lower resting heart rate—such as athletes or those who maintain a high level of physical fitness—a sudden increase to 90 BPM or higher may be worth further investigation. If this change is accompanied by symptoms like fever, palpitations, fatigue, or shortness of breath, it could indicate an underlying health condition that needs medical attention.

When to Seek Medical Advice

While a heart rate of 90 BPM is generally considered normal, it's wise to consult a healthcare professional if you experience any unusual symptoms or if this heart rate is out of the ordinary for you. A doctor can perform an electrocardiogram (EKG) or other tests to ensure your heart rhythm is truly sinus and to rule out any potential cardiac or systemic issues.
