You can count your heart rate. But your pulse can tell you something else: whether the beat is steady. The rhythm, not just the rate.
Most of the time a pulse is regular, like a clock — tick, tick, tick. Sometimes a beat comes early or late, or the spacing wanders. An occasional early or late beat is common. But a pulse that's irregular again and again is worth noticing.
How to check: rest 5 minutes, find your pulse, and instead of only counting, feel the spacing between beats. Is it even? Do it for a full minute, the same time of day, a few days running.
A pulse that's often irregular can be a sign of atrial fibrillation, a common heart rhythm condition. Only a doctor can confirm that, usually with a quick test called an ECG. Because this rhythm can come and go, one steady check doesn't rule it out — so notice the pattern over several days and write it down. If your pulse feels irregular often, or comes with dizziness, breathlessness, or chest discomfort, don't wait — call your doctor.
