I'm a bit concerned about my husband's heart rate. His watch is recording a high pulse rate, sometimes hitting numbers as high as 160, 120, or 150, a few times a day. He doesn't have any symptoms, and his blood pressure is normal. We've done TMT, ECG, and echo tests, and they all came back normal. What could be causing these spikes?
It's good that all the cardiac tests have come back normal. A high pulse rate without any other symptoms can sometimes be due to factors such as stress, anxiety, dehydration, or even certain medications. However, since your husband is not experiencing any symptoms, it may be worth monitoring his pulse rate over a period of time to see if there are any patterns or triggers. In some cases, a high pulse rate can be a sign of an underlying condition such as an overactive thyroid gland or an arrhythmia. If the high pulse rate continues or if there are any other concerning symptoms, further evaluation by a healthcare provider may be necessary. In the meantime, it may be helpful to ensure that your husband stays hydrated, gets adequate rest, and manages stress levels.
