Anxiety with a heart rate of 120 beats per minute?


I have anxiety disorder, and a few months ago, I visited a clinic for the first time to have my blood pressure measured.
The result showed a heart rate of 120, which I am unsure if it was due to my nervousness.
At that moment, the doctor asked if I felt unwell, but I actually did not.
He suggested that I observe it further.
When I measure my heart rate at home, it ranges from 60 to 100.
I am unsure if that instance of 120 was normal.
Is it normal for my heart rate to be 120 when I am anxious? Additionally, at that time, whenever I read health articles online, I felt that I had similar symptoms and became afraid of having a serious illness.
The more I read, the more scared I became, but when I compared my symptoms, they were actually different.
However, I still felt frightened just by reading.

Many factors in daily life can contribute to this condition, such as emotions, stress, irregular sleep patterns, or excessive intake of caffeinated beverages.
It is recommended to adjust your lifestyle and engage in regular exercise.
However, if symptoms persist, it is advisable to visit a hospital for an electrocardiogram (ECG) examination.

More Info


Experiencing a heart rate of 120 beats per minute (bpm) during moments of anxiety can indeed be a common physiological response. When you feel anxious or stressed, your body activates the "fight or flight" response, which is part of the sympathetic nervous system. This response triggers the release of stress hormones like adrenaline, leading to an increase in heart rate, blood pressure, and energy supplies. Therefore, a heart rate of 120 bpm in a state of anxiety is not unusual, especially if you were feeling particularly tense or nervous at that moment.

In general, a normal resting heart rate for adults ranges from 60 to 100 bpm. Factors such as physical fitness, emotional state, and even the time of day can influence this rate. For instance, athletes often have lower resting heart rates due to their higher cardiovascular efficiency. Your observation of a heart rate between 60 and 100 bpm at home indicates that your heart is functioning normally during periods of calm.

However, it is essential to recognize that anxiety can lead to fluctuations in heart rate. When you experience anxiety, your heart rate can spike significantly, as you noted with the 120 bpm reading. This increase is typically temporary and should return to your normal range once the anxiety subsides. If you do not experience any other symptoms, such as chest pain, dizziness, or shortness of breath, this response is generally considered benign.

It's also worth noting that your tendency to search for health information online can sometimes exacerbate anxiety. The phenomenon of "cyberchondria," where individuals become increasingly anxious about their health after researching symptoms online, is well-documented. It’s crucial to approach health information critically and consult healthcare professionals for accurate assessments rather than relying solely on online resources.

If you find that your anxiety and heart rate fluctuations are persistent or worsening, it may be beneficial to seek further evaluation from a healthcare provider. They can help determine if there are underlying issues contributing to your symptoms, such as autonomic nervous system dysfunction or other medical conditions. In some cases, a referral to a mental health professional may be warranted to address anxiety management strategies.

In summary, a heart rate of 120 bpm during anxiety is generally a normal physiological response. However, if you experience ongoing anxiety or heart rate irregularities, it is advisable to consult with a healthcare professional for a comprehensive evaluation and tailored management plan. Regular exercise, proper sleep hygiene, and stress management techniques can also be beneficial in managing anxiety and maintaining a healthy heart rate.
