A heart rate can be considered dangerous if it falls outside of the normal range, which is generally between 60 and 100 beats per minute for adults. However, what is considered a dangerous heart rate can vary depending on the individual’s age, medical condition, and activity level. In general, a heart rate that is consistently too high (tachycardia) or too low (bradycardia) can be a cause for concern and should be evaluated by a healthcare professional.
Some general guidelines for dangerous heart rates are:
- Bradycardia: a heart rate below 60 beats per minute in adults can be considered dangerous, especially if it causes symptoms such as dizziness, fainting, or shortness of breath.
- Tachycardia: a heart rate above 100 beats per minute at rest or during normal activity can be dangerous, especially if it is sustained for a prolonged period of time or causes symptoms such as chest pain, shortness of breath, or lightheadedness.
However, it’s important to remember that individual circumstances can affect what is considered a dangerous heart rate, so it’s always a good idea to consult a healthcare professional if you have concerns about your heart rate.
