- feeling that your heart is beating too hard or fast,
- having shortness of breath during rest/mild exertion, when lying at or during
the night,
- having a known heart murmur,
- having swollen ankles.
Exercising while experiencing any of these symptoms might increase the risk of heart
problems.
- It is important to always listen to your body rst, instead of only relying upon
measurements that the watch provides.
- If you are taking medicines that lower your maximum heart rate (e.g. for high blood
pressure), consult your doctor. Ask your doctor what your target heart rate zone should be.
