Symptoms
Sinus arrhythmia does not cause any cardiovascular signs. In fact, many people might never have any symptoms, and the condition would never be diagnosed. If you can read the pulse, then it is possible to notice a slight change in the pulse rate when you breathe in and out. Nevertheless, the variation might be so subtle that only a machine can tell the differences. Make sure to visit your healthcare provider when you feel a skipping heartbeat or heart palpitations. These signs are quite dangerous and might indicate a more serious condition. [4]
