Is Sinus Arrhythmia Harmful?
Sinus arrhythmia, in all its three types, is considered to be harmless. Although some young and healthy individuals may experience symptoms, there are no serious side effects associated with it. If the underlying cause of an abnormal increase or decrease in heart rate is known, both sinus tachycardia and bradycardia are not considered dangerous. However, when sinus arrhythmia occurs in the elderly without any identifiable reason, it may be an indication of more serious underlying health issues.
Symptoms of Sinus Arrhythmia
Sinus arrhythmia is a condition that often goes unnoticed due to its mild symptoms. However, there are a few signs that may indicate its presence. The most prominent symptom is an irregular heart rate. When examining the pulse, a healthcare professional may observe slight variations in the rhythm during inhalation and exhalation. Furthermore, individuals with sinus arrhythmia may experience additional symptoms such as lightheadedness or shortness of breath, which can be accompanied by either a slow or fast pulse.
