What are the Symptoms of Sinus Bradycardia?
October 12, 2023 | by Sravani Pathakamuri | Posted in FAQ's
Sinus bradycardia is a medical condition characterized by an abnormally slow heart rate, typically below 60 beats per minute. It occurs when the heart’s natural pacemaker, the sinoatrial (SA) node, generates electrical signals at a slower rate than normal. While sinus bradycardia can be a normal variation in some athletes or during deep sleep, it can also be a sign of an underlying health issue.
Symptoms of sinus bradycardia can manifest in various ways, with their severity depending on the individual and the degree of bradycardia. One of the common symptoms is fatigue or a general feeling of tiredness. Individuals with sinus bradycardia often experience a lack of energy or stamina, making it difficult to perform routine activities.
Dizziness or lightheadedness is another symptom. When the heart beats too slowly, it may not pump enough blood to meet the body’s needs, resulting in reduced blood flow to the brain. This can cause dizziness or a sensation of feeling lightheaded or woozy, especially upon standing or sudden position changes.
Shortness of breath is a symptom that can occur with sinus bradycardia. Insufficient blood flow due to a slow heart rate can lead to inadequate oxygen supply to the body, causing breathlessness even during mild exertion or at rest.
In some cases, sinus bradycardia may cause chest pain or discomfort. The heart may struggle to pump enough blood to meet the body’s demands, causing discomfort or a feeling of pressure in the chest. This symptom should be taken seriously, as it may indicate a more severe underlying condition.
Fainting or near-fainting episodes (presyncope) can be a result of sinus bradycardia. The brain may not receive enough blood and oxygen during episodes of bradycardia, leading to temporary loss of consciousness or near-fainting spells.
It’s essential to note that some individuals with sinus bradycardia may not experience noticeable symptoms, especially if the heart rate remains within a mildly slower range and does not significantly impact blood flow and oxygen delivery.
If you suspect you have sinus bradycardia or are experiencing any of these symptoms, it’s crucial to seek medical attention. A thorough evaluation by a healthcare professional can help determine the cause of the slow heart rate and guide appropriate management, ensuring your overall heart health and well-being.
