Doctors Near You for Bradycardia in Newcastle

Bradycardia is a condition characterized by an abnormally slow heart rate, typically defined as a resting heart rate below 60 beats per minute in adults. While bradycardia can be a normal physiological response in well-trained athletes or during sleep, it may also indicate an underlying health issue if it occurs at other times or is accompanied by symptoms. The causes of bradycardia are varied. It can be a result of intrinsic problems with the heart's electrical system, such as sick sinus syndrome or atrioventricular (AV) block, where the heart's natural pacemaker or the electrical pathways that transmit signals to the heart are impaired. Other causes include certain medications, particularly those that affect heart rate like beta-blockers or calcium channel blockers. Additionally, bradycardia can be associated with conditions like hypothyroidism, electrolyte imbalances, or myocardial infarction (heart attack). In some cases, bradycardia may occur in response to increased vagal tone or during periods of significant rest or relaxation. Symptoms of bradycardia can vary depending on the severity of the condition and how well the body adapts to the slow heart rate. Common symptoms include dizziness, fatigue, shortness of breath, chest pain, and fainting. In severe cases, bradycardia can lead to more serious complications such as heart failure or sudden cardiac arrest. Treatment for bradycardia depends on its cause and severity. If bradycardia is asymptomatic and not causing any complications, it may not require treatment. However, if it leads to symptoms or is associated with significant health issues, treatment options may include adjusting or discontinuing medications that contribute to the condition. In cases where bradycardia is due to an underlying condition, treating that condition can help manage the heart rate. For more severe cases, particularly if bradycardia is symptomatic and persistent, a pacemaker may be implanted to help regulate and maintain an appropriate heart rate. Proper diagnosis and management of bradycardia involve a thorough evaluation by a healthcare provider, which may include an electrocardiogram (ECG) or other diagnostic tests to assess heart function and rhythm. Addressing the root cause and tailoring treatment to individual needs are crucial for effective management and prevention of complications.
