Symptoms of a Heart Block
Introduction to Heart Block Symptoms
Heart block, also known as atrioventricular (AV) block, occurs when the electrical signals that control the heartbeat are partially or completely blocked. This condition can lead to a variety of symptoms, which can vary depending on the severity and type of heart block.
Common Symptoms of Complete Heart Block
Syncope and Dizziness
One of the most common symptoms of complete heart block is syncope, or fainting, which occurs due to a sudden drop in blood flow to the brain. This symptom is frequently reported in patients with complete heart block, including those with radiation-induced heart block and congenital complete heart block . Dizziness and vertigo are also common, as the brain receives insufficient blood flow.
Palpitations and Irregular Heartbeat
Patients with complete heart block often experience palpitations, which are sensations of a rapid, fluttering, or pounding heart. This symptom is noted across various studies, indicating its prevalence among heart block patients . The irregular heartbeat, or bradycardia, is a direct result of the disrupted electrical signals between the atria and ventricles.
Chest Pain and Discomfort
Chest pain is another significant symptom associated with heart block. This pain can be severe and is often accompanied by other symptoms such as breathlessness and excessive sweating . In some cases, the chest pain may resemble angina but with atypical qualities, such as abrupt onset and localized pain without radiation.
Additional Symptoms and Complications
Breathlessness and Fatigue
Breathlessness, or dyspnea, is a common symptom in heart block patients, often exacerbated by physical exertion. This symptom is frequently reported alongside fatigue, as the heart's reduced efficiency leads to decreased oxygen delivery to the body .
Congestive Heart Failure
In more severe cases, heart block can lead to congestive heart failure, where the heart is unable to pump blood effectively. Symptoms of congestive heart failure include swelling in the legs, ankles, and feet, as well as persistent coughing or wheezing.
Anxiety and Sweating
Patients with heart block may also experience anxiety and excessive sweating, particularly during episodes of chest pain or palpitations. These symptoms are part of the body's stress response to the reduced cardiac output and irregular heart rhythms .
Conclusion
Heart block presents with a range of symptoms, from syncope and palpitations to chest pain and breathlessness. Recognizing these symptoms early is crucial for timely diagnosis and treatment, which can significantly improve patient outcomes. If you experience any of these symptoms, it is important to seek medical attention promptly.
