Signs and Symptoms of Heart Block
Syncope and Dizziness in Heart Block
One of the most common symptoms of heart block is syncope, or fainting, which occurs due to a sudden drop in heart rate and blood pressure, leading to reduced blood flow to the brain. This symptom is frequently observed in patients with complete heart block, as noted in several studies . Dizziness is another prevalent symptom, often accompanying syncope, as the brain receives insufficient oxygen.
Palpitations and Effort Intolerance
Patients with heart block may experience palpitations, which are sensations of irregular or forceful heartbeats. This symptom is particularly noted in cases of complete heart block associated with various underlying conditions such as coronary artery disease and hypertensive heart disease. Effort intolerance, or the inability to perform physical activities without experiencing fatigue or shortness of breath, is also a significant symptom, especially in those with radiation-induced heart block.
Chest Pain and Anginal Pain
Chest pain, including anginal pain, is another critical symptom of heart block. This pain can be a result of underlying coronary artery disease, which is often associated with complete heart block. In some cases, chest pain may mimic symptoms of myocardial infarction, making it essential to differentiate between the two conditions.
Bradycardia and Abnormal Heart Rhythms
Bradycardia, or a slower than normal heart rate, is a hallmark of heart block. This condition can lead to various degrees of atrioventricular block, as seen in patients with complete heart block. Abnormal heart rhythms, including third-degree atrioventricular block and bundle branch blocks, are also common findings in electrocardiograms of affected patients .
Congestive Heart Failure and Fatigue
Congestive heart failure, characterized by the heart's inability to pump blood effectively, can occur in patients with severe heart block. This condition leads to symptoms such as fatigue, shortness of breath, and swelling in the legs and ankles. Fatigue is a common symptom due to the heart's reduced efficiency in circulating blood throughout the body.
Additional Symptoms: Sweating, Nausea, and Vomiting
Other symptoms that may accompany heart block include sweating, nausea, and vomiting. These symptoms are often related to the body's response to reduced cardiac output and can be particularly distressing for patients.
Conclusion
Heart block presents with a variety of signs and symptoms, including syncope, dizziness, palpitations, chest pain, bradycardia, congestive heart failure, and fatigue. Recognizing these symptoms is crucial for timely diagnosis and management, as heart block can significantly impact a patient's quality of life and overall health.
