The early symptoms of heart block can vary, but commonly include dizziness, fainting, a feeling of skipped heartbeats, shortness of breath, nausea, and severe fatigue.
Heart block, also known as atrioventricular (AV) block, occurs when the electrical signals that control your heartbeat are delayed or blocked as they travel from the upper chambers (atria) to the lower chambers (ventricles) of your heart. This disruption can lead to a slower or irregular heartbeat, resulting in the symptoms listed below.
Here's a breakdown of common early symptoms:
-
Dizziness: Reduced blood flow to the brain due to a slower heart rate can cause lightheadedness or dizziness.
-
Fainting (Syncope): In more severe cases, the reduced blood flow can lead to a temporary loss of consciousness.
-
Feeling of Skipped Heartbeats: Some individuals may perceive a pause or irregularity in their heartbeat. This sensation can be alarming and warrants medical evaluation.
-
Trouble Breathing or Shortness of Breath (Dyspnea): Inefficient pumping of blood can lead to fluid buildup in the lungs, causing shortness of breath, especially during activity.
-
Nausea: Reduced blood flow may affect the digestive system, leading to feelings of nausea.
-
Severe Tiredness (Fatigue): A slower heart rate means that the body's tissues and organs might not receive enough oxygen, resulting in unexplained fatigue.
It's important to note that these symptoms can be subtle and may be attributed to other causes. If you experience any of these symptoms, especially if they are new or worsening, you should consult with a healthcare professional for proper diagnosis and management. Early detection and treatment of heart block can help prevent serious complications.
