Limits on driving depend on many things. These include: 1, 2, 3 ; Any symptoms you may have had, like fainting. ; The cause of your arrhythmia. ; The likelihood that your arrhythmia will happen again. ; If your arrhythmia has been treated successfully.
The electrical signal causes both upper chambers (your atria) to pump blood into your two lower chambers (your ventricles). ; The signal then moves to another group of cells called the atrioventricular (AV) node. The AV node is a wire that helps conduct electricity from the atria to the ventricles. ; The AV node then sends another signal to your ventricles. This makes your ventricles pump blood out of your heart and to the rest of your body. ; Finally, the ventricles relax, and a new signal starts a new heartbeat.

An arrhythmia, like atrial fibrillation, is an abnormal heart rhythm or heartbeat. Some arrhythmias are harmless and may have no noticeable symptoms, while others can be serious or life-threatening.
Heart rhythm disorders (arrhythmias) occur when the heart's electrical system malfunctions. Discover the different types (like atrial fibrillation), causes, symptoms, diagnostic methods, treatment...
Supraventricular arrhythmias: These begin in your atria (your heart’s upper chambers). “Supraventricular” means above your ventricles or lower chambers of your heart. ; Ventricular arrhythmias: These begin in your heart’s ventricles or lower chambers. ; Bradyarrhythmias and junctional rhythms: These can happen because of issues in your heart’s conduction system, such as the sinoatrial (SA) node, atrioventricular (AV) node or His-Purkinje network.
Arrhythmias can be an emergency, or they can be harmless. If you feel something unusual happening with your heartbeat, get medical ...
Ventricular arrhythmias are rhythm disorders that make the lower heart chambers twitch instead of pump. Understand the types, causes and treatment options.
