What are problems with the conducting system of the heart?

Problems with the conducting system of the heart can lead to arrhythmias, which are irregular heartbeats that can disrupt normal blood flow. Conditions such as atrioventricular (AV) block or bundle branch block result from impaired electrical signals, potentially causing symptoms like dizziness, fatigue, or fainting. Additionally, issues like sick sinus syndrome can cause bradycardia or tachycardia, affecting the heart's ability to maintain an adequate rhythm. These disorders may require medical intervention, including medications or the implantation of a pacemaker.
