When is a Bradyarrhythmia diagnosed?

The contraction of the heart muscle is triggered by an automatic electrical impulse. The impulse is caused by a specialized group of cells located in the right atrium. When the electrical impulse or the conduction pathways, which transmit the impulse across the cardiac muscle are disrupted, the heart rate is either slowed, accelerated, or the rhythm becomes irregular.

This can cause disturbances such as fainting, light-headedness or fatigue. Various tests are often performed, which you may have already undergone, such as electrocardiogram (ECG), 24-hour continuous ECG recording (Holter), and heart rhythm studies via temporary catheters placed inside the heart (electrophysiological test). Depending on the severity of the signs or symptoms, and the outcome of the tests, the implantation of a pacemaker may be recommended.
