What is Junctional Tachycardia?.
Junctional tachycardia is an unusually fast heart rhythm originating around the atrioventricular (AV) junction, a structure between the atria and ventricles of the heart that houses the AV node, an important part of the heart’s natural pacemaker system. This particular heart rhythm is part of a larger family of rapid heart rhythms known as supraventricular tachycardias, so named because they originate above the ventricles of the heart. A number of issues can lead to junctional tachycardia in a patient.
A doctor can identify tachycardia simply by feeling a patient’s pulse or listening to the heart and noting that the heartbeat is faster than it should be. To determine the type of tachycardia involved, it is necessary to conduct an electrocardiogram, where the electrical impulses from the heart are measured. These impulses form distinctive patterns on the ECG readout and the shape of the pattern can be used to identify the source of an abnormal heart rhythm.
Some patients naturally have a mild junctional tachycardia and they may not require any medical intervention, although the abnormal heart rhythm will be noted in the patient’s chart so it will not be a cause for alarm in the future. In other patients, the heart rhythm is a cause for concern, indicating a problem with the way the heart regulates itself. M
