Cat 5 – Ventricular Tachycardia
Coala has detected ventricular tachycardia (VT) defined as a fast, regular sequence with widened QRS.
Ventricular tachycardia (VT) is a heart rhythm disorder caused by abnormal electrical signals in the lower chambers of the heart (ventricles). When this happens, your heart may not be able to pump enough blood to your body and lungs because the chambers are beating so fast or out of sync with each other that they don't have time to fill properly. The Coala indicates for VT when the R-R interval is shorter than 600 ms and QRS duration larger than 120 ms.
VT may be brief, lasting for only a few seconds, and perhaps not cause any symptoms. Or it can last for much longer and cause symptoms such as dizziness, lightheadedness, palpitations or even loss of consciousness.
In some cases, VT can cause your heart to stop (sudden cardiac arrest), which is a life-threatening medical emergency. This condition usually occurs in people with other heart conditions, such as those who have had a previous heart attack or other structural heart disease (cardiomyopathy).
When the Coala detects this type of condition with related symptoms, emergency medical care should be sought.
