Supraventricular tachycardia is suspected when a doctor or nurse counts a very rapid heart rate (>200) during an attack . To confirm the diagnosis, your child’s pediatrician might perform an electrocardiogram (ECG – also known as EKG). An ECG is a test which records the electrical activity of the heart.
Read moreWhat is difference between arrhythmia and atrial fibrillation?
An arrhythmia is when the heart beats too slowly, too fast, or in an irregular way. When a person has AFib, the normal beating in the upper chambers of the heart (the two atria) is irregular, and blood doesn’t flow as well as it should from the atria to the lower chambers of the heart (the two ventricles).

Ventricular fibrillation is most commonly caused by the following:
Read moreWhat causes atrial and ventricular fibrillation?
Atrial fibrillation and ventricular fibrillation are caused by similar problems with the heart , but they are not the same type of problem. Electrical impulses generated within the heart tissue cause both heart conditions, but the electrical impulses arise in different areas of the heart.
Read moreWhich is more serious atrial or ventricular fibrillation?
Ventricular fibrillation is more serious than atrial fibrillation . Ventricular fibrillation frequently results in loss of consciousness and death, because ventricular arrhythmias are more likely to interrupt the pumping of blood, or undermine the heart’s ability to supply the body with oxygen-rich blood.
Read moreCan PVCs cause sudden death?
1 Introduction. A premature ventricular complex (PVC) is an early depolarization of ventricular myocardium. PVCs are common findings on electrocardiography (ECG) in the general population and are associated with structural heart disease and increased risk of sudden cardiac death .
Read moreWhen should I worry about PVCs?
PVCs become more of a concern if they happen frequently. “If more than 10% to 15% of a person’s heartbeats in 24 hours are PVCs, that’s excessive ,” Bentz said. The more PVCs occur, the more they can potentially cause a condition called cardiomyopathy (a weakened heart muscle).
