![]() What happens if my child has palpitations? Some children have extra connections of the heart's electrical system that can lead to tachycardia in an abnormal fashion. This is called sinus tachycardia and is normal. Some children, particularly young adults, are aware of rapid heartbeats that are due to the speeding up of the heart that naturally occurs in response to exercise or stress. In addition to single extra beats, runs of fast rhythms, or tachycardias, can be sensed as palpitations. Sometimes things that speed up your heart rate, like caffeine or stress, can make these premature beats occur more often. People with normal hearts can have these early beats often and not realize they are having them, while others are very aware of every extra beat of their heart. These are called premature ventricular contractions or ventricular premature beats. Sometimes these early beats can come from the ventricles or lower chambers of the heart. These are referred to as premature or early beats.Įarly beats that start in the atrium or upper chambers of the heart are usually called premature atrial contractions (PACs) or atrial premature beats. Sometimes, other areas of the heart can send signals that can activate the electrical system earlier than the sinus node. The sinus node is the natural pacemaker of the heart and usually sends signals at regular intervals to the rest of the conduction system. The heart has its own electrical system that organizes the activity of the four pumping chambers. Premature Atrial and Ventricular Contractions Palpitations refer to the sensation of an abnormal heart rhythm, commonly, the heart “racing,” “fluttering” or “skipping a beat.” People use the term “palpitations” for a variety of symptoms. ![]()
