Types of Heart Rhythm
It's just like if there was an extra road on your way home as well as your usual route, so cars can move around faster. When that happens in your heart, it can cause a fast heart rhythm, which doctors call tachycardia. The impulses that control your heart rhythm travel around the heart very quickly, making it beat unusually fast.
Atrial fibrillation (also called AFib or AF) is a quivering or irregular heartbeat (arrhythmia) that can lead to blood clots, stroke, heart failure and other heart-related complications. At least 2.7 million Americans are living with AFib.
Atrial flutter is an abnormality in the beating of the heart. WebMD provides a comprehensive look at the causes, symptoms, diagnosis, and treatment of atrial flutter and atrial fibrillation.
AV nodal reentrant tachycardia (AVNRT), or atrioventricular nodal reentrant tachycardia, is a type of abnormal fast heart rhythm. It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His. AV nodal reentrant tachycardia is the most common regular supraventricular tachycardia.
Paroxysmal supraventricular tachycardia is a heart condition characterized by symptoms like palpitations, chest pressure, lightheadedness, weakness, shortness of breath. PSVT may be treated with medications or an ablation.
Another name for atrial premature complexes is premature atrial contractions. One of the most common symptoms of APCs is heart palpitations or unusual awareness of your heartbeats. Palpitations are heartbeats that are extra fast, extra slow, or irregularly timed.
A premature contraction feels like your heart "skipped a beat." Premature atrial contractions (PACs) start in the upper chambers of the heart (atria). Premature ventricular contractions (PVCs) start in the lower chambers of the heart (ventricles).
If you watch medical dramas, you may have heard TV doctors say someone is in ‘V-tach.” That is the simple and quick way of saying “ventricular tachycardia.” The word “ventricular” refers to your heart’s lower chambers.
