Atrial tachycardia is a type of heart rhythm problem in which the heart 's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers ( atria) of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity .
Atrial flutter ( AFL) is a common abnormal heart rhythm that starts in the atrial chambers of the heart. [1] When it first occurs, it is usually associated with a fast heart rate and is classified as a type of supraventricular tachycardia. [2] Atrial flutter is characterized by a sudden-onset (usually) regular abnormal heart rhythm on an ...
Tachycardia-induced cardiomyopathy. Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure. [1] [5] People with TIC may have symptoms associated with heart failure (e.g ...
Medications, medical procedures, surgery [5] Frequency. ~3% [6] [7] [8] Supraventricular tachycardia ( SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. [2] This is in contrast to the other group of fast heart rhythms – ventricular tachycardia, which start within the lower chambers of the heart. [2]
Paroxysmal tachycardia. Other names. Bouveret-Hoffmann syndrome. Specialty. Cardiology. Paroxysmal tachycardia is a form of tachycardia which begins and ends in an acute (or paroxysmal) manner. It is also known as "Bouveret-Hoffmann syndrome". [1] [2] [3]
Premature atrial contraction ( PAC ), also known as atrial premature complexes ( APC) or atrial premature beats ( APB ), are a common cardiac dysrhythmia characterized by premature heartbeats originating in the atria. While the sinoatrial node typically regulates the heartbeat during normal sinus rhythm, PACs occur when another region of the ...
Multifocal (or multiform) atrial tachycardia (MAT) is an abnormal heart rhythm, [2] specifically a type of supraventricular tachycardia, that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease (COPD). Normally, the heart rate is controlled by a cluster of cells called the ...
Sinus node dysfunction ( SND ), also known as sick sinus syndrome ( SSS ), is a group of abnormal heart rhythms ( arrhythmias) usually caused by a malfunction of the sinus node, the heart's primary pacemaker. [1] [2] Tachycardia-bradycardia syndrome is a variant of sick sinus syndrome in which the arrhythmia alternates between fast and slow ...
