An abnormally fast heart rate is calledtachycardia. Because atrial flutter comes from the atria, it is called a supraventricular (meaning above the ventricles) tachycardia. Types of Atrial Flutter There are two main types of atrial flutter: ...
We studied the modes of initiation of two types of atria] reentrant tachycardias (i.e., microreentry isthmus tachycardia and counterclockwise atrial flutter) in a 39-year-old male with typical atrial flutter. Rapid atrial pacing from proximal coronary sinus at a cycle length of 220 msec ...
Atrial flutter 心房扑动 心房扑动。心房扑动与房颤相似,但心房扑动时的心跳比心房颤动时产生的电脉冲更有组织性,也更有节奏。心房扑动也可能导致严重的并发症,如中风。 · Supraventricular tachycardia. Supraventricular tachycardia is a broad term that includes many forms of arrhythmia originating above th...
Atrial fibrillationoccurs when the atrium has lost the ability to beat in a coordinated fashion. Instead of the SA node generating a single electrical signal, numerous areas of the atrium become irritated and produce electrical impulses. This causes the atrium to jiggle, or fibrillate, instead of...
Atrial fibrillation:This is a common condition caused by electrical impulses discharged at a rapid rate from many different areas of the atria. It usually causes a fast and irregular heartbeat. Atrial flutter:This condition is caused by a rapid discharge from a single place in the right atrium...
The electrophysiologic determinants of conversion and the prevention of atrial flutter are poorly defined. This issue was therefore investigated by evaluating the effects of the new class III antiarrhythmic drug d-sotalol and the class I... GK Feld,N Venkatesh,BN Singh - 《Circulation》 被引量:...
Forms of electrical system disease include heart block, long QT syndrome, tachycardia, atrial flutter, and ventricular fibrillation. The heart valves include the pulmonary, aortic, tricuspid, and mitral valves. The tricuspid and mitral valves are located inside of the heart between ventricles and ...
Abnormal EKG results could be a sign of several conditions, including: Atrial fibrillation/flutter Heart attack(current or past) Heart failure Genetic heart defects Abnormal heart rhythms (arrhythmias) Sick sinus syndrome Wolff-Parkinson-White syndrome ...
The analysis was approved by the regional ethics committee (Landesaerztekammer Hessen) and carried out in accordance with the Declaration of Helsinki. Efficacy and safety endpoints Primary efficacy endpoint was defined as first documented recurrence of clinical AF, atrial flutter, or atrial tachycardia...
Atrial fibrillation Atrial flutter SVT Causes SVT is usually caused by things you can't control, such as a medical condition or previous surgery. Sometimes, an episode is triggered by stress, exercise, or lack of sleep, though it usually happens without any obvious reason. ...
