One-to-one conduction may occur in patients with accessory AV nodal pathways. In this situation, serious adverse effects are often seen, including palpitations, dizziness, syncope, angina, and dyspnea. Electrical cardioversion is the safest and most reliable way of terminating atria) flutter and ...

21-5). Postoperative atrial flutter typically has 2:1 conduction. If antiarrhythmic drugs have been given as part of routine prophylaxis, the ventricular rate with 2:1 block may be less (125 to 150 beats per minute). Atrial flutter with 2:1 AV block can be difficult to distinguish from ...
Prolonged atrial conduction. A major predisposing factor for the development of atrial flutter. Electrophysiological studies were performed during sinus rhythm on 21 patients who had demonstrated the spontaneous occurrence of sustained atrial flutter...

Atrial flutter is a cardiac arrhythmia characterized by atrial rates of 240-400 beats/min, usually with some degree of atrioventricular (AV) node conduction block (eg, 2:1 or 3:1 block). Approximately 60% of patients with atrial flutter have coronary artery disease (CAD) or hypertensive ...

We focused on one type of AF: AF associated with typical atrial flutter (AFI), which was right atrial (RA) arrhythmia, and sought to investigate intra-atrial electrograms and activation sequences in the transition between AF and AFL.关键词: atrial fibrillation atrial flutter atrial septum ...

36 Occasionally, other arrhythmias such as frequent irregular premature atrial beats and atrial tachycardia (AT)/flutter with variable ventricular response can falsely give the impression of AF. A more careful examination of the EKG, focusing on atrial activity, can be helpful in such cases. The ...
