<bold>FIGURE 27-10</bold> Electrocardiographic tracings of atrial arrhythmias. Atrial flutter (<italic>first tracing</bold>) is characterized by the atrial flutter (F) waves occurring at a rate of 240 to 450 beats per minute. The ventricular rate remains regular because of the conduction of every sixth atrial contraction. Atrial fibrillation (<italic>second tracing</bold>) has grossly disorganized atrial electrical activity that is irregular with respect to rate and rhythm. The ventricular response is irregular,...

Atrial flutter presenting as wide-QRS tachycardia. A: A 12-lead electrocardiogram (ECG) from a patient presenting to the emergency room with palpitations. This patient had clinical atrial fibrillation treated with a type Ic antiarrhythmic medication. The patient also had relatively robust atrioventricular nodal conduction. The wide-QRS tachycardia had a rate of approximately 180 beats per minute. B: Transient slowing of atrioventricular conduction resulting in narrowing of the QRS and ident...

Atrial fibrillation with a rapid ventricular response rate during Wolff-Parkinson-White syndrome. Initial atrioventricular reentrant tachycardia degenerates into atrial fibrillation (arrow). The shortest RR interval in this case was 240 to 250 msec, which indicates an increased risk for sudden cardiac death.
