Identify the following rhythm (lead II): ____________________

Delivery of an electrical current timed for delivery during the QRS complex is called _____ _____.

Identify the following rhythm (lead II): ____________________

The presence of an accessory pathway should be considered in atrial fibrillation with a ventricular rate faster than 180 beats/min.

Identify the following rhythm: ____________________

A 77-year-old woman is complaining of a sudden onset of palpitations.The cardiac monitor reveals atrial fibrillation with a ventricular response of 144 to 210 beats/min while the patient is at rest.In this situation,the ventricular rate associated with this rhythm is considered to be _____.

Identify the following rhythm (lead II).

Identify the following rhythm (lead II): ____________________

Identify the following rhythm (lead III): ____________________

Complete the following ECG criteria for Wolff-Parkinson-White (WPW)syndrome: Rlythm_______________________________________________ Rate__________________________________________________ p waves____________________________________________________ PR interval_________________________________________________ QRS duration________________________________________________

In atrial fibrillation,the AV node attempts to protect the ventricles from the hundreds of impulses bombarding it per minute by blocking many of the impulses generated by the irritable sites in the atria.

Identify the following rhythm (lead II): ____________________

To determine whether the ventricular rhythm on an ECG tracing is regular or irregular,compare _____ intervals.

Identify the following rhythm (lead II): ____________________

Identify the following rhythm (lead II): ____________________

Identify the following rhythm (lead II).

Complete the following ECG criteria for atrial tachycardia: Rlythm______________________________________ Rate____________________________________________ p waves_____________________________________________ PR interval_________________________________________ QRS duration____________________________________________

Upon conversion of atrial fibrillation to sinus rhythm,the patient should be observed for signs of a possible stroke.
