EKG Rhythms

Which of the following is a characteristic feature of ventricular fibrillation on an EKG?

• Regular, narrow QRS complexes

• A sawtooth pattern of atrial activity

• Chaotic and irregular QRS complexes with no discernible pattern

• P waves with no accompanying QRS complexes

Reorder the following steps to recognizing EKG telemetry

• Check whether rhythm is regular

• Determine heart rate

• Are there P waves (1 for each QRS)

• Is there a QRS (1 for each P wave) and are they the same

• Name the Rhythm

Match the following EKG descriptions to the correct cardiac arrhythmia

• Asystole

• Irregular QRS, Sawtooth Pattern, PR intervals not measurable

• Atrial fibrillation

• Quivering, No Pulse, No P waves, No QRS

• Atrial Flutter

• Rapid irregular QRS complex with QT Prolongation

• Tosades De Pointes

• No P waves, No QRS, Nothing on EKG

• Ventricular Fibrillation

• Irregular beats, wavy P waves, no regular PR intervals (more P-waves than qrs complexes)

Match the following symptoms with the type of tachycardia: 1) No P waves 2) PR interval not measurable 3) D-fib the Vfib

• No P waves

• Ventricular tachycardia

• D-fib the Vfib

• Supraventricular Tachycardia

• PR interval not measurable

• Both

Which of the following is NOT a symptom of Fine Ventricular Fibrillation?

• No pulse

• No P waves

• Rapid irregular QRS complex

• Quivering

Which arrhythmia is characterized by a irregular rhythm with no discernible P waves?

• Ventricular tachycardia

• Atrial fibrillation

• Atrial flutter

• Sinus bradycardia

Which type of arrhythmia is characterized by a sawtooth pattern on an EKG?

• Ventricular fibrillation

• Atrial flutter

• Atrial fibrillation

• Ventricular tachycardia

Which of the following best describes the EKG feature of "premature ventricular contractions" (PVCs)?

• A P wave followed by a QRS complex that occurs earlier than expected

• A QRS complex that occurs without a preceding P wave and is wide and bizarre in appearance

• A rapid succession of three or more ventricular ectopic beats

• A regular rhythm with an abnormally long PR interval

What is the significance of an inverted T wave on an EKG?

• It is a normal variant in children and some adults.

• It may indicate myocardial ischemia.

• It signifies rapid heart rate.

• It is indicative of atrial fibrillation.
