Read the first 6 Atrial Arrhythmia Identification flashcards as text

  1. Which atrial arrhythmia is characterized by a sawtooth pattern at a rate of 250-350 bpm on the ECG?

    Answer: Atrial flutter

    Atrial flutter produces the classic sawtooth flutter waves (F waves) at 250-350 bpm, best visible in leads II, III, aVF, and V1.

  2. In atrial fibrillation, which ECG finding is most characteristic?

    Answer: Irregularly irregular rhythm with absent distinct P waves

    Atrial fibrillation produces an irregularly irregular ventricular rhythm and replaces distinct P waves with chaotic fibrillatory f waves at 350-600 bpm.

  3. A rhythm strip shows P wave morphology varying in at least three different shapes with an irregular rate above 100 bpm. What arrhythmia is present?

    Answer: Multifocal atrial tachycardia

    Multifocal atrial tachycardia (MAT) is defined by three or more distinct P wave morphologies, an irregular rhythm, and a rate greater than 100 bpm.

  4. Paroxysmal supraventricular tachycardia (PSVT) most commonly has which ventricular rate range?

    Answer: 150-250 bpm

    PSVT characteristically presents with a sudden-onset, regular tachycardia at 150-250 bpm with narrow QRS complexes unless aberrant conduction is present.

  5. A P wave with negative deflection in lead I and positive deflection in aVR most likely indicates which condition?

    Answer: Ectopic atrial rhythm originating from the left atrium

    A negative P wave in lead I and positive in aVR suggests retrograde or left-sided atrial activation, characteristic of a left atrial ectopic focus.

  6. Atrial flutter with 4:1 AV conduction produces a ventricular rate of approximately how many bpm if the atrial rate is 300 bpm?

    Answer: 75 bpm

    With an atrial flutter rate of 300 bpm and 4:1 conduction, 300 divided by 4 equals 75 bpm.
