  • 2. 
    This Rhythm strip is: - ProProfs

    This Rhythm strip is:

    • V tach

    • Normal sinus rhythm

    • Atrial fibrillation

    • Asystole

    Correct Answer
    A. Atrial fibrillation
    Explanation
    Atrial fibrillation is a type of arrhythmia characterized by an irregular and rapid heartbeat. In this rhythm strip, there is no discernible P wave, and the QRS complexes are irregularly spaced. This suggests that the atria are not contracting in a coordinated manner, leading to the irregular rhythm. Therefore, the correct answer is atrial fibrillation.

    Rate this question:

  • 3. 
    This Rhythm strip is: - ProProfs

    This Rhythm strip is:

    • Sinus tachycardia

    • Junctional rhythm

    • Sinus bradycardia

    • Normal sinus rhythm

    Correct Answer
    A. Sinus bradycardia
    Explanation
    The given rhythm strip is identified as sinus bradycardia because the P waves are present and upright in leads II, III, and aVF, indicating a sinus origin. The heart rate is below the normal range, with a slow and regular rhythm. The QRS complexes are narrow, suggesting that the electrical conduction through the ventricles is normal. Therefore, based on these characteristics, the rhythm strip is consistent with sinus bradycardia.

    This Rhythm strip is:

    • Atrial fibrillation

    • Atrial flutter

    • Ventricular fibrillation

    • Ventricular tachycardia

    Correct Answer
    A. Atrial flutter
    Explanation
    Based on the given information, the correct answer is atrial flutter. Atrial flutter is a type of abnormal heart rhythm characterized by rapid and regular atrial contractions. It is different from atrial fibrillation, which is characterized by rapid and irregular atrial contractions. Ventricular fibrillation and ventricular tachycardia are both abnormal rhythms that originate in the ventricles of the heart, whereas atrial flutter originates in the atria.

    This Rhythm strip is:

    • Ventricular fibrillation

    • A fib

    • Normal sinus rhythm

    • V tach

    Correct Answer
    A. A fib
    Explanation
    The correct answer is "a fib" which stands for atrial fibrillation. Atrial fibrillation is a type of irregular heart rhythm where the atria (upper chambers of the heart) quiver instead of contracting normally. This can lead to an irregular and often rapid ventricular (lower chamber) heart rate. It is characterized by the absence of distinct P waves and irregularly irregular QRS complexes on an ECG strip.

    This Rhythm strip is:

    • Normal sinus rhythm

    • Atrial fibrillation

    • Asystole

    • V tach

    Correct Answer
    A. Normal sinus rhythm
    Explanation
    The given answer "normal sinus rhythm" suggests that the rhythm strip being referred to in the question shows a normal electrical activity of the heart. In a normal sinus rhythm, the heart's electrical signals originate from the sinus node, leading to regular and coordinated contractions of the atria and ventricles. This rhythm is characterized by a consistent P wave preceding each QRS complex, with a regular rate and normal intervals between each wave.

    This Rhythm strip is:

    • V tach

    • Junctional tachycardia

    • Atrial fibrillation

    • Asystole

    Correct Answer
    A. Junctional tachycardia
    Explanation
    Based on the given options, the rhythm strip can be identified as junctional tachycardia. This is because junctional tachycardia is characterized by a regular rhythm with a heart rate of more than 100 beats per minute, and the absence of P waves. In the given strip, there are no visible P waves and the QRS complexes are narrow and regular, indicating a junctional origin of the tachycardia. Therefore, the correct answer is junctional tachycardia.

    This Rhythm strip is:

    • V tach

    • V fib

    • Atrial fibrillation

    • Asystole

    Correct Answer
    A. V fib
    Explanation
    The correct answer is v fib, which stands for ventricular fibrillation. Ventricular fibrillation is a life-threatening cardiac arrhythmia characterized by chaotic and disorganized electrical activity in the ventricles. This results in the ineffective pumping of blood, leading to cardiac arrest. Immediate medical intervention, such as defibrillation, is required to restore a normal heart rhythm and prevent further complications.

    This Rhythm strip is:

    • Aystole

    • Agonal rhythm

    • Sinus bradychardia

    • V tach

    Correct Answer
    A. Agonal rhythm
    Explanation
    An agonal rhythm refers to a chaotic, irregular, and disorganized electrical activity of the heart. It is often seen in patients who are in a critical condition and experiencing cardiac arrest or near-death. This rhythm strip is indicative of agonal rhythm due to its irregularity and lack of any discernible pattern. The absence of clear P waves, QRS complexes, and T waves further supports this interpretation.

    This Rhythm strip is:

    • Normal sinus rhythm

    • Sinus bradycardia

    • Sinus arrythmia

    • 1st degree av block

    Correct Answer
    A. Sinus bradycardia
    Explanation
    The given rhythm strip is identified as sinus bradycardia because the rhythm is regular and originates from the sinus node, as indicated by the presence of P waves before each QRS complex. However, the heart rate is slower than normal, with a heart rate less than 60 beats per minute. This can be seen by measuring the distance between two consecutive R waves and calculating the heart rate.

    This Rhythm strip is:

    • Normal sinus rhythm with pjc's

    • Normal sinus rhythm

    • Atrial fibrillation

    • V tach

    Correct Answer
    A. Normal sinus rhythm with pjc's
    Explanation
    The given rhythm strip is classified as "normal sinus rhythm with pjc's." This means that the electrical activity of the heart is normal, with a regular rhythm originating from the sinus node. However, there are also premature junctional contractions (PJC's) present, which are early contractions originating from the atrioventricular (AV) junction instead of the sinus node. These PJC's can be seen as abnormal beats interrupting the regular sinus rhythm. Overall, the rhythm strip shows a normal sinus rhythm with the addition of premature junctional contractions.

    This Rhythm strip is:

    • Ventricular fibrillation

    • V tach

    • SVT

    • A fib

    Correct Answer
    A. Ventricular fibrillation
    Explanation
    The correct answer is ventricular fibrillation. Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic and disorganized electrical activity in the ventricles. This results in ineffective pumping of blood and can lead to cardiac arrest. It is typically seen as a rapid and irregular rhythm with no discernible P waves or QRS complexes on an ECG. Prompt intervention with defibrillation is necessary to restore a normal heart rhythm and prevent cardiac arrest.

    This Rhythm strip is:

    • 3rd degree block

    • 2nd degree type 2 block

    • Accelerated indioventricular rhythm

    • Normal sinus rhythm

    Correct Answer
    A. 2nd degree type 2 block
    Explanation
    The given rhythm strip is most likely a 2nd degree type 2 block. This can be inferred from the presence of dropped QRS complexes, which indicates intermittent conduction block at the level of the AV node or bundle of His. In a 2nd degree type 2 block, there is a fixed ratio of conducted to blocked P waves, resulting in a regular pattern of dropped beats. This is different from a 3rd degree block, where there is complete dissociation between the atria and ventricles, and from an accelerated idioventricular rhythm, which typically has a slower rate and wide QRS complexes. Normal sinus rhythm would not exhibit dropped beats.

    • Atrial fibrillation

    • Asystole

    Correct Answer
    A. Atrial fibrillation
    Explanation
    The given rhythm strip is likely to be atrial fibrillation because it lacks a discernible P wave and shows irregular and chaotic QRS complexes. Atrial fibrillation is characterized by the absence of coordinated atrial contractions, resulting in an irregular ventricular response. This is evident in the strip as the QRS complexes occur at irregular intervals.

    This Rhythm strip is:

    • Normal sinus rhythm

    • Junctional rhythm

    • Sinus tachycardia

    • Idioventricular rhythm

    Correct Answer
    A. Junctional rhythm
    Explanation
    This ECG rhythm strip displays a rapid, regular rhythm with narrow QRS complexes, but crucially, it lacks discernible P waves. The absence of P waves eliminates sinus tachycardia. The consistent R-R intervals and narrow QRS complexes point to a supraventricular origin. Given the lack of P waves, the most likely source is the AV node, indicating junctional tachycardia. In this rhythm, the AV node paces the heart, leading to a rapid, regular rate without preceding atrial depolarization. Therefore, junctional tachycardia is the correct interpretation, distinguishing it from sinus tachycardia and other rhythms.

    This Rhythm strip is:

    • Second degree type 2

    • Third degree

    • Atrial fibrillation

    • First degree av block

    Correct Answer
    A. Atrial fibrillation
    Explanation
    The correct answer is atrial fibrillation. Atrial fibrillation is a type of irregular heart rhythm where the atria (upper chambers of the heart) quiver instead of contracting effectively. This can lead to an irregular and fast ventricular response. In this rhythm strip, there is no discernible P waves and the R-R intervals are irregular, indicating atrial fibrillation.

    This Rhythm strip is:

    • 3rd degree av block

    • Accelerated idioventricular rhythm

    • 2nd degree type 2 av block

    • V tach

    Correct Answer
    A. 2nd degree type 2 av block
    Explanation
    The ECG strip shows a regular R-R interval, but the P waves and QRS complexes have no clear relationship.  While the initial answer was 3rd-degree AV block, a closer look reveals consistent PR intervals for conducted beats with occasional dropped QRS complexes. This pattern suggests 2nd-degree AV block type 2 (Mobitz II). In this type, the PR interval remains constant for conducted beats, unlike 3rd-degree AV block where there's no relationship between P waves and QRS complexes. Therefore, the more accurate interpretation is 2nd-degree AV block type 2.

    This Rhythm strip is:

    • Normal sinus rythm

    • Junctional tachycardia

    • Sinus tachycardia

    • Atrial fibrillation

    Correct Answer
    A. Atrial fibrillation
    Explanation
    The ECG presents an irregularly irregular rhythm with a rapid rate. Distinct P waves are absent, replaced by a chaotic baseline, indicating fibrillatory activity. The QRS complexes are narrow, suggesting a supraventricular origin. These features are consistent with atrial fibrillation. The irregular R-R intervals and lack of defined P waves differentiate atrial fibrillation from other tachycardias, such as sinus tachycardia or SVT, which typically exhibit regular rhythms. Therefore, atrial fibrillation is the most accurate interpretation of this rhythm strip.

    Correct Answer
    A. Sinus tachycardia
    Explanation
    The ECG rhythm strip exhibits a regular rhythm with clear P waves preceding each narrow QRS complex. While these features align with normal sinus rhythm, the crucial factor is the heart rate. If the rate is confirmed to be above 100 bpm, the correct interpretation is sinus tachycardia. Sinus tachycardia is characterized by a rapid heart rate originating from the sinoatrial node. The presence of P waves and narrow QRS complexes confirms the sinus origin. Therefore, if the rate exceeds 100 bpm, sinus tachycardia is the accurate diagnosis, distinguishing it from normal sinus rhythm.
