    Correct Answer
    A. Second degree Heart Block Type I (Mobitz I)
    Explanation
    The correct answer is Second degree Heart Block Type I (Mobitz I). This type of heart block is characterized by a progressive prolongation of the PR interval until a beat is dropped. It is also known as Wenckebach phenomenon. In this EKG rhythm, we can see a progressive lengthening of the PR interval until a QRS complex is dropped, followed by a reset of the cycle. This pattern repeats throughout the rhythm strip, confirming the diagnosis of Mobitz I.

    Identify the following EKG rhythm:

    • A.

      Normal Sinus Rhythm

    • B.

      Junctional Rhythm

    • C.

      Accelerated Junctional Rhythm

    • D.

      Normal Sinus Rhythm with Arrhythmia

    Correct Answer
    C. Accelerated Junctional Rhythm
    Explanation
    The EKG rhythm shown is characterized by a regular rhythm with inverted P waves occurring after each QRS complex, indicating that the atria are not depolarizing before the ventricles. This is consistent with an accelerated junctional rhythm, where the electrical impulse originates from the AV junction instead of the SA node. The absence of any other abnormalities or arrhythmias on the EKG suggests that it is not a normal sinus rhythm with arrhythmia.

    • B.

      Sinus Bradycardia

    • C.

      Atrial Fibrillation

    • D.

      Atrial Flutter

    Correct Answer
    C. Atrial Fibrillation
    Explanation
    The correct answer is Atrial Fibrillation. Atrial fibrillation is a common cardiac arrhythmia characterized by an irregular and often rapid heart rate. In atrial fibrillation, the atria of the heart quiver instead of contracting effectively, leading to an irregular ventricular response. This can result in symptoms such as palpitations, shortness of breath, and fatigue. Atrial fibrillation can increase the risk of stroke and other complications, so it is important to diagnose and manage this condition appropriately.

    • A.

      Normal Sinus Rhythm

    • B.

      Atrial FIbrillation

    • C.

      Ventricular Tachycardia

    • D.

      Atrial Flutter

    Correct Answer
    D. Atrial Flutter
    Explanation
    Atrial flutter is a type of abnormal heart rhythm characterized by rapid and regular atrial contractions. In atrial flutter, the atria beat at a rate of 250-350 beats per minute, causing a fast and regular ventricular response. This can lead to symptoms such as palpitations, shortness of breath, and dizziness. On an EKG, atrial flutter appears as a sawtooth pattern, with a consistent P wave morphology and a regular ventricular response. It is important to distinguish atrial flutter from atrial fibrillation, as the treatment approaches differ.

      Atrial Fibrillation

    • C.

      Normal Sinus Rhythm with PAC

    • D.

      Normal Sinus Rhythm with Arrhythmia

    Correct Answer
    C. Normal Sinus Rhythm with PAC
    Explanation
    The correct answer is "Normal Sinus Rhythm with PAC." This is indicated by the presence of premature atrial contractions (PAC) in an otherwise normal sinus rhythm. PACs are early, abnormal electrical impulses originating from the atria that cause the heart to beat prematurely. These PACs can be seen as an early P wave on the EKG strip, followed by a normal QRS complex. The overall rhythm is still considered normal sinus rhythm because the majority of the beats are originating from the sinus node.

    • C.

      Normal Sinus Rhythm

    • D.

      Slow Atrial Flutter

    Correct Answer
    B. Sinus Bradycardia
    Explanation
    Sinus Bradycardia is the correct answer because the EKG rhythm shows a regular sinus rhythm with a slow heart rate. Sinus Bradycardia is characterized by a heart rate less than 60 beats per minute, which is evident in this EKG. The P waves are present and upright, indicating that they originate from the sinus node. Additionally, the QRS complexes are narrow, suggesting that the electrical conduction through the ventricles is normal. Therefore, based on the EKG findings, Sinus Bradycardia is the most appropriate identification for this rhythm.

      Footprint of Wenckebach

    Correct Answer
    D. Footprint of Wenckebach
    Explanation
    The given EKG rhythm is characteristic of the Footprint of Wenckebach. This rhythm is characterized by a progressive lengthening of the PR interval until a beat is dropped (a P wave is not followed by a QRS complex). This pattern repeats itself in a regular, cyclical manner. Sinus arrhythmia is characterized by irregularity in the timing of the P waves and QRS complexes, Normal Sinus Rhythm is characterized by a regular rhythm with a normal PR interval, and First Degree Heart Block is characterized by a prolonged PR interval without any dropped beats.

    • C.

      Sinus Bradycardia

    • D.

      First Degree Heart Block

    Correct Answer
    D. First Degree Heart Block
    Explanation
    First Degree Heart Block is the correct answer because in this rhythm, there is a prolonged PR interval, which indicates delayed conduction between the atria and ventricles. This delay does not result in dropped beats or missed QRS complexes, distinguishing it from higher-degree heart blocks. In Second Degree Heart Block Type I, there would be a progressive lengthening of the PR interval until a beat is dropped, which is not seen in this EKG rhythm. Normal Sinus Rhythm and Sinus Bradycardia would not show a prolonged PR interval.

      Accelerated Junctional Rhythm

    Correct Answer
    C. Sinus Tachycardia
    Explanation
    The correct answer is Sinus Tachycardia. Sinus tachycardia is a normal rhythm characterized by a fast heart rate originating from the sinus node. In this rhythm, the P wave is present and upright in leads I, II, aVF, and V4-V6. The heart rate is typically greater than 100 beats per minute, but the rhythm is regular. This rhythm is often seen in response to physiological or psychological stress, exercise, fever, pain, or medications.

      Idioventricular Rhythm

    • D.

      Slow PVCs

    Correct Answer
    C. Idioventricular Rhythm
    Explanation
    An idioventricular rhythm is characterized by a slow heart rate, typically less than 40 beats per minute, with wide QRS complexes and no discernible P waves. This rhythm occurs when the ventricles of the heart take over as the primary pacemaker, usually due to a failure of the normal pacemaker cells in the atria or the atrioventricular node. Asystole refers to a complete absence of electrical activity in the heart, so it is not the correct answer. Sinus bradycardia refers to a slow heart rate with normal sinus rhythm, which is not seen in this EKG. Slow PVCs is not a recognized rhythm.

    • D.

      Atrial Fibrillation with Bundle Branch changes

    Correct Answer
    C. Normal Sinus Rhythm with Couplet PVCs and Single PAC
    Explanation
    The EKG rhythm is identified as "Normal Sinus Rhythm with Couplet PVCs and Single PAC". This means that the EKG shows a normal sinus rhythm, which is the normal electrical activity of the heart. In addition, there are two premature ventricular contractions (PVCs) occurring in a row (couplet) and one premature atrial contraction (PAC). PVCs and PACs are extra heartbeats that can occur due to various reasons, but in this case, they are occurring within the context of a normal sinus rhythm.

      Artifact

    Correct Answer
    B. Ventricular Fibrillation
    Explanation
    The correct answer is Ventricular Fibrillation. Ventricular fibrillation is a life-threatening cardiac rhythm disturbance characterized by chaotic and disorganized electrical activity in the ventricles. It is typically associated with loss of consciousness, absence of a palpable pulse, and absence of effective cardiac output. Immediate medical intervention, such as defibrillation, is required to restore a normal heart rhythm and prevent cardiac arrest.
