    • A.

      Ventricular Tachycardia

    • B.

      Sinus Tachycardia

    • C.

      Sinus Bradycardia

    • D.

      Normal Sinus Rhythm

    Correct Answer
    D. Normal Sinus Rhythm
    Explanation
    The correct answer is "Normal Sinus Rhythm". Normal Sinus Rhythm refers to the normal electrical activity of the heart, where the heart rate is within the normal range (60-100 beats per minute) and the rhythm originates from the sinus node. This rhythm indicates that the heart is functioning properly and is not experiencing any abnormal or irregular heartbeats.

    Name this strip.

    • A.

      Ventricular Fibrillation

    • B.

      Slow Atrial Fibrillation

    • C.

      Normal Sinus Rhythm

    • D.

      Sinus Bradycardia

    Correct Answer
    D. Sinus Bradycardia
    Explanation
    Sinus Bradycardia is the correct answer because it refers to a normal heart rhythm with a slow heart rate. In this condition, the heart's electrical signals originate from the sinus node, but the heart rate is slower than the normal range. It is characterized by a regular rhythm and a heart rate of less than 60 beats per minute. Ventricular Fibrillation and Slow Atrial Fibrillation are incorrect choices as they represent abnormal heart rhythms, while Normal Sinus Rhythm refers to a normal heart rhythm with a normal heart rate.

    • A.

      Supraventricular Tachycardia

    • B.

      Sinus Tachycardia

    • C.

      Atrial Tachycardia

    • D.

      Atrial Flutter

    Correct Answer
    B. Sinus Tachycardia
    Explanation
    Sinus tachycardia is the correct answer because it is a type of tachycardia that originates from the sinoatrial (SA) node, which is the natural pacemaker of the heart. In sinus tachycardia, the heart rate is increased above the normal range (typically greater than 100 beats per minute) due to an increased firing rate of the SA node. This can be caused by various factors such as exercise, stress, fever, or certain medications. Supraventricular tachycardia, atrial tachycardia, and atrial flutter are all different types of tachycardia but they do not specifically involve the SA node.

      Normal Sinus Rhythm with PVC'S

    • B.

      Normal Sinus Rhythm with PAC'S

    • C.

      Normal Sinus Rhythm with PJC'S

    • D.

      Normal Sinus Rhythm

    Correct Answer
    B. Normal Sinus Rhythm with PAC'S
    Explanation
    The correct answer is "Normal Sinus Rhythm with PAC'S". This is because PAC's (Premature Atrial Contractions) are abnormal electrical impulses that originate in the atria and disrupt the normal sinus rhythm. In this case, the ECG strip shows a normal sinus rhythm with occasional premature atrial contractions.

    • C.

      Normal Sinus Rhythm with PAC'S

    • D.

      Normal Sinus Rhythm with PJC'S

    Correct Answer
    A. Normal Sinus Rhythm with Multifocal PVC'S
    Explanation
    This strip can be named "Normal Sinus Rhythm with Multifocal PVC's" because it shows a normal sinus rhythm, meaning the electrical activity in the heart is normal. However, it also shows premature ventricular contractions (PVC's) that are multifocal, meaning they originate from different sites in the ventricles.

    • C.

      Normal Sinus with PVC'S

    • D.

      Normal Sinus Rhythm

    Correct Answer
    A. Normal Sinus Rhythm with PJC'S
    Explanation
    The correct answer is "Normal Sinus Rhythm with PJC'S". This is because the strip shows a normal sinus rhythm, which is characterized by a regular pattern of P waves, QRS complexes, and T waves. Additionally, there are premature junctional complexes (PJC's) present, which are indicated by the abnormal P waves occurring earlier than expected. Therefore, the correct name for this strip is "Normal Sinus Rhythm with PJC'S".

    • D.

      Sinus Bradycardia with PVC'S

    Correct Answer
    A. Normal Sinus Rhythm with Unifocal Couplet PVC'S
    Explanation
    The correct answer is "Normal Sinus Rhythm with Unifocal Couplet PVC'S". This is because the term "Normal Sinus Rhythm" refers to the normal electrical activity of the heart, while "Unifocal Couplet PVC'S" indicates the presence of two premature ventricular contractions (PVC's) that originate from the same location in the ventricles.

    • C.

      Normal Sinus Rhythm with PJC's

    • D.

      Normal Sinus with PAC'S

    Correct Answer
    A. Normal Sinus Rhythm with Unifocal PVC'S
    Explanation
    The correct answer is "Normal Sinus Rhythm with Unifocal PVC'S." This is because the strip shows a normal sinus rhythm, which is indicated by the regular P waves, consistent PR intervals, and QRS complexes. Additionally, there are premature ventricular contractions (PVC's) present, which are indicated by the wide and bizarre QRS complexes that occur earlier than expected. The term "unifocal" refers to the fact that all the PVC's have the same morphology, meaning they look the same.

      2ND Degree Type II

    • D.

      3RD Degree Block

    Correct Answer
    B. 2ND Degree Type 1/ Wenchebach
    Explanation
    The correct answer is 2ND Degree Type 1/ Wenchebach. This refers to a heart rhythm disorder where there is a progressive lengthening of the PR interval until a beat is dropped. This pattern repeats itself, and it is known as Wenchebach or Mobitz Type 1 block. In this condition, the electrical signals between the atria and ventricles are delayed or blocked, leading to an irregular heartbeat.

    • D.

      Slow V-Tach

    Correct Answer
    C. 3RD Degree Block
    Explanation
    The given options are different medical conditions related to the heart's electrical conduction system. "3RD Degree Block" refers to a complete blockage of the electrical signals between the atria and ventricles, causing them to beat independently. This condition disrupts the normal rhythm and coordination of the heart, which can lead to symptoms like dizziness, fainting, and fatigue.

      Atrial Fibrillation

    • D.

      Atrial Flutter

    Correct Answer
    C. Atrial Fibrillation
    Explanation
    The correct answer is Atrial Fibrillation. Atrial Fibrillation is a type of cardiac arrhythmia characterized by irregular and rapid electrical impulses in the atria of the heart. In this strip, there are no discernible P waves, indicating the absence of organized atrial activity. Instead, there are irregular, chaotic, and rapid fibrillatory waves present. This pattern is consistent with Atrial Fibrillation.

      Atrial Fibrillation

    • D.

      Atrial Flutter

    Correct Answer
    D. Atrial Flutter
    Explanation
    The correct answer is Atrial Flutter. Atrial flutter is a type of abnormal heart rhythm characterized by rapid and regular atrial contractions. In this ECG strip, the rhythm is regular and the atrial waves (P waves) are not clearly visible. Instead, there are sawtooth-shaped waves that represent atrial flutter waves. This is a characteristic finding in atrial flutter. The presence of ST elevation or artifact would not be consistent with atrial flutter.

    • C.

      Accelerated Junctional Rhythm

    • D.

      Normal Sinus Rhythm

    Correct Answer
    C. Accelerated Junctional Rhythm
    Explanation
    The correct answer is "Accelerated Junctional Rhythm." This is because the strip shows a regular rhythm with narrow QRS complexes and no discernible P waves. The absence of P waves indicates that the atria are not initiating the electrical impulse, and the presence of a regular rhythm suggests that the impulse is originating from the AV junction. Additionally, the term "accelerated" indicates that the rhythm is faster than the normal junctional rhythm.

    • C.

      Normal Sinus Rhythm

    • D.

      Junctional Rhythm

    Correct Answer
    A. Normal Sinus with 1st Degree AV Block
    Explanation
    This strip is named "Normal Sinus with 1st Degree AV Block" because it shows a normal sinus rhythm with a prolonged PR interval, which indicates a first-degree atrioventricular (AV) block. A first-degree AV block is characterized by a delay in the conduction of electrical impulses from the atria to the ventricles, resulting in a longer PR interval on the ECG.

    • A.

      Sinus Rhythm with a very short P-R

    • B.

      Sinus Brady with a very short P-R

    • C.

      Normal Sinus Rhythm

    • D.

      Junctional Rhythm

    Correct Answer
    D. Junctional Rhythm
    Explanation
    The given strip is most likely a Junctional Rhythm because it shows a very short P-R interval. In a Junctional Rhythm, the electrical impulse originates from the AV node or the junction between the atria and ventricles, resulting in a P-wave that is either absent or inverted. The P-R interval represents the time it takes for the electrical impulse to travel from the atria to the ventricles, and in a Junctional Rhythm, this interval is usually shorter than normal. Therefore, the correct answer is Junctional Rhythm.

    • D.

      2ND Degree Type I

    Correct Answer
    A. Normal Sinus Rhythm with Bundle Branch Block
    Explanation
    The correct answer is Normal Sinus Rhythm with Bundle Branch Block. This is because the strip shows a regular rhythm with normal P waves and QRS complexes, indicating normal sinus rhythm. However, there is a delay or blockage in one of the bundle branches, causing a widened QRS complex. This is characteristic of a bundle branch block.

    • C.

      Atrial Flutter with a fast rate

    • D.

      Sinus Tachycardia

    Correct Answer
    B. Atrial Tachycardia
    Explanation
    Atrial tachycardia is the correct answer because it refers to a condition where the heart's electrical signals originate from abnormal sites within the atria, causing a rapid heart rate. This is different from sinus tachycardia, which occurs when the heart rate increases due to normal physiological responses. Atrial fibrillation with a fast rate and atrial flutter with a fast rate both involve abnormal heart rhythms, but they are not specifically characterized by a rapid heart rate originating from abnormal atrial sites like atrial tachycardia.

    • C.

      VVI Pacemaker with No Capture

    • D.

      Slow Ventricular Tachycardia

    Correct Answer
    B. VVI Pacemaker with 100% Capture
    Explanation
    The strip shown is indicative of a VVI pacemaker with 100% capture. In this type of pacemaker rhythm, the pacemaker is set to stimulate the ventricles (V) when the intrinsic rhythm is too slow or absent. The presence of regular ventricular pacing spikes followed by QRS complexes indicates that the pacemaker is successfully capturing the ventricles and causing them to depolarize. The absence of any other electrical activity suggests that there is no intrinsic conduction occurring.
