Dysrhythmias

Mia is studying an ECG diagram in her medical class. She observes that Sinus Dysrhythmia is characterized by:

• Irregular heart rhythm that varies with breathing

• Consistent heart rhythm regardless of breathing

• Complete absence of P waves

• Inverted T waves

During a medical class, Avery was asked to identify a characteristic of Sinus Arrest on an ECG diagram. What did Avery observe?

• a complete absence of P waves

• a prolonged PR interval

• a regular rhythm

• a short QT interval

What is the primary location where Junctional Dysrhythmias occur?

James is studying an ECG diagram in his medical class. He needs to describe the characteristics of a Premature Junctional Complex (PJC) based on the diagram.

• A PJC is characterized by a premature, narrow QRS complex with no preceding P wave or an inverted P wave.

• A PJC is characterized by a wide QRS complex with a preceding P wave.

• A PJC is characterized by a regular rhythm with a prolonged PR interval.

• A PJC is characterized by an irregular rhythm with a normal PR interval.

What is the primary location where Junctional Dysrhythmias occur?

Michael, a medical student, is analyzing an ECG diagram during his cardiology class. Describe the characteristics of Junctional Tachycardia Rhythm/Supraventricular Tachycardia (SVT) that he observes.

• Junctional Tachycardia is characterized by a regular rhythm with a rate of 100-180 bpm, narrow QRS complexes, and absent or inverted P waves.

• Junctional Tachycardia is characterized by an irregular rhythm with a rate of 60-100 bpm, wide QRS complexes, and visible P waves.

• Junctional Tachycardia is characterized by a regular rhythm with a rate of 40-60 bpm, narrow QRS complexes, and visible P waves.

• Junctional Tachycardia is characterized by an irregular rhythm with a rate of 100-180 bpm, narrow QRS complexes, and absent or inverted P waves.

During a medical class, Maya learned that Ventricular Dysrhythmias are considered more dangerous and life-threatening because:

• They occur in the atria of the heart.

• They are associated with the ventricles of the heart.

• They are always benign and not serious.

• They have no impact on heart function.

William, a medical student, is reviewing an ECG diagram during his cardiology class. Identify the type of ventricular dysrhythmia shown in the first ECG diagram.

• A) Premature Ventricular Complexes (PVCs)

• B) Ventricular Tachycardia

• C) Ventricular Fibrillation

During a medical training session, Ethan is shown an ECG diagram. Identify the type of ventricular dysrhythmia shown in the second ECG diagram.

• A) Premature Ventricular Complexes (PVCs)

• B) Ventricular Tachycardia

• C) Ventricular Fibrillation

During a medical training session, Rohan is shown diagrams labeled 'Idioventricular rhythm/Agonal Rhythm'. What type of rhythm is this?

• Normal Sinus Rhythm

• Idioventricular Rhythm

• Atrial Fibrillation

• Ventricular Tachycardia
