Mastering Cardiac Arrhythmias: An Interactive Quiz

1. What defines a normal sinus rhythm (NSR)?

A normal sinus rhythm (NSR) is characterized by specific parameters including heart rate, rhythm regularity, P wave presence relative to QRS Complexes, PR interval duration, and QRS Complex duration. Any deviation from these criteria would indicate an abnormality in the heart's electrical conduction system.

A normal sinus rhythm (NSR) is characterized by specific parameters including heart rate, rhythm regularity, P wave presence relative to QRS Complexes, PR interval duration, and QRS Complex duration. Any deviation from these criteria would indicate an abnormality in the heart's electrical conduction system.

2. Which of the following best describes SINUS BRADYCARDIA?

Sinus bradycardia is characterized by a heart rate (HR) less than 60 beats per minute, a regular rhythm with typically 42-59 BPM range, one P wave for each QRS complex, PR interval of 0.12 - 0.20 seconds, and a QRS duration of 0.04 - 0.10 seconds.

Explanation

Sinus bradycardia is characterized by a heart rate (HR) less than 60 beats per minute, a regular rhythm with typically 42-59 BPM range, one P wave for each QRS complex, PR interval of 0.12 - 0.20 seconds, and a QRS duration of 0.04 - 0.10 seconds.

3. What are the characteristics of SINUS TACHYCARDIA?

Sinus tachycardia is characterized by a heart rate ranging from 100 - 180 beats per minute. The rhythm is regular with 1 P wave for each QRS complex. The PR interval falls in the range of 0.12 - 0.20 seconds, while the QRS complex duration is between 0.04 - 0.10 seconds. It's important to differentiate between various cardiac arrhythmias based on these specific criteria.

4. What is the typical presentation of SINUS ARRHYTHMIA on an EKG?

SINUS ARRHYTHMIA is characterized by a heart rate of 60 - 100 BPM with a regular rhythm that varies with respiration. The EKG typically shows 1 P wave for each QRS complex, PR interval between 0.12 - 0.20 sec, and QRS complex duration of 0.04 - 0.10 sec.

Explanation

SINUS ARRHYTHMIA is characterized by a heart rate of 60 - 100 BPM with a regular rhythm that varies with respiration. The EKG typically shows 1 P wave for each QRS complex, PR interval between 0.12 - 0.20 sec, and QRS complex duration of 0.04 - 0.10 sec.

A tool used for taking blood pressure readings.

A tool used for drawing perfect circles.

A tool used for measuring angles in geometry.

A tool used in helping analyze and EKG reading.

Calipers are actually used in the medical field to help analyze an EKG reading by measuring intervals and amplitudes of the electrical waves on the EKG graph.

Explanation

Calipers are actually used in the medical field to help analyze an EKG reading by measuring intervals and amplitudes of the electrical waves on the EKG graph.

8. Where is voltage typically plotted on a graph?

On the vertical axis

Nowhere on the graph.

In the legend of the graph.

On the horizontal axis.

Voltage is a dependent variable and is usually plotted on the vertical axis of a graph to show how it changes in relation to the independent variable plotted on the horizontal axis.

Explanation

Voltage is a dependent variable and is usually plotted on the vertical axis of a graph to show how it changes in relation to the independent variable plotted on the horizontal axis.

9. Which of the following are variations of Normal Sinus Rhythm (NSR)?

Premature Atrial Contraction

Ventricular Tachycardia

Atrial Fibrillation

Sinus BradycardiaSinus TachycardiaSinus Arrythmia

Normal Sinus Rhythm (NSR) includes Sinus Bradycardia, Sinus Tachycardia, and Sinus Arrhythmia as variations. Atrial Fibrillation, Ventricular Tachycardia, and Premature Atrial Contraction are different cardiac arrhythmias that are not classified under Normal Sinus Rhythm.
