1. What is the rate? More than 60 beats per minute 2. What is the rhythm? Atrial rhythm irregular Ventricular rhythm regular 3. Is there a P wave before each QRS? Are P waves upright and uniform? Yes No

1. What is the rate? Less than 60 beats per minute 2. What is the rhythm? Atrial rhythm regular Ventricular rhythm regular 3. Is there a P wave before each QRS? Are P waves upright and uniform? Yes Yes 4. What is the length of the PR interval? 0.12-0.20 seconds (3-5 small squares) 5. Do all QRS complexes look alike? What is the length of the QRS complexes? Yes 0.06-0.12 seconds (1 ½ to 3 small squares)

Sinus Bradycardia is defined as a regular but unusually slow heart rate, typically less than 60 beats per minute. The rhythm is characterized by regular atrial and ventricular rhythms, with upright and uniform P waves before each QRS complex. The PR interval falls within the range of 0.12-0.20 seconds, and the QRS complexes are uniform in appearance with a length of 0.06-0.12 seconds. Any deviations from these characteristics would indicate a different cardiac condition.

What is the length of the PR interval? 0.12-0.20 seconds (3-5 small squares) 5. Do all QRS complexes look alike? What is the length of the QRS complexes? Yes 0.06-0.12 seconds (1 ½ to 3 small squares)

4. What is sinus arrhythmia?

1. Sinus arrhythmia is a type of heart condition that requires urgent medical intervention.

2. Sinus arrhythmia is a rare genetic disorder that affects the heart's electrical system.

1. What is the rate? 60-100 beats per minute 2. What is the rhythm? Irregular (varies more than 0.08 sec) 3. Is there a P wave before each QRS? Are P waves upright and uniform? Yes Yes 4. What is the length of the PR interval? 0.12-0.20 seconds (3-5 small squares) 5. Do all QRS complexes look alike? What is the length of the QRS complexes? Yes 0.06-0.12 seconds (1 ½ to 3 small squares)

3. Sinus arrhythmia is a normal variation in the beating of your heart, but it always results in a fixed heart rate.

5. What is sinus arrest or pause defined as?

C. A regular rhythm with consistent P wave morphology.

A. The presence of abnormal P waves indicating a heart block.

1. What is the rate? Variable, depending on frequency 2. What is the rhythm? Irregular, when sinus arrest is present 3. Is there a P wave before each QRS? Are P waves upright and uniform? Yes, if QRS is present Yes, if QRS is present 4. What is the length of the PR interval? 0.12-0.20 seconds (3-5 small squares) 5. Do all QRS complexes look alike? What is the length of the QRS complexes? Yes, when present 0.06-0.12 seconds (1 ½ to 3 small squares)

B. A prolonged PR interval lasting more than 5 seconds.

Sinus arrest or pause is characterized by the transient absence of sinus P waves, which can last from 2 seconds to several minutes. It is not related to abnormal P waves, a prolonged PR interval, or a regular rhythm with consistent P wave morphology.
