• Arrhythmias

• ECGs

Multiple Select

• Palpitations

• Dizziness

• Chest pain

• Fatigue

Multiple Select

What are the possible causes and emergency management of sinus bradycardia?

• Increased vagal tone

• Medications

• Heart block

• Dehydration

Multiple Choice

What are the ECG characteristics of a sinus rhythm?

• Regular rhythm

• Variable heart rate

• Wide QRS complex

• Absent P waves

Multiple Choice

The place where the electrical current starts and is considered the heart's pacemaker:

• Sino-atrial node 
• right atrium
• atria-ventricular node 
• left ventricle

Multiple Choice

What is the function of the Sinus node in the heart's electrical conduction system?

• To initiate the heartbeat

• To delay the electrical signal

• To conduct signals to the ventricles

• To regulate blood pressure

Multiple Choice

What are the characteristics of a rhythm that begins in the SA node?

• Positive P wave before each QRS complex

• Irregular PR interval

• P waves that look different

• Atrial and ventricular rhythm are irregular

Multiple Choice

What is the normal heart rhythm that reflects normal electrical activity?

• Sinus rhythm

• Atrial fibrillation

• Ventricular tachycardia

• Bradycardia

Multiple Choice

What is the definition of Sinus Bradycardia?

• A heart rate less than 60 beats per minute

• A heart rate greater than 100 beats per minute

• A normal heart rate between 60-100 beats per minute

• A heart rate that varies with breathing

Multiple Choice

What are the potential causes of Sinus Bradycardia?

• Disease of the SA node

• Hypothermia

• Obstructive sleep apnea

• Post heart transplant

Multiple Choice

What is the condition characterized by an increased heart rate, often defined as a resting heart rate over 100 beats per minute?

• Bradycardia

• Atrial Fibrillation

• Sinus Tachycardia

• Ventricular Tachycardia

Multiple Choice

What is sinus tachycardia?

• A condition where the heart rate is slower than normal

• A condition where the heart rate is faster than normal

• A condition that only occurs in children

• A condition that affects the heart's structure

Multiple Choice

What is the characteristic feature of sinus tachycardia as shown in the ECG strip?

• Regular rhythm

• Irregular rhythm

• Wide QRS complexes

• Shortened PR interval

Multiple Choice

What is Inappropriate Sinus Tachycardia (IST)?

• A condition with no apparent physiologic cause

• A heart rate that is always below 100 beats/min

• A diagnosis made without ruling out other causes

• A condition that only occurs during exercise

Multiple Choice

What is the definition of Sinus Arrhythmia?

• A type of heart rhythm that is irregular

• A condition where the heart beats too fast

• A condition where the heart beats too slow

• A normal heart rhythm

Multiple Choice

What is the characteristic feature of sinus arrhythmia as shown in the ECG?

• Regular rhythm

• Irregular rhythm

• P waves present

• QRS complex absent
