What causes Sinus Bradycadia?
-
The blockage of electrical conduction through the antrioventricular node
-
Increase in sinoatrial node impulse rate
-
Dysfunction of the sinoatrial node
-
Both A & C are common causes
-
Both B & C are common causes
Correct Answer
A. Dysfunction of the sinoatrial nodeExplanation
Sinus bradycardia is a condition characterized by an abnormally slow heart rate. In this case, the correct answer suggests that dysfunction of the sinoatrial (SA) node is the cause of sinus bradycardia. The SA node is responsible for initiating electrical impulses that regulate the heart rate. If the SA node is not functioning properly, it can result in a slower heart rate. This explanation is supported by the fact that the other options, such as blockage of electrical conduction through the atrioventricular (AV) node or an increase in SA node impulse rate, do not directly relate to dysfunction of the SA node.Rate this question:

During atrial flutter, the atrial beats could fire as many as how many times per minute?
-
230-350
-
100-140
-
100-250
-
More than 100 beats, less than 150
-
61-99
Correct Answer
A. 230-350Explanation
During atrial flutter, the atrial beats could fire as many as 230-350 times per minute. This is a condition where the atria of the heart beat rapidly and in a regular pattern. The normal heart rate is around 60-100 beats per minute, so a rate of 230-350 indicates a significantly increased and abnormal heart rate. This can lead to symptoms such as palpitations, shortness of breath, and dizziness. Treatment may be necessary to control the heart rate and prevent complications.Rate this question:

Identify the true statement(s) about Sinus tachycardia
-
It is usually a response to normal physiological situations, such as exercise and an increased sympathetic tone with increased catecholamine release—stress, fright, flight, anger.
-
P–R interval: Between 0.99–1.0 seconds and shortens with increasing heart rate
-
Beta blockers are a useful treatment option if the cause is sympathetic overactivity
-
Both A & C are true
-
It cannot be caused by an intake of stimulants such as caffeine
Correct Answer
A. Both A & C are trueExplanation
Sinus tachycardia is often a normal response to physiological situations like exercise or increased sympathetic tone with increased catecholamine release, such as stress, fright, flight, or anger. The P-R interval is typically between 0.99-1.0 seconds and shortens as the heart rate increases. Beta blockers can be an effective treatment if the cause of sinus tachycardia is sympathetic overactivity. Additionally, both statement A and statement C are true.Rate this question:

-
Respiratory sinus arrhythmia
-
Atrial fibrillation
-
Ventricular fibrillation
-
Premature Atrial Complex
-
None of the above
Correct Answer
A. Respiratory sinus arrhythmiaExplanation
The image above shows respiratory sinus arrhythmia. This is indicated by the irregular pattern of the heart rate, which varies with respiration. During inspiration, the heart rate increases, and during expiration, it decreases. This type of arrhythmia is commonly seen in healthy individuals, especially during deep breathing or relaxation. It is not a cause for concern and does not require treatment.Rate this question:

In sinus arrhythmia, the heart rate is a variable depending on...?
-
Inspiration
-
Expiration
-
Respiration
Correct Answer
A. RespirationExplanation
In sinus arrhythmia, the heart rate varies depending on the phase of respiration, specifically on inspiration and expiration. Sinus arrhythmia is characterized by a slight variation in the heart rate that corresponds to the respiratory cycle: the heart rate tends to increase slightly during inspiration and decrease during expiration. This phenomenon is more pronounced in younger individuals and is considered a normal variation.Rate this question:

How is Premature Atrial Contraction typically diagnosed?
-
Electrocardiogram
-
Holter Monitor
-
Cardiac Event Monitor
-
All of the above
-
None of the above
Correct Answer
A. All of the aboveExplanation
Premature Atrial Contraction (PAC) is typically diagnosed through various methods, including an Electrocardiogram (ECG), Holter Monitor, and Cardiac Event Monitor. An ECG is a non-invasive test that records the electrical activity of the heart, which can help identify abnormal heart rhythms like PAC. A Holter Monitor is a portable device worn by the patient for 24 to 48 hours to continuously monitor the heart's electrical activity and detect any irregularities. Similarly, a Cardiac Event Monitor is a portable device that can be worn for a longer period, typically up to 30 days, to record the heart's activity and capture any abnormal events. Therefore, all of these methods can be used to diagnose PAC.Rate this question:

Atrial Flutter is categorized as Type 1 Atrial Flutter or Type II Atrial Flutter. Which statement below accurately describes Type II?
-
It is known as clockwise or counterclockwise atrial flutter depending on the loop
-
It is usually faster than Type 1-340-440 beats per minute
-
It follows a significantly different re-entry pathway than Type I flutter
-
The reentrant loop circles the right atrium and passes through cavo-tricsupid isthmus
-
Both B&C
Correct Answer
A. Both B&CExplanation
Type II Atrial Flutter is usually faster than Type I, with a heart rate ranging from 340-440 beats per minute. Additionally, it follows a significantly different re-entry pathway compared to Type I flutter. The reentrant loop in Type II Atrial Flutter circles the right atrium and passes through the cavo-tricuspid isthmus. Therefore, the correct answer is that both statements B and C accurately describe Type II Atrial Flutter.Rate this question:

What makes Atrial fibrillation difficult to diagnose?
-
It may cause no symptoms
-
Screening is not generally performed
-
It is not clear what AF should be called
-
All of the above
-
A&B only
Correct Answer
A. A&B onlyExplanation
Atrial fibrillation (AF) is difficult to diagnose because it may cause no symptoms, making it challenging for individuals to recognize that they have the condition. Additionally, screening for AF is not generally performed, which further contributes to the difficulty in diagnosing the condition. It is not clear what AF should be called, which can also lead to confusion and challenges in diagnosing the condition accurately. Therefore, the correct answer is A&B only.Rate this question:

-
Rapid heart rate
-
The presence of chest pain or angina
-
Weight loss and diarrhea
-
All of the above
-
None of the above
Correct Answer
A. All of the aboveExplanation
Atrial fibrillation is a heart condition characterized by an irregular and often rapid heart rate. This can lead to symptoms such as palpitations, shortness of breath, and fatigue. In some cases, individuals with atrial fibrillation may also experience chest pain or angina. Weight loss and diarrhea are not typically associated with atrial fibrillation, so the correct answer is "None of the above."Rate this question:
-

True or false: A history of stroke or TIA, as well as hypertension (high blood pressure), diabetes, heart failure and rheumatic fever, may indicate whether someone with AF is at a higher risk of complications
-
True
-
False
Correct Answer
A. TrueExplanation
A history of stroke or TIA (Transient Ischemic Attack) indicates that there has been a disruption in blood flow to the brain, which can be a complication of atrial fibrillation (AF). Hypertension, diabetes, heart failure, and rheumatic fever are all conditions that can increase the risk of developing AF or exacerbate its symptoms. Therefore, if someone with AF also has any of these conditions, they may be at a higher risk of complications.Rate this question:

True or False: Occassional Premature Atrial Contractions are a common and normal finding in otherwise healthy patients and DO NOT indicate any particular health risk.
-
True
-
False
Correct Answer
A. TrueExplanation
Occasional premature atrial contractions (PACs) are indeed a common and normal finding in otherwise healthy patients. PACs refer to early electrical impulses originating from the atria of the heart. They are usually harmless and do not indicate any specific health risk. However, if PACs become frequent or are associated with other heart conditions, further evaluation may be necessary. Overall, the statement that occasional PACs do not indicate any particular health risk is true.Rate this question:

Ventricular tachycardia
-
Ventricular fibrillation
-
Sinus Bradycardia
-
Sinus arrhythmia
-
None of the above
Correct Answer
A. Ventricular tachycardiaExplanation
The given strip shows a rapid heart rate with wide QRS complexes, indicating a ventricular origin. This is consistent with ventricular tachycardia, which is a potentially life-threatening arrhythmia characterized by abnormal electrical activity in the ventricles. Ventricular tachycardia can lead to decreased cardiac output and can degenerate into ventricular fibrillation if not promptly treated.Rate this question:

-
None of the above
Correct Answer
A. Ventricular FibrillationExplanation
The correct answer is Ventricular Fibrillation. Ventricular fibrillation is a life-threatening arrhythmia characterized by rapid and disorganized electrical activity in the ventricles of the heart. It is typically associated with a lack of coordinated contractions of the ventricles, leading to ineffective pumping of blood. This condition can result in cardiac arrest and requires immediate medical intervention, such as defibrillation, to restore a normal heart rhythm.Rate this question:

Ventricular tachycardia is a potentially life threatening arrhythmia because it may lead to....?
-
Ventricular fibrillation
-
Asytole
-
Death
-
All of the above
-
A&C only
Correct Answer
A. A&C onlyExplanation
Ventricular tachycardia is a potentially life-threatening arrhythmia because it may lead to ventricular fibrillation and death. Ventricular fibrillation is a chaotic, irregular heartbeat that prevents the heart from pumping blood effectively, leading to a lack of oxygen supply to the body's organs. As a result, if left untreated, ventricular fibrillation can quickly lead to cardiac arrest and death. Therefore, the correct answer is A&C only, as ventricular tachycardia can potentially progress to ventricular fibrillation and result in death.Rate this question:
