Cardiac Arrhythmia Diagnostic Skills Quiz

The correct approach to rhythm analysis involves looking for specific criteria related to the P waves, QRS width, regularity of rhythm, P-QRS relationship, and heart rate. The other options do not address the key components of rhythm analysis.

Lead II is commonly used for rhythm analysis due to its orientation and ability to capture specific electrical activity of the heart.

Supraventricular rhythms originate above the ventricles and typically have a P wave on an ECG, whereas ventricular rhythms originate in the ventricles and usually do not show a distinct P wave.

When a rhythm originates in the AV node, there will be no P wave and the QRS complex is usually narrow. This is due to the normal conduction pathway that the impulse follows when originating from the AV node.

When the rhythm originates in the ventricle, there is no P wave present as the electrical impulse doesn't travel through the atria. The QRS complex is wide as it denotes ventricular depolarization.

The question is asking for the description of rhythm arrhythmias and PR interval. The correct answer is NSR or Normal Sinus Rhythm, which signifies a normal heart rhythm. Sinus bradycardia refers to a slow heart rate, sinus tachycardia is a fast heart rate, and sinus arrhythmia is an irregular heart rhythm.

Supraventricular arrhythmias are abnormal heart rhythms that originate above the ventricles, typically in the atria or the atrioventricular (AV) node. The incorrect answers provided do not accurately represent the origins of supraventricular arrhythmias.

Atrial fibrillation (A fib) is characterized by an irregularly irregular rhythm, meaning there is no discernible pattern to the irregularity of the heartbeats. The other incorrect answers do not accurately describe the unique rhythm of A fib.

A strip and pharm refers to atrial fibrillation (A fib) with rapid ventricular response. The correct treatment includes intravenous administration of diltiazem, beta blockers like metoprolol or Esmolol, or amiodarone to control the heart rate.

The correct treatment for A fib includes IV diltiazem, IV beta blocker(metoprolol or Esmolol), or IV amiodarone to manage the arrhythmia effectively.

A patient with AFib with RVR typically presents with an irregularly irregular heart rate, palpitations, chest discomfort, shortness of breath, and possibly syncope. The correct approach involves using IV medications such as diltiazem, beta blockers, or amiodarone to control the rapid ventricular rate.

Non-pharmacological treatments for atrial fibrillation involve procedures such as radiofrequency ablation to correct aberrant pathways, cardioversion followed by antiarrhythmic therapy. Starting a new medication regimen, surgical removal of the atrial appendage, and pacemaker implantation are not typically used to treat atrial fibrillation non-pharmacologically.

In patients with atrial fibrillation lasting more than 48 hours, the main concern when restoring sinus rhythm is the risk of thromboembolism. This is due to the potential for blood clots to form in the atria during the period of atrial fibrillation, which can dislodge and cause blockages in other parts of the circulatory system.

Atrial flutter is characterized by a rapid, regular atrial rhythm, different from atrial fibrillation which is irregular. Sinus tachycardia is a normal increase in heart rate, while supraventricular tachycardia is a broad term that encompasses various types of fast heart rhythms originating above the ventricles.

Atrial flutter is characterized by a saw tooth pattern in the inferior leads on an ECG. This appearance is due to the rapid atrial depolarizations causing a distinctive flutter wave.

Inferior leads in an ECG refer to leads that view the inferior part of the heart. These leads include leads II, III, and aVF.

A-Flutter (Atrial Flutter) is a type of abnormal heart rhythm characterized by a 'Saw-tooth' pattern on an EKG. The correct pharmacological treatment includes options such as IV diltiazem, IV beta blocker (metoprolol or Esmolol), or IV amiodarone to help control the heart rate and restore normal rhythm.

The correct answer describes atrial flutter and provides appropriate treatments for it. The incorrect answers do not match the description of the strip or the treatment provided.

Strip and treatment refers to the management of Aflutter, a type of abnormal heart rhythm. The correct treatment options include IV diltiazem, IV beta blockers, or IV amiodarone to help control the heart rate and rhythm.

A-flutter refers to atrial flutter, a cardiac arrhythmia characterized by a fast but regular heartbeat. While pharmacological treatments such as beta-blockers and calcium channel blockers may be used in stable patients, the non-pharmacological approach of D-C cardioversion is typically reserved for those who are hemodynamically unstable and require immediate intervention to restore normal heart rhythm.

The correct answer refers to a type of abnormal heart rhythm involving the upper chambers of the heart. The incorrect answers do not accurately describe 'strip and treatment' in the context of medical terminology.

Paroxysmal supraventricular tachycardia (PSVT) is a narrow complex tachycardia that originates above the ventricles. It typically presents with a heart rate of 170-250 beats per minute and can manifest as a regular or irregular rhythm. Ventricular tachycardia, atrial fibrillation, and sinus tachycardia are different types of cardiac arrhythmias that would usually present with different ECG findings compared to PSVT.

The correct answer describes a situation of narrow QRS complex, high heart rate, and the actions of massage carotid and administering Adenosine in specific doses. The incorrect answers provide different scenarios with varying ECG findings, heart rates, and treatment plans to confuse test-takers.

The correct answer describes the characteristics of PSVT, which include a narrow QRS complex, heart rate between 170-250 beats per minute, and regular or irregular rhythm in slides 33 and 34.

PSVT is a condition characterized by rapid heart rates originating above the ventricles. The correct treatment approach involves either DC cardioversion in cases of hemodynamic instability or vagal maneuvers along with the administration of adenosine if the patient is stable. The incorrect answers do not align with the standard management of PSVT.

Ventricular Dysrhythmia is a type of abnormal heart rhythm that originates in the lower chambers of the heart (ventricles), leading to a wide QRS complex on an ECG. Supraventricular Tachycardia, Atrial Fibrillation, and Sinus Bradycardia are different types of heart rhythms with distinct characteristics.

This question tests your knowledge of different cardiac rhythms and their treatments. In this case, the correct answer is a form of escape rhythm with a specific heart rate, while the incorrect answers include other common cardiac rhythms.

Vtach stands for Ventricular Tachycardia, a potentially life-threatening heart rhythm abnormality that requires immediate medical intervention.
