Identify the following Cardiac Rhythm:<\/strong><\/p>\n\n\n\n

A.

D.

The correct answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer depends on the characteristics of the cardiac rhythm you’re describing, but based on the given options, let’s explain them to identify the most likely rhythm.<\/p>\n\n\n\n

Sinus Tachycardia<\/h3>\n\n\n\n

Sinus tachycardia is a normal sinus rhythm where the heart rate is elevated, typically between 100 and 150 beats per minute. P waves are present before each QRS complex, and the PR interval is normal (0.12-0.20 seconds). The QRS complex duration remains within normal limits. This rhythm is often seen during exercise, anxiety, or as a response to fever or dehydration.<\/p>\n\n\n\n

Ventricular Tachycardia (VT)<\/h3>\n\n\n\n

Ventricular tachycardia is a life-threatening rhythm characterized by wide, bizarre QRS complexes, with a rate typically between 100 and 250 beats per minute. It arises from the ventricles, bypassing the normal conduction system. P waves are often absent or not related to the QRS complex (AV dissociation), and the rhythm can be monomorphic (consistent morphology of QRS complexes) or polymorphic (varying QRS morphology). This rhythm requires immediate medical intervention as it can degenerate into ventricular fibrillation.<\/p>\n\n\n\n

Complete Heart Block (Third-Degree AV Block)<\/h3>\n\n\n\n

In complete heart block, the atria and ventricles beat independently of each other. There is no communication between P waves and QRS complexes, resulting in AV dissociation. The atrial rate (P wave) is normal but unrelated to the ventricular rate, which is typically slower, governed by a junctional or ventricular escape rhythm. The QRS complexes can be narrow or wide, depending on the origin of the escape rhythm.<\/p>\n\n\n\n

Idioventricular Rhythm<\/h3>\n\n\n\n

Idioventricular rhythm is a ventricular escape rhythm with a rate between 20 and 40 beats per minute. P waves are typically absent, and the QRS complexes are wide and abnormal in appearance. This rhythm can occur in the setting of a complete heart block or as a “slow” ventricular escape rhythm after the failure of higher pacemakers.<\/p>\n\n\n\n

Conclusion:<\/h4>\n\n\n\n

Without an ECG to analyze, ventricular tachycardia<\/strong> (Option B) is most likely when rapid, wide QRS complexes are present and there is no clear atrial activity.<\/p>\n","protected":false},"excerpt":{"rendered":"
