Question

identify this rhythm

sinus tachycardia
sinus rhythm with pvcs
supraventricular tachycardia
junctional tachycardia
sinus rhythm with pjcs

Explanation:

Analyze the underlying rhythm

The baseline rhythm shows regular, narrow QRS complexes preceded by upright P waves in this lead, indicating a underlying sinus rhythm.

Identify ectopic beats

Two wide, bizarre QRS complexes occur prematurely (the second and fifth complexes). These complexes lack preceding P waves and are followed by a compensatory pause.

Classify the rhythm

The premature, wide, and distorted QRS complexes are characteristic of Premature Ventricular Contractions (PVCs) occurring on a background of sinus rhythm.

Answer:

• Sinus Tachycardia
• Sinus Rhythm with PVC's (Correct answer)
• Supraventricular Tachycardia
• Junctional Tachycardia
• Sinus rhythm with PJC's
