Aberrant intraventricular conduction and reciprocal beats. Two case reports

Area of Science:

• Cardiology
• Electrophysiology

Background:

• Supraventricular tachycardias (SVT) with aberrant intraventricular conduction can mimic ventricular tachycardias (VT).
• Accurate differentiation is crucial for appropriate patient management.

Observation:

• Two cases are presented where SVT with aberrant conduction was misdiagnosed as VT.
• Key clinical and electrocardiographic signs suggestive of ventricular aberrancy were overlooked.

Findings:

• Misinterpretation of supraventricular rhythm disturbances with aberrant conduction led to diagnostic confusion.
• Therapeutic decisions were negatively impacted by the initial misdiagnosis.

Implications:

• Highlights the importance of recognizing signs of ventricular aberrancy in supraventricular rhythm disturbances.
• Emphasizes the need for careful electrocardiographic interpretation to avoid therapeutic errors in cardiac arrhythmias.
