When Trabeculations Disrupt Conduction: Left Ventricular Noncompaction Presenting With Symptomatic Bradycardia and Isorhythmic Dissociation

Key Result

Left ventricular noncompaction should be considered in young patients with unexplained symptomatic bradycardia, requiring precise ECG interpretation to distinguish AV dissociation from true AV block.

Key Points

• To investigate the potential diagnosis of left ventricular noncompaction (LVNC) in young patients with unexplained symptomatic bradycardia.
• Evaluated young patients presenting with symptomatic bradycardia.
• Performed precise ECG interpretation to distinguish between AV dissociation and true AV block.
• Considered further interventions like cardiac MRI and genetic evaluation based on findings.
• Identified LVNC as a relevant condition in cases of unexplained bradycardia.
• Found that distinguishing AV dissociation from true AV block guides appropriate therapy decisions.
• Recommendation for patients with LVNC to undergo cardiac MRI and genetic evaluation to assess risks.
