Association of Antimitochondrial Antibody With Right Atrial Low Voltage and Sick Sinus Syndrome

Key Points

• To explore the relationship between antimitochondrial antibody positivity, right atrial low voltage, and sick sinus syndrome.
• Case observations
• Assessment of right atrial voltage levels
• Evaluation of sick sinus syndrome symptoms
• Identified a potential association between AMA positivity and low voltage in the right atrium.
• Noted occurrences of sick sinus syndrome alongside AMA positivity.
• Observed that left ventricular dysfunction was not present in these cases.
