Abstract:
This case report presents a 26-year old male patient brought to the
medical ward with an experience of repeating blackout for a year. The
patient was diagnosed with sick sinus syndrome, and further
investigations revealed left isomerism, polysplenia, and no congenital
heart defects. Holter monitoring, ultrasonography, electrocardiography,
and computed tomography were used to confirm the diagnosis. The patient
underwent DDDR pacemaker implantation for the treatment of SA node
dysfunction. The report highlights the variability of anatomical
findings associated with polysplenia pattern and the various types of
heartbeat disruptions that may occur in the atrial appendages of the
left side isomerism.
