Method
Study site: This is a retrospective analysis of all
patients who underwent CSD at a tertiary hospitalfrom January 2010 to
June 2019.
Data compilation: Data was collected from all patients
during their index hospitalization, out-patient visit charts, telephonic
conversation, hospital records, telemetry and ICD interrogation details
(wherever available). Apart from patient demographics, the type of
ventricular arrhythmia, etiology of ventricular arrhythmia, medication
details, thoracic epidural anesthesia (TEA), immediate peri-CSD
outcomes, procedural complications and follow-up data were noted. In
case the patients did not come for follow-up, they were contacted
telephonically at regular intervals.
