Follow-up strategy
Following discharge, it was recommended that patients undergo at least
one cardiac rhythm evaluation through electrocardiography (ECG) or
24-hour Holter monitoring at the 1-month mark post-procedure, and a
transthoracic echocardiography 3 months afterwards to check for
abnormalities in the left ventricular end-diastolic diameter (LVEDD) or
left ventricular ejection fraction (LVEF).
For the purpose of this study, we contacted patients to gather current
symptomatology, the outcomes from ECG and 24-hour Holter monitoring, the
most recent measurements of LVEDD and LVEF, post-CA complications,
incidences of rehospitalization, and details regarding pharmacotherapy.
Baseline data, including patient demographics, PVC burden, time elapsed
since initial diagnosis, history of pharmacotherapy, and cardiovascular
history, were extracted from the electronic medical records system.
Antiarrhythmic drugs were categorized according to the updated
classification system10, and traditional Chinese
medicine treatments such as Shensong Yangxin11capsules and Wenxin Keli12 were also accounted for.
