Electrocardiographic Early Changes After Abdominoplasty

Abdominoplasty aims to reduce the abdominal excess tissue and tighten the abdominal wall. The tightening of the abdominal wall has structural and habitual consequences on the body, which might have an early effect on electrocardiography (ECG) of the patients through volumetric and pressure changes in thoracic and abdominal cavities. ECG serves as a diagnostic tool for assessing cardiac electrical conductions in routine clinical practice. In this study, we aimed to examine whether abdominoplasty has any discernible effect on early ECG results, with the goal of assessing potential cardiological benefits for the patients undergoing this procedure by comparing pre- and early postoperative ECGs.

Study population included 49 patients who had abdominoplasty. ECG records before the procedure and 12-24 h after the surgery were analyzed retrospectively. Patients had no known cardiac diseases and did not have any diagnosed arrhythmia.

The mean age of the study population was 37.1 ± 8.5. The mean body mass index of the study population was 26.4. The mean weight of total removed abdominal skin tissue was 1057 grams. There were significant changes in ECG of the patients postoperatively. Heart rate was increased, and significant change was found in QRS axis (p < 0.001) and T wave axis (p < 0.001). Atrial conduction parameters such as PR duration (p  < 0.001), Pmax duration (p  =  0.001) and P-wave dispersion (p = 0.003) were significantly changed postoperatively. Ventricular conduction parameters such as QRS duration (p = 0.029), QT interval (p   < 0.001), QTc (p  < 0.001), TPe duration (p < 0.001), TPe / QT (p < 0.001) and TPe / QTc (p < 0.001) ratios were found significantly changed.

Abdominoplasty changes the intra-abdominal pressure in the first 24 h after the surgery, which may impact cardiac conduction. The understanding and recognition of possible early ECG changes is crucial during postoperative follow-up of the patients who undergo abdominoplasty surgery.
