title: Evaluation of radiation dose during pacemaker implantations.
abstract: The purpose was to evaluate patient radiation doses and compare with other interventional procedures. One hundred and twenty-eight procedures were carried out with a recently installed mobile undercouch C-arm machine with a 23-cm diameter image intensifier. The radiation dose is provided by the X-ray machine, in terms of cumulative dose (CD). Kerma-Area product (KAP) was then estimated from CD and the X-ray field size. Other patient parameters recorded were patient weight, age, kilovolt, milliampere and fluoroscopy time (T). Median (range) CD, KAP and T were 15.2 mGy (3.2-110 mGy), 6.3 Gy cm(2) (1.3-45.7 Gy cm(2)) and 5.2 (1.5-27.4 min) min, respectively. Median E was 1.1 mSv (conversion factor: 0.18 mSv per Gy cm(2)), which corresponds to approximately one lumbar spine X-ray radiography. The effective dose is much lower than a coronary angiography (8 mSv) or an electrophysiology study (6 mSv). Radiation dose is low compared with other interventional cardiology procedures.
