We evaluated the efficacy of a new method for recording electrocardiogram (ECG) of pacemaker patients in bathtub (bathtub ECG). ECG from the pacemaker implanted patients in the bathtub with tap water was recorded through three silver/silver chloride electrodes (4 x 4 cm) fitted on the inside wall of bathtub. Electric signal was connected to the isolated amplifier and recorded on the strip chart recorder. Contrast to the conventional method for recording standard ECG, bathtub ECG does not require body surface electrodes and is recorded at patients home. Although the amplitude of bathtub ECG was reduced approximately to a quarter of standard ECG, cardiac arrhythmia can be easily interpreted by bathtub ECG. In patients with pacemaker system, the amplitude of the pacing pulse recorded by bathtub ECG was much larger than that of QRS complex recorded by standard ECG. Therefore, we conclude that bathtub ECG would be a suitable method to follow up patients with pacemaker system.
我们评估了一种在浴缸中记录起搏器患者心电图（ECG）的新方法（浴缸心电图）的有效性。通过安装在浴缸内壁的三个银/氯化银电极（4×4厘米）记录在浴缸中装有自来水的起搏器植入患者的心电图。电信号连接到隔离放大器并记录在带状图表记录仪上。与记录标准心电图的传统方法相比，浴缸心电图不需要体表电极，且在患者家中即可记录。尽管浴缸心电图的幅度大约降低到标准心电图的四分之一，但心律失常仍可通过浴缸心电图轻松解读。在起搏器系统患者中，浴缸心电图记录的起搏脉冲幅度远大于标准心电图记录的QRS波群幅度。因此，我们得出结论，浴缸心电图将是随访起搏器系统患者的合适方法。
