本例心电图起始和终末均可见规律的窦性P波,频率约88次/min,其后可见自身顺传或起搏的QRS波群(R_1~R_2及R_(12)~R_(14)),R_2~R_(11)之间未见窦性P波,提示存在窦性停搏。R_3~R_(13)均为心室起搏,其中R_3、R_5、R_7、R_9及R_(11)频率60次/min,其前未见P波或心房起搏信号,T波中可见倒置的P-波,提示为心室起搏逆传产生;R_4、R_6、R_8、R_(10)、R_(12)及R_(13)前均可见P波(窦性P波
In this case, we can see the regular sinus P wave at the beginning and the end of the electrocardiogram at a frequency of about 88 beats / min, followed by QRS complex (R_1 ~ R_2 and R_ (12) ~R_14 )), No R sinusoidal P wave was found between R_2 and R_ (11), suggesting the presence of sinus arrest. R_3 ~ R_ (13) were ventricular pacing, of which R_3, R_5, R_7, R_9 and R_ (11) frequency of 60 beats / min, no P wave or atrial pacing signal in the previous, T wave can be seen inverted P - wave, prompted by retrograde ventricular pacing; P wave (sinus P wave was seen before R_4, R_6, R_8, R_ (10), R_ (12) and R_ (13)
