Female patient, 72 years old, has a history of sinus bradycardia for 28 years, had multiple syncope and was diagnosed as “sick sinus syndrome.” Due to fatigue and weakness January was admitted to hospital on June 28, 1990. Physical examination: blood pressure 14.7 ~ 17.3 / 7.9 ~ 9.3kPa (110 ~ 130/60 ~ 70mmHs), extended to the left heart sound boundary (1cm outside the midline of the clavicle), heart sound more powerful, heart rate 40 beats / Before the area can be heard Ⅱ ~ Ⅲ systolic murmur, I no exception. X-ray: heart diameter 16cm, cardiothoracic ratio 0.55, heart shadow left to expand. Echocardiography examination of each cavity diameter: ascending aorta 31mm, left atrium 40mm, left ventricular 46mm, interventricular septum thickness 9mm, left ventricular posterior wall thickness 9mm, aortic 21mm, right atrium 33mm, right ventricular 34mm, mitral regurgitation (Mild). Cardiac electrophysiological examination: sinus node dysfunction, atrioventricular node function potential decline, no room conduction.
