Her medical historyincluded arterial hypertension and diabetes. She was nottaking any negative chronotropic drugs but she referred afhmilial history of fhtal pulmonary embolism and suddencardiac death. At admission, blood pressure, pulse rate andperipheral oxygen saturation were 88/60 mmHg.展开更多

This bradycardia may be due to vagally mediated cardio-biliary reflex. Many of these reflexes due to acute cholecystitis have similar clinical features (some electrocardiographic changes like bradycardia, complete heart block, and asystole) mimicking that of acute coronary syndrome. Patient's concern: A 60-year old male presented with symptoms of acute cholecystitis and referred to the emergency department with complete heart block and abdominal pain with hypotension requiring an emergency temporary pacemaker. Diagnosis: Cope's sign and complete heart block. Intervention: Emergency temporary cardiac pacemaker insertion. Outcomes: The patient was discharged after three days with regular follow-up and advice for laparoscopic cholecystectomy. Lessons: Complete heart block or any symptomatic bradycardia associated with abdominal pain should be under consideration of cholecystitis that may be associated with either presence or absence of gall stones due to cardio biliary reflex.展开更多

Prophylactic temporary pacemaker insertion is associated with well-defined risks, and less invasive techniques exist to treat transient, hemodynamically significant intraoperative brady-arrhythmias. The present case report details the performance of general anesthesia for arthroscopic knee surgery in an adult patient with this condition without a pacemaker. Documentation of preoperative chronotropic competence with isoproterenol may be of value in deciding whether to proceed without temporary pacing capability in this setting.展开更多

Their clinical presentation may range from being asymptomatic as an incidental finding on cardiac imaging to symptomatic presentations related to the compression of adjoining structures or intracardiac shunting caused by rupture of the SOVA mostly into the right side of the heart. The compression leads to findings of tricuspid valve regurgitation, right ventricular outflow tract (RVOT) obstruction and rarely complete heart block (CHB). Dissection or erosion into interventricular septum is one of the rarest complications of SOVA. The symptomatic presentation is almost always a surgical emergency. Here we present a case report of a patient with unruptured sinus of valsalva originating from right sinus dissecting into interventricular septum causing complete heart bock. In this case after surgical correction the complete heart block reverted to sinus rhythm.展开更多

It was on May 29, 1959, when the late Premier Zhou Enlai came to visit Dr. Yu’s laboratory during his inspection tour at the Tianjin University. This has been an unforgettable event in Prof. Yu’s mind. When shaking hands with Prof. Yu, Premier Zhou said: "I heard that you have made great advances in the rescarch of heavy water. I am eagerly waiting for further success in your work. For the honor of our country, we must have heavy water developed with our own hands, in defiance of someone who attempts to strangle us." Looking into the Premier’s eyes of encouragement,Prof. Yu was then determined to live up to the expectations of the motherland by making a good job of his research work.展开更多
