Example 1, female, 64 years old. Due to paroxysmal palpitation three years, the onset of 6 hours in August 1980 admitted. Three years ago, there was no obvious incentive for patients with palpitation, beginning and ending suddenly. Almost a year episodes frequently, each lasting a few minutes to several hours, and more able to ease itself, confirmed by multiple electrocardiographic ventricular tachycardia, the onset of 6 hours can not be alleviated. In the past no high blood pressure, precordial pain history. Physical examination: Bp80 / 60, pale, apathetic expression, heart rate 160 times, law Qi, the heart bound to expand on both sides, no pathological murmur. Assay: hemoglobin 7.5g, cholesterol 280mg / dl.β-ester protein 580mg%, triglyceride 150mg%, ECG showed supraventricular tachycardia, intermittent seizures showed sinus bradycardia, ST depression 0.05mv, T wave low flat. Echocardiography showed pericardial effusion. ~ (131) I: 7% in 2 hours, 8% in hours and 4% in 24 hours. T_3 62.4 ng%, T_4 <1.5 μg. After the diagnosis of thyroxine tablets 20mg, 3 times a day. One week later, the number of episodes of supraventricular tachycardia was significantly reduced, thyroxine tablets increased to 40 mg-day2
