ABSTRACT
<p><b>OBJECTIVE</b>To evaluate factors for predicting ventricular arrhythmia, the clinical effect of drugs on patients with catecholaminergic polymorphic ventricular tachycardia (CPVT), and their long-term outcomes.</p><p><b>METHODS</b>Six patients diagnosed with CPVT underwent a series of electrocardiograms and 24-hour Holter monitoring. β-blockers were recommended for all patients, while some patients were also prescribed propafenone and 1 patient underwent catheter-based renal sympathetic denervation (RDN). The characteristics of electrocardiogram, arrhythmia and long-term outcomes were monitored.</p><p><b>RESULTS</b>Syncope episodes did not occur any longer in 1 patient on β-blocker, but recurred in 3 other patients and 2 patients died (one due to his cessation of metoprolol for 3 months). Inverted and/or bifid T waves and abnormal U wave were observed in the precordial leads. T wave alternans was observed in 4 patients in the precordial leads. These abnormal electrocardiogram features disappeared or diminished with β-blocker treatment. All spontaneous episodes of ventricular tachycardia occurred prior to sinus tachycardia and frequent polymorphic premature ventricular contractions.</p><p><b>CONCLUSIONS</b>Bifid and/or inverted T waves, T wave alternans and abnormal U waves together with sinus tachycardia and frequent premature ventricular contractions are indicator for predicting ventricular arrhythmia and assessing the effect of β-blockers. Compliance with β-blocker treatment is a strong indicator of outcome.</p>

<p><b>OBJECTIVE</b>To describe the clinical features of 6 patients with catecholaminergic polymorphic ventricular tachycardia.</p><p><b>METHODS</b>Clinical data including signs and symptoms, electrocardiograms, Holter monitoring electrocardiograms and echocardiography was analyzed. Definite diagnosis was made based on the mutations of RYR2 and CASQ2.</p><p><b>RESULTS</b>From July 2002 to March 2010, 6 consecutive patients referred to our center because of syncope [4 males, mean age (13.0 ± 4.2) years] were diagnosed with CPVT by clinical evaluation and genetic testing. Their electrocardiograms showed T waves with notch or bimodal and tall U waves in right chest leads. There was no J wave, no ST-segment deviation, no prolongation or shortening of QT interval. We captured the so-called "bidirectional and(or) polymorphic ventricular tachycardia (bVT and pVT)" in 2 out of 6 patients by ECG, in 5 out of 6 patients by 24-hours Holter monitor, in 3 out of 6 patients by exercise test. All patients received β blockers and no syncope occurred during the 3 months follow-up after discharge from hospital.</p><p><b>CONCLUSIONS</b>CPVT is an inherited cardiac channelopathy characterized by syncope and(or) sudden death relatived to motion. The ECG shows T wave alteration and tall U wave in right chest leads. The mode of its onset is bVT and(or) pVT, and can be captured by Holter easily. β blocker is a safe and effective remedy for suppressing its attack.</p>

<p><b>OBJECTIVE</b>To investigate the method and clinical outcome of reconstructing large pulp defects of the fingertips with a homodigital neurovascular island flap.</p><p><b>METHODS</b>Form June 2007 to October 2009, 16 patients with the defects of pulp were repaired by the spiral flap that was a homodigital neurovascular island flap with a unique spiral advancement and transposition design allowed pulp reconstruction using sensate glabrous skin while restricting donor morbidity to the injured digit. There were 12 males and 4 females with an average age of 37 years ranging from 18 to 49 years. The defect were caused by machine crush injury 11 cases, pressure injury by heavy objects in 2 cases, crush injury by door of car 1 case, injury by saw in 2 cases. The defect was located in the index finger in 5 cases, the middle finger in 9 cases,the ring finger in 2 cases. All injuries had large pulp defects averaging 1.6 cm (long) x 1.2 cm (wide) to 2.5 cm (long) x 1.7 cm (wide). Short-term results for all patients were reviewed. Outcome measures included static 2-point discrimination, total active motion, and hypersensitivity or cold intolerance.</p><p><b>RESULTS</b>All flaps achieved primary healing with no complications. Sensory recovery was excellent with an average 2-point discrimination of 5.1 mm. All patients were followed-up for 8 to 20 months (averaged 12 months) with highly satisfactory with both aesthetic and functional outcome. There was no hypersensitivity or cold intolerance. According to the evaluation of total active motion (TAM) scales, the results were excellent in 7 cases, good in 8 cases (9 lesions) and fair in 1 case.</p><p><b>CONCLUSION</b>The spiral advancement-transposition flap is suitable for resurfacing large pulp defects with excellent short-term functional and aesthetic results and high patient satisfaction.</p>
