Seven patients had chronic, unexplained, nonparoxysmal sinus tachycardia. The clinical, electrocardiographic, and electrophysiologic characteristics of these cases are described. In each case electrocardiographic and electrophysiologic observations suggested that tachycardia was nonparoxysmal and due to increased automaticity of the sinus node (or of an(More)
Our results indicate the following. 1. HRV is markedly depressed in inducible SCD survivors, a group at high risk of a subsequent episode of SCD. 2. Studies on patients who developed SCD during Holter monitoring indicate that HRV is depressed prior to SCD. 3. HRV is markedly depressed in inducible "asymptomatic ventricular ectopy" patients, with the degree(More)
Right coronary artery (RCA) occlusion and acute myocardial infarction are rare during radiofrequency (RF) ablation of the cavotricuspid isthmus. Ventricular fibrillation (VF) or cardiac arrest in the periprocedural period may be the initial or only clinical manifestation. Septal or lateral RF delivery may increase the risk. We report 2 cases of RCA(More)
OBJECTIVES To define current clinical practice of lithium prescribing and monitoring and to compare hospital based practice with general practice. DESIGN Prospective study of doctors' practice. SETTING Psychiatric hospital day and outpatient facilities and general practices in Edinburgh and Midlothian district (population 600,000). SUBJECTS 458(More)
The safety and efficacy of long-term amiodarone therapy were examined in 12 patients who had previously developed torsade de pointes as a complication of previous antiarrhythmic therapy. The QTc intervals were determined at the time of torsade de pointes (570 +/- 40 ms), after 7 days of amiodarone loading (490 +/- 70 ms), and after 3 months of chronic(More)
A patient who presented with a new apparent seizure was found to have abnormal electrocardiographic findings, with classic features of the Brugada syndrome. He had spontaneous episodes of nonsustained ventricular tachycardia, easily inducible ventricular fibrillation at electrophysiological study in the absence of structural heart disease, and a negative(More)
A total of 40 patients with drug-refractory, life-threatening cardiac rhythm disturbances--ventricular tachycardia in 23 patients and ventricular fibrillation in 17 patients--underwent extended endocardial resection (EER) of scar tissue. Scarring was due to myocardial infarction in 38 patients, to previous congenital heart operation in 1 patient, and to(More)
