The authors described a lumbar spine fracture that is characterized on anteroposterior x-ray views by separation of the pedicular shadows. It is almost invariably associated with posterior interlaminar herniation of the cauda equina through a dorsal dural split, and anterolateral entrapment or amputation of the nerve root. The fracture is unstable and(More)
To define the long-term natural history of congenital complete heart block, we followed 27 patients prospectively by means of frequent ambulatory electrocardiographic (ECG) recordings for a mean (+/- SD) of 8 +/- 3 years. During that time, 8 of the 13 patients with a mean daytime heart rate below 50 bpm (Group A) had cardiac complications such as sudden(More)
BACKGROUND Octogenarians have been under-represented in percutaneous coronary intervention (PCI) trials, thus making difficult to choose the best type of stent in this patient population. We compared the outcomes of drug eluting (DES) and bare metal stent (BMS) at one year after implantation in this special population. METHODS A total of 320 consecutive(More)
A 32 year old patient who presented with a clinical and electrocardiographic picture consistent with an acute inferior myocardial infarction was treated with intravenous streptokinase without the aid of acute angiographic study. Subsequent evaluation revealed the initial diagnosis of acute infarction to be incorrect and the patient was found to have acute(More)
Persistent ST elevation after healing of myocardial infarction (MI) is often cited as an electrocardiographic sign of left ventricular (LV) aneurysm. This sign is rare in patients with coronary artery disease who have normal or only mildly deranged LV function and is most often associated with QRS patterns indicative of large MI, especially anterior wall(More)
To determine the utility of conventional electrocardiographic criteria for the assessment of left ventricular function, we applied pre-determined criteria to the analysis of the ECGs of 171 patients with chronic coronary disease. Eighty patients had no criteria for infarction. Seventeen had a criterion for anterior, 59 a criterion for inferior, three for(More)
