A 65-year-old woman was presented with acute abdominal pain. The initial heart rate was 170 beats/min and the ECG showed supraventricular tachycardia (Figure 1A). After intra-venous adenosine administered, it recovered to sinus rhythm and the follow-up ECG showed WPW pattern (Figure 1B). The echocardiography revealed mitral valve prolapse of mid portion of anteromedial valve leaflet (A2) with s...

The awareness of the diagnostic difficulty and the documented high mortality risk of perioperative myocardial infarction (PMI) has led to the wide use of work up to rule out PMI after major noncardiac operations. This has caused stable postoperative patients to be kept in monitored hospital beds for extended periods of time and to be subjected to additional tests. We hypothesized that the morta...

A captive, 9-yr-old castrated male tiger (Panthera tigris) from an exotic cat sanctuary and rescue facility was observed to have three collapsing episodes within a 2-wk interval prior to being examined by veterinarians. No improvement in clinical signs was noted after empiric treatment with phenobarbital. During a more complete workup for epilepsy, ventricular flutter was observed on electrocar...

Syncope is a condition often misdiagnosed as epilepsy. Syncope caused by cardiac disturbance is a life-threatening condition and accurate diagnosis is crucial for patient outcome. We present a case study of a 71-year-old woman who was referred to our epilepsy centre with a diagnosis of refractory epilepsy. We diagnosed convulsive syncope caused by malignant cardiac arrhythmia based on the prese...

OBJECTIVE To examine the traditional risk factors and biochemical profile of patients with established CAD (coronary artery disease), and compare the trends of these in specified age groups of different populations as depicted in various studies. METHODOLOGY All consecutive patients below 45 years of age, having classical history of Ischemic heart disease and also having definite ECG changes ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2014-207244 DESCRIPTION A 64-year-old man with no significant medical history was referred to the emergency department (ED) due to acute chest pain, suggestive of an acute coronary syndrome. Acetylsalicylic acid 500 mg and glyceryl trinitrate spray had been administ...

  Background: Equine chorionic gonadotropin (eCG) is commonly used in association with a progestagen treatment to synchronize estrus of goats and ewes during breeding and non-breeding seasons. Classical purification of the eCG from serum includes pH fractionation with metaphosphoric acid two ethanol precipitation steps as...
