An atypical arrhythmia

An atypical arrhythmia

There is a narrow complex tachycardia with a rate of approximately 160 beats/min. The electrical axis is intermediate (almost vertical). In every supraventricular tachycardia the position of the P wave is critical for the diagnosis. Here the P wave seems to be present 120 ms before the QRS complex (i.e. long RP, short PR interval). The P-wave configuration is negative in leads II and III and po...

Apical hypertrophic cardiomyopathy with hemodynamically unstable ventricular arrhythmia - Atypical presentation.

We present a patient with asymptomatic apical hypertrophic cardiomyopathy (AHCM) who recently developed cardiac arrhythmias, and shortly discuss the diagnostic modalities, differential diagnosis, and treatment strategy for this condition. AHCM is a rare form of hypertrophic cardiomyopathy, which usually involves the apex of the left ventricle. AHCM can occur with varied presentations such as ch...

Odontogenic Fibroma of the Maxilla - An Atypical Presentation

Odontogenic fibroma (OF) is considered an unusual, benign mesenchymal neoplasm and one of the most little-understood lesions amongst all odontogenic neoplasms. The incidence rate of the tumor is from 0% to 5.5%. WHO classified them into intraosseous or central and extraosseous or peripheral variants. It chiefly consists of fibroblastic tissue with an inconsistent amount of inactive appearing od...

An atypical cause of atypical chest pain

The present report describes a case involving a 57-year-old HIV-positive man who presented with acute retrosternal chest pain accompanied by 24 h of fever. Septic arthritis of the manubriosternal joint was diagnosed based on magnetic resonance imaging findings in addition to Staphylococcus aureus bacteremia. To the authors' knowledge, the present case is only the 12th reported case of manubrios...
